PAVERS
Clay pavers are a strong contributor to green-building design and sustainability and are made from clay and shale two of the most abundant natural materials on earth.
At how often the suggestion of a paving material that will harmonize the landscape into that vision will lead to additional work for you.
Durability and permanent color retention
The unsurpassed durability and rich, intense color of a clay paver is one of its most desirable and enviable attributes. Amazingly, many of the brilliant, red pavers that people stroll on when walking through Boston's Beacon Hill have been in service for more than 200 years. While lower, initial-cost options are available, this longtime track record speaks volumes about how long the product will last and the quality that your customers get for their money.
The reason for the superior color retention of clay pavers is that the color is from natural impurities within the clay, which means that color is consistent throughout the body of the unit and will not fade due to weathering. Other segmental paving products, like those made from concrete, have to get their color artificially from pigments or dyes and may require application of sealants to maintain their color after installation.

Clay pavers are stronger then people may think. Shown are Whitacre-Greer pavers used vehicular application on Marion Street in Oak Park, III.
Compressive strength
Many contractors and designers do not realize just how strong clay pavers are. In fact, clay pavers have an average compressive strength of 14,000 psi stronger than the standard for both concrete pavers and poured concrete. Some clay pavers have a compressive strength of more than 36,000 psi. So, they are resistant to abrasions, stains, deicing salts, and other elements.
Compatibility with accessibility requirements
Research from the University of Pittsburgh proves that properly installed clay pavers can meet or exceed the American with Disabilities Act requirements and Public Right-of-Way Accessibility Guidelines by not increasing the amount of work required for mobility and offering less vibration than many poured concrete sidewalks. Ensuring that joints between pavers aren't too wide and that differences in height between adjacent pavers are kept to a minimum reduces work and potential trip hazards. It also assures an ability to compete with other pavement options as an accessible surface.
Sustainability
Clay pavers are a strong contributor to green-building design and sustainability and are made from clay and shale - two of the most abundant natural materials on earth. The small size, modular nature and minimal packaging of brick
