Techniques to Enhance Home Value

Posted on October 15th, by Miles Chaffee in Milestone Blog. No Comments

Permeable concrete pavers Boston

As any home buyer knows, the value of your investment depends on what you do with it. Whether you are making your property better for a sale or simply for your own enjoyment, there are a number of strategies one can employ. Keeping a home tidy and well-manicured is a good start, but what if you did more? Lush landscaping can really improve the curb appeal of a home, and at times bring an entirely different aesthetic appeal. Another option is the installation of a patio, deck, or outdoor fireplace to host guests. One option you may have not considered before is that of a porphyry driveway.

Porphyry Stone

The inclusion of porphyry stone is an update to your property that also serves as a throwback to another era. The European touch of the cobblestone-like driveway can complement … Read More »


Porphyry Stone Among Incredible Art

Posted on September 22nd, by Roger Murphy in Milestone Blog. No Comments

Porphyry in this installation is paired with other beautiful stones and mosaics for an amazing experience.  When I have visited other Porphyry installations, the Porphyry is the prominent feature.  At this beautiful church, the Porphyry shares the spotlight with stone carvings, stone and glass mosaics, frescoes and a one of a kind pipe organ. 

The church overlooks Rock Harbor near Orleans, Massachusetts on Cape Cod. The main building material cladding is Kasota limestone or simply, ‘Kasota stone’.  It is a dolomitic limestone found in southern Minnesota This sedimentary rock is part of the Oneota Dolostone Formation of southern Minnesota and is approximately 450 million years old. This particular limestone is rich in dolomite and magnesium  making it resistant to weathering, and

it is thus widely used as a building material. Its name is taken from Kasota  township where the stone has been quarried. This is the same stone that … Read More »


Porphyry Paving – The Financial Value

Posted on September 11th, by Roger Murphy in Milestone Blog. No Comments

The tradition of stone paving with stones like Porphyry is centuries old.  Most of our stone knowledge comes from the European quarries and stonemasons.  This blog presents research involving the paving and hardscape designs with natural stone. So much of this research emanates from Europe and the United Kingdom.  Part of this is because of the preservation activities and the rest is due to new installations of the age-old material.

The publication, Paved with gold – The Real Value of Good Street Design, produced by the Commission for Architecture and the Built Environment (CABE) demonstrates how street quality relates to higher real estate prices and higher retail rental rates.

 

Paved with gold shows how we can calculate the extra financial value that good street design contributes, over average or poor design. It shows how clear financial benefits can be calculated from investing … Read More »


Porphyry Paving – Overlapping Arcs

Posted on September 7th, by Roger Murphy in Milestone Blog. No Comments

Porphyry paving cubes for use in an overlapping arc pattern is one of the oldest designs for stone pavement.  It has continued in use for centuries due to its stability, beauty and pleasing intricacy. 

In Europe, one of the more popular layouts is the bogen also known as an overlapping arc, which is often mistaken for a fan but is actually a series of stacked arcs.  The bogen layout is complex and requires the skills of an experienced artisan as the setts at the ends of the arcs, where one arc meets its neighbor, need to be somewhat smaller than those in the center of each arc.

Traditionally, bogens are incredibly strong layouts as the arcs work to dissipate forces over a much larger area. Their development and use reached a peak when horse-drawn traffic dominated the streets, but since the advent of modern … Read More »

Porphyry Paving with Smolleri

Posted on August 25th, by Roger Murphy in Milestone Blog. No Comments

Porphyry paving with  Smolleri or “Slabs on Edge” is traditionally used  for paving surfaces on steep slopes as they present the maximum roughness and the natural split surface is used as a decking for grip.  Smolleri are ideal for the paving of roundabouts and other high stress traffic situations. 

Smolleri can add textural variation to  contemporary paving schemes and can also be used for vertical cladding of walls (both inside and outside).  The sides have a natural surface variation in widths (in plan) of between 60mm to 130mm.  Depths range from 30-70mm. Lengths can be random or cut to size.

 

From The Porphyry Manual:

“In the 20’s and 30’s coarse tiles or “smolleri” began to be used to pave sloping surfaces in many mountain villages in Trentino, Italy.and also in Lombardy and in Veneto. They are little slabs of porphyry, in the past they were very thin, now of variable thickness … Read More »


GftK Pavement Jointing Mortar Best Choice

Posted on August 18th, by Roger Murphy in Milestone Blog. No Comments

GftK’s vdw 850 jointing mortar was selected for a sensitive project in Hitchin, Hertfordshire.  The old Market square project presented various challenges to dealing with the 750 sq. meter area of time worn granite and basalt setts.  Weather and disruption of business were among the many. Re-jointing was specified over re-laying and Vdw 850 was selected over several possible materials.  Gftk’s vdw 850, is the product for light traffic and sidewalks.  This has a medium permeability rate of 2 quarts / min/ 10 sf at 20% joints. Its compressive strength is 3,625 psi at 20% joints. (High performance for medium traffic)

Porphyry’s role in Living Streets

Posted on June 23rd, by Roger Murphy in Milestone Blog. No Comments

Porphyry and other natural stone products are seen throughout this report, used as specialized paving elements.  Most of the concepts here revolve around traffic calming and storm water management embracing the multiple users of our streets, not just motorized vehicles.

“Living streets have no separate sidewalks or curbs and gutters, but rather provide a shared space that is safe and accessible for pedestrians, wheelchairs, cyclists and low-speed vehicles. They also allow for integrated percolation and drainage through cen­terline drainage, landscaping and the use of porous paving materials.” According to the report

To keep traffic speeds low enough to make it safe for pedestrians and children, traffic calming mea­sures are designed to cover the entire street cross-section. These measures include the use of special paving materials, tree plantings, the arrangement of vehicle parking, vertical shifts such as raised intersections, road narrowings at entrance … Read More »

Porphyry Cubes used in Modern Roman Paving

Posted on June 3rd, by Roger Murphy in Milestone Blog. No Comments

Porphyry cubes were used in a large urban project in Rome.  The Piazza dei Navigatori is a Roman square located along Via Cristoforo Colombo, one of the main roads in the city of Rome because of its size, its role as a link between the city center and the sea and its importance to the city. The objective pursued during the work was to redefine all the gardens, the pedestrian area and a whole series of other operations. Reworking this area to prepare for development involved new circulation of existing roadways in order to accommodate vehicular traffic and pedestrians and reimagine the landscape. The commercial/hotel project shown here was part of the overall development.

Porphyry cubes are cube-like shaped paving elements obtained by means of mechanical splitting, with natural surface.  Cubes are made in different sizes on the basis of the … Read More »


GftK Paving Mortars Save Time and Money

Posted on May 27th, by Roger Murphy in Milestone Blog. No Comments

The scheduled opening in March 2009 was fast approaching, and the February weather was cold and wet – totally unsuitable for pointing with cement based materials. However the contractor solved the problem by using GftK Epoxy Resin Pavement Jointing Mortars that enabled the work to continue whatever the weather, plus the majority of the joints were actually pointed by a team of only three men in a SINGLE DAY. While the cost of the GftK Jointing Mortar was substantially higher than sand and cement, the labor savings alone meant that the jointing costs were almost equivalent; with the incredibly fast application speed of GftK materials also allowing completion on time for the opening, saving precious schedules and financial commitments.

Porphyry Paving and Toronto Woonerf Design Innovations

Posted on May 12th, by Roger Murphy in Milestone Blog. No Comments

Stone paving like Porphyry is an element of hardscape used in a woonerf. The first of many opportunities to use the concept of a woonerf is happening in one of the multi faceted areas under the influence of Waterfront Toronto. This area is called the West Dons Land, one of the six main areas of development. The use of stone paving is prevalent in current designs throughout all the areas.

Woonerfs – an innovative street design – will be used for some of the area’s local interior streets. Woonerfs, or living streets, are pedestrian-oriented roads that blur the boundary between sidewalk and street and provide a common public space shared by pedestrians, cyclists and low-speed motor vehicles. Commonly found in Europe and elsewhere, the West Don Lands is the first place they will be used in Toronto.

If all goes well, woonerfs … Read More »


Porphyry and Widemarsh Street

Porphyry and the value of distinctive paving materials

Posted on April 14th, by Roger Murphy in Milestone Blog. No Comments

Stone pavers like porphyry and its more expensive granite cousin are being designed into numerous places in Toronto.  This blog has previously highlighted the wonderful designs and work by WaterFront Toronto, now the nearby entertainment district is re-imagining one of their main streets. Distinctive paving materials and patterns are a necessary part of the project recommendations as well as a continuous “mountable” curb. The curb, on both sides of the street will enable a seamless transition into a pedestrian-only space for events.

Excerpts from the EA Study – John Street Corridor Improvement

In recent years, there has been growing recognition of John Street’s potential for Toronto including its designation as one of four streets that are ‘Cultural Corridors’ (City of Toronto, ‘Canada’s Urban Waterfront: Waterfront Culture and Heritage Infrastructure Plan’, 2001) and within an area identified as the ‘Avenue of the Arts’ … Read More »


Porphyry and Living Streets

Posted on April 8th, by Roger Murphy in Milestone Blog. No Comments

Porphyry stone surfaces on sidewalks, streets and plazas create memorable and enchanting environments. Stone is prominent in our most cherished streets worldwide. They were developed before the age of the automobile.  These historic and human scaled streets invite people to spend time there. Today, society is moving toward a more sustainable way of life, with cities everywhere aspiring to become high-quality places to live, work, and play. Streets are fundamental to this shift. They define our system of movement; create connections between places, and offer opportunities to reconnect to natural systems. There is an increasing realization that the right-of-way is a critical and under-recognized resource for transformation, with new models being tested to create a better public realm, support balanced transportation options, and provide sustainable solutions for stormwater and landscaping.

Porphyry and Curbless Streets – Part 3

Posted on March 31st, by Roger Murphy in Milestone Blog. No Comments

Porphyry paving can be a functional stormwater amenity as well as an aesthetic enhancement, when designed as permeable porphyry paving. This is accomplished with a high performance jointing mortar that is also permeable, vdw 800 by GftK.  In the examples of curbless streets in recent blogs, the main stormwater design depends on sheet flow to move water to a landscape feature or a berm where infiltration takes place.  By using a new high performance grout with the pavers, the entire installation can be permeable.

 

First and foremost, permeable paving goes against everything we’ve ever learned about modular paving. In the past, paving was done in such a way that water runs right off it. However, with permeable paving we want the water to go through it. Another thing about permeable paving is that the materials used for all key elements of … Read More »


Porphyry and Curbless Streets – Part 2

Posted on March 24th, by Roger Murphy in Milestone Blog. No Comments

Porphyry stone pavers can be used on pedestrian surfaces, vehicle surfaces, as well as transition areas. This beautiful and sturdy stone will make any of these memorable. Special paving treatments can enhance the aesthetics of public spaces in a city, give circulation areas a stronger sense of place, and enhance the hierarchy of public spaces. 

In new street design, typically the decision to have curbed or uncurbed streets depends on the street’s desired traffic capacity and speed. In general, the higher the traffic speed and the less pedestrian-oriented the street is, the more likely that it will require a raised curbed street edge. Conversely, streets that have slower traffic and are more pedestrian friendly are good candidates for a curbless condition. Even commercial streets with on-street parking can be designed as curbless streets if there is enough right-of-way space and traffic … Read More »


Porphyry and Curbless Streets – Part 1

Posted on March 19th, by Roger Murphy in Milestone Blog. No Comments

This first in a series of three blogs about paved streets, public spaces and sidewalks where the street design incorporates curbless streets.  This discussion explores the concept first created in the Netherlands, a woonerf.  Porphyry and other stone pavers figure prominently in these designs.

So what is a woonerf exactly? Picture a regular street, but narrow, minus a curb, finished with pavers instead of asphalt. Developed by Dutch traffic engineer Hans Monderman, a woonerf is a street where pedestrians and cyclists have legal priority over motorists as implemented in the Netherlands and in Flanders. Techniques include shared space, traffic calming and low speeds. This concept goes by a number of other names, such as Living Streets and Complete Streets in the USA, and Home Zones in the UK.

Porphyry in the Vatican

Posted on March 11th, by Roger Murphy in Milestone Blog. No Comments

Porphyry pavers in various sizes are used now to improve the surfaces of all hardscape projects. Once, there was a more decorative use for porphyry in the interior. Rome and especially the Vatican are filled with imperial porphyry. The museums, churches and chapels of Vatican City have more imperial porphyry as sculpture and decoration than anywhere else. The Imperial Porphyry found here came from a single mine in Egypt, the Mons Porphyrites.  It was imported by the Romans as a decorative accent stone, for use in tiled floors, as colored columns, or occasionally carved into a vase or sculpture.  Its color invokes Royal Purple.

Porphyry is extremely hard, also dense and heavy.  Even lifting a substantial hunk of porphyry is a great feat, let alone transporting it by ship from Egypt.  It is also so hard that it takes very strong, … Read More »


Porphyry Pavers and GftK High Performance Jointing Mortars

Posted on March 4th, by Roger Murphy in Milestone Blog. No Comments

Breakthrough high performance jointing mortars coupled with Porphyry stone paving products provides the strength, beauty and durability needed for commercial applications. The following project shows how these were used together in the Newark Market  Square in Newark, Nottinghamshire.

Since 1999, Newark District Council has been undertaking an improvement program to the medieval market square using 100mm Porphyry stone setts laid in a traditional bogen (overlapping arcs) pattern. The square still stages open air markets and other activities on at least 6 days a week, and the area is used by delivery vehicles, as well as normal traffic, all of which can leave a bit of a mess. Consequently, regular machine cleaning has to be undertaken, which imposes yet another stress to the pavement.

Some months ago, the Council identified GftK mortars from NCC Streetscape as a possible solution to all of these problems … Read More »


Resurgence in the use of paving stones

Posted on February 28th, by Miles Chaffee in Milestone Blog. No Comments

Porphyry paving stones and cobblestones have been used globally for millennia in streets and roadways because of their durable nature. In theUnited States stone paving represented growth and stability as great cities developed at ocean and river ports through out the country and were used as a stable foundation for commerce. Cobblestone streets, used for centuries in our oldest cities, have with the advent of the automobile been covered over with asphalt or dug up and sold a scrap.

Today you can see resurgence in the use of paving stones through out the country. Urban centers are incorporating stone paving into street designs, parks and commercial centers. Washington Park in Cincinnati,Ohio and the Boiler Maker Shops in Washington,DC are great examples of this.

Porphyry paving and the Glasgow Financial District

Posted on January 28th, by Roger Murphy in Milestone Blog. No Comments

Porphyry paving was incorporated into this project to give it special status. This project comprehensively refurbished the public realm of six streets and formed an essential part of the Broomielaw area’s renaissance as part of the Glasgow International Financial Services District. Since completion, investment in the area has accelerated and new developments are rapidly coming on-stream.

The design delivered new footways paved with natural stone surfacing in porphyry and granite with Scottish whinstone kerbs. Stainless steel furniture, signage and street lighting complemented the pavements and the surrounding buildings.

Porphyry like natural stone cobbles and setts are front and center in several of Waterfront Toronto’s projects, adding permanence, beauty and creating a fundamental sense of place. The role of natural stone is evident throughout many of the projects. Granite is used in these, but porphyry could be substituted for the same durable and attractive purpose.

Waterfront Toronto has undertaken a multi-year,  multi-location set of projects to reclaim and enliven the waterfront. Among them is the transformation of Queens Quay. What’s now a messy and dysfunctional downtown thoroughfare will become an elegant street shared equally by cars, public transit, pedestrians, cyclists — and trees. The remake of Queens Quay has been in the works for years, but, says Dutch landscape architect Adriaan Geuze, that’s to be expected. In 2006, Geuze’s firm, West 8, won an international competition to redesign the Central … Read More »


Porphyry Featured in new Diesel Headquarters

Posted on January 7th, by admin in Milestone Blog. No Comments

Porphyry stone pavers were chosen for the pedestrian walkways and gardens of the new Diesel Headquarters.  It is located in Breganze, a town in the northern Italian province of Vicenza.  Diesel S.p.A. is an Italian design company. It is best known for luxury, ready to wear, clothing aimed at the young adult market. The architect for the project was Studio Ricatti.

The Porphyry paving, in fact, embellishes a traditional environment and also combines in a pleasant manner with the new buildings. Porphyry has been processed and laid with an interpretation of the stone in a modern and highly-advanced context. This project made use of grey color cubes of about 25,000 square feet, laid in straight lines, and cut slabs, also grey, of about 7,000 linear feet.  A play of combinations of material and color which makes it possible to create new effects which … Read More »


Porphyry and New City Spaces

Posted on December 24th, by Roger Murphy in Milestone Blog. No Comments

Porphyry and other stone pavers are throughout this book about important examples of urban public spaces worldwide. The upsurge in interest in public spaces and public life over the past twenty five years has generated an impressive array of city plans, public space strategies, and designs. This book presents an overview of this development and provides a detailed description of architecturally interesting and inspiring public space strategies and projects from all over the world. Nine cities with notable public space strategies were selected for special review: Barcelona,  Lyon, Strasbourg,  Freiburg,  and Copenhagen in Europe, Portland in North America, Curitiba and Cordoba in South America, and Melbourne in Australia. In addition, thirty nine international public space projects are presented and discussed. Drawings, plans and photographs illustrate city strategies and public space projects in detail.

Porphyry and Urban Streets

Posted on December 18th, by Roger Murphy in Milestone Blog. No Comments

“We go back to some streets more often than to others…maybe a street unlocks memories or offers expectation of something pleasant to be seen…streets are places of social and commercial encounter and exchange…a place to be comforted by the presence of others.”  - From Great Streets by Allan B Jacobs

Porphyry pavers have been used in the making of memorable streets and places from ancient times to modern day.  A new guide to urban street design is available for local governments to peruse.  It was created by the very transportation officials that are implementing policy.

The National Organization of City Transportation Officials (NATCO), a network of big-city transportation departments, recently released the Urban Street Design Guidebook.  It is available for download here. Please see the full blog post to download this guide.  It has been created in an effort to outline the “21st-century … Read More »


Porphyry and the Color of the Year 2013

Posted on December 10th, by Roger Murphy in Milestone Blog. No Comments

Porphyry paving and the green lushness of the landscape go hand in hand. “Green is the most abundant hue in nature – the human eye sees more green than any other color in the spectrum, as it has throughout history, multifaceted Emerald continues to sparkle and fascinate. Symbolically, Emerald brings a sense of clarity, renewal and rejuvenation, which is so important in today’s complex world.”

Get ready for a verdant 2013. Pantone has just declared Emerald (17-5641 on your fandeck) the “lively, radiant” Color of the Year. It’s a jewel-toned follow-up to the tropical shades favored by the color authority in recent years, such as last year’s Tangerine Tango, which was preceded by Honeysuckle, Turquoise, and Mimosa.

“As it has throughout history, multifaceted Emerald continues to sparkle and fascinate,” said Pantone Color Institute executive director Leatrice Eiseman in a statement announcing the pick. “Symbolically, Emerald … Read More »


Porphyry and the Quality of Place

Posted on December 4th, by Roger Murphy in Milestone Blog. No Comments

Can beautiful Porphyry pavers make you smarter, more creative and like your community more?  From three diverse expert sources comes information about how the built environment affects people and why it matters.

Academy for Neuroscience for Architecture

This is admittedly an abstract concept, to help explain, architects often tell this story: Early in his career, when he was still struggling to find a cure for polio, Jonas Salk retreated to Umbria, Italy, to the monastery at the Basilica of Assisi. The 13th-century Franciscan monastery rises out of the hillside in geometric white stone, with Romanesque arches framing its quiet courtyards. Salk would insist, for the rest of his life, that something about this place—the design and the environment in which he found himself—helped to clear his obstructed mind, inspiring the solution that led to his famous polio vaccine.

He really thought there was something … Read More »


Porphyry, Walt Disney and the Architecture of Reassurance

Posted on November 26th, by admin in Milestone Blog. No Comments

Porphyry and What Walt Disney knew about cities.

Walt Disney knew the impact on the senses of cobblestoned streets and plazas. In recent years Disney-urbanism has colonized authentic cities. Urban entertainment districts such as South Street Seaport in New York, Quincy Market in Boston, and Harbor Place in Baltimore are good examples. South Street Seaport conveys the impression of a once-active seafaring culture, but without the messiness of a functioning seaport – the smell of fish, working-class dockhands, clamoring fish mongers. Instead we find national retail and restaurant chains like The Gap and McDonald’s.

It is the seemingly urban and authentic character of these districts (real cobblestones, 100-year old brick facades, and a carefully displayed historic ship) that make the usual retailers feel new. Visitors are usually tourists – everyday people living inNew York, for example, recognize that something about South Street … Read More »


Porphyry, Placemaking and Public Space

Posted on November 20th, by admin in Milestone Blog. No Comments

Porphyry stone paving can be an essential ingredient, one of many, that contributes the element of permanence, beauty and sustainability to a place. It is a material that defines a space as comfortable, memorable, elegant and special.  It helps people want to go there.

Public spaces are increasingly being recognized as a crucial ingredient for successful cities and for their ability to revitalize and create economic and social development opportunities. But actually finding ways to build and maintain healthy public space remains elusive to many municipal governments, especially in the developing world. The vast web of streets, parks, plazas, and courtyards that define the public realm is often lacking, too poorly planned, or without adequate citizen participation in the design process.

Recognizing these challenges, the Project for Public Spaces (PPS) released earlier this month a draft of their handbook Placemaking and … Read More »


Porphyry salutes award winning Sugar Beach

Posted on November 12th, by admin in Milestone Blog. No Comments

The use of traditional stone similar to Porphyry pavers are part of the award winning design of this urban park. Canada’s Sugar Beach is a whimsical new park that transformed a surface parking lot in a former industrial area into Toronto’s second urban beach at the water’s edge. 

Part of the multi-faceted Waterfront Toronto project previously highlighted in this blog, this park is in the East Bayfront section. Located at the foot of Lower Jarvis Street adjacent to the Redpath Sugar Factory, the 8500 square meter (2 acre) park is the first public space visitors see as they travel along Queens Quay from the central waterfront. The park’s brightly colored pink beach umbrellas and iconic candy-striped rock outcroppings welcome visitors to the new waterfront neighborhood of East Bayfront.

The Porphyry setts, used on Via Manin are unique in terms of physical, chemical, geological and mineralogical properties with features that distinguish it from all other stones. Via Manin is located in the heart of Mestre.  It is an important road that ends up in Piazza Ferretto, the elegant center of this Veneto city.  Via Manin, one of the main roads in Mestre, had been neglected for years.  Now it has been given new life and splendor thanks to renovation.

Every square and every road in any city is always much more than just paving.  They consist of people, citizens who stroll along them, shops that work and residents.  These are the people who were to be given back this historic road.

Porphyry – Stone Surfaces 2

Posted on October 16th, by admin in Milestone Blog. No Comments

Porphyry stone pavers can have a unique place in the design of any outdoor area. Stone is undoubtedly the first natural material which was used to create stable surfaces which could withstand heavy loads, making it possible for people to walk around easily, even when it was raining – safe and comfortable at the same time, very flat, and practical.  From this beginning, the desire to create beautiful designs out of this practical material has been the work of architects, landscape architects, landscape designers and professional installers.

“If we add the creativity of landscape designers and the know-how of stone craftsmen, the outcome is necessarily unique and enriches the colorful palette of garden art as time goes by. Stone mixes with stone to enhance harmonious contrasts and reveal the diversity of our subsoil. It harmonizes with wood, concrete, brick or steel, … Read More »

Porphyry and the Terminated Vista

Posted on October 2nd, by admin in Milestone Blog. No Comments

Porphyry pavers are used to enhance the experience in many examples of places with a terminated vista. While there are many other elements present, which lead to the special experience of these views, the stone paving lends permanence and visual memory to these elements.  An alley in Portland, Maine; a street in Paris; or a plaza in Mexico; there is something special added to the scene with stone pavers.

One principle of great design is the “terminated vista,” a landscape or building at the end of your line of sight that sort of takes your breath away.  If you keep your eyes open the world is full of small, pleasant, and surprising sights.

 

A Terminated Vista is not your loss of view out the window or out to sea or whatever, at least not as a planning term; but it is about something … Read More »


Porphyry and the Opus Incertum

Posted on September 24th, by admin in Milestone Blog. No Comments

Porphyry – Opus Incertum or Porphyry crazy paving is most suitable for surfacing external areas like patios, drives, pavements or external and internal wainscoting. It complements designs with water and vegetation, assuring warmth and color in the environment.

Opus incertum (L, = irregular order pattern) Ancient roman technique in which the stones are arranged casually. Used for wide pavings or as a background to the setting of other figures in opus musivum    

 

QUARRYING AND SORTING

From the open quarry face, small amounts of explosives are used to bring down the stratified material. The porphyry thus quarried is first separated with mechanical shovels and the waste material, in this phase composed of “cappellaccio” (the top weathered part), earth and fault intrusions, is loaded on to lorries and sent off to various destinations (land fill, reclaimed land, crushers, banks of rivers, rubbish tips.

Much has been written recently about the concept of complete streets.  A complete street recognizes that the purpose is not to help an automobile to get from point A to point B, but to provide for pedestrians, cyclists, rapid transit, automobiles and to do so safely and with appeal.  These multipurpose streets are supposed to enhance everything from walkability to the economy.  Much of the writings take the form of manuals and guides about what to review, what to consider and how to make room for all the elements required.  There are design typologies for a wide variety of street types.  … Read More »


Porphyry and Historic Renovation

Posted on September 13th, by admin in Milestone Blog. No Comments

Copper Mountain Porphyry pavers and cubes were chosen for the sidewalks, plaza and courtyard of the Dona Ana Village restoration.  It is interesting that porphyry was not part of the original paving material at the site, but the beauty and physical characteristics became an easy choice. It blends perfectly in this historic context and will outlast any other material.  Dona Ana was settled around 1650, by Spanish land grant settlers. It is on the famous Camino Real, The Royal Road.  In 1854 Mexico sold this territory to the U.S. as part of the Gadsden Purchase.

Doña Ana County hired Conron & Woods to document and develop preservation plans for a compound of three 1840′s adobes in the historic Doña Ana Village just north of Las Cruces, New Mexico.

Porphyry – Natural Stone Surfacing of Streets

Posted on November 14th, by admin in Milestone Blog. No Comments

Stone Streets

 First published in 2000, by the Society of Chief Officers of Transportation in Scotland (SCOTS), Natural Stone Surfacing – Good Practice Guide, was responding to the following regarding their city center streets.

“The techniques used in installing stone surfaces which perform well, vary throughout Europe.  They are based on semi empirical, traditional, guidance borne of experience rather than engineering knowledge.  No unified guidance exists.

 This guide has been developed to address this lack of engineering understanding and is based on a programme of research, tests and trials from which practical guidance based on engineering principles has been developed.”

  Lost Knowledge

In the 1950’s as many as 30% of Scottish city streets were paved with stone.  Beauty, long life and repairability headed the list of reasons.   60 years later, it was found that the traditional skills and knowledge associated with stone laying had been lost.  These … Read More »

Laying Specification – “Porphyry Pavers for Vehicular Traffic”

Posted on September 28th, by admin in Milestone Blog. No Comments

Porphyry Driveways, Porphyry Streets, Porphyry Plazas all can benefit from this installation specification.  The Sustainability, Beauty, and Life Cycle Cost of natural stone pavers is an ever increasing choice for hardscape designers.  The techniques and skills for laying these stones has more roots in Europe than in North America and even there, the word of mouth, father to son training has required formalizing the methodology as each generation loses some of the knowledge.

Unbound refers to flexible paving vs. rigid paving.  There is no cement used in the sub base, base, or jointing materials.  The interlock achieved by proper installation, compacting and edge restraints creates a resilient, load bearing, lifetime surface.  This method is very easily repaired if digging up utilities at a later date is necessary.

 Setts often are incorrectly called cobblestone and in the literature are interchangeable. Technically the sett is a … Read More »

Porphyry Pavers: Aspect Ratio, Plan Ratio, Plan Area, Modular Ratio

Posted on May 22nd, by admin in Milestone Blog. No Comments

The shape of the stone unit determines how the stone surface responds under load and the way in which the load will be resisted.  Certain shapes of units are better suited to particular forms of construction.  While they all can be appropriate for pedestrian use, driveway and city streets have tighter parameters to pay attention to.

These terms are used throughout the paver industry:

Aspect Ratio – The overall length of a paver divided by its thickness of the paver unit.

Plan Ratio – The overall Length of a paver divided by its width.

Plan Area – The Length times the Width of the paver.

New  – Modular Ratio – The relationship between the depth of a unit and its plan area.

Laying Porphyry Paving “Pose de Paves”

Posted on May 21st, by admin in Milestone Blog. No Comments

A Porphyry installation video of a beautiful cobblestone pathway is educational. This short (2:21) segment showing two posers (layers) and a helper laying overlapping arcs with 4” (8-10cm) porphyry cubes, demonstrates an effortless seeming process of a traditional setting method that dates back centuries.  The stone setting skill of these two is highly refined and belies the years of training and experience they demonstrate.

  

Porphyry paving is an old world material, a type of volcanic igneous rock. This material used with installation professionals can achieve stunning areas that will heighten the aesthetic value of the surroundings.  Cubes lend themselves to many different patterns. It is exciting to watch this installation performance.

The overlapping arc pattern is the most wide spread pattern that easily suits every kind of area.  This is the reason it is also called “normal” lying.  This and other patterns … Read More »


What is Porphyry?

Posted on April 29th, by admin in Milestone Blog. No Comments

Porphyry has been used as a paving surface as far back as the Roman era.  The Romans used it because it had a naturally flat, durable surface and the stone was easy to quarry.

 Traditional porphyry is a variable thickness stone.  It’s a type of granite that has naturally extruded through the earth’s crust.  Unlike most granites, it fissured in layers due to seismic activity.  These fissures caused cooling in the formation, further causing larger crystals to form around smaller crystals, giving the stone its unique appearance and texture.

 

 Because the formation has vertical layers, extracting the stone requires very little energy – far less than sawing granite out of monolithic, block formations, and far less pollution than the heat and carbon dioxide expelled during the process of making concrete pavers.  When porphyry is blasted out of its formation, it comes out … Read More »
