Improving Products Through Advanced Material Science

The Technology
The Material Science

The company’s Intellectual Property is based upon a continuum of formulary that range from:  a lightweight cementitious (cement-based) formula with weights as light as wood while still achieving compressive strengths comparable to concrete, to stronger, denser and heavier composites with strengths of two, three, and four times those of concrete while able to be cast and poured as thin as 1/4-1/2".  Each of these is based upon the fundamental building blocks of concrete.  CarpenterStone has developed a combination of chemicals and processes that allow us to produce composite materials that are stronger and lighter than previously possible.

We separate our general technology into two categories dependent upon their integral qualities.  The technology that provides materials so light and strong that they can be tooled and installed by a CARPENTER...is CarpenterStone lightweight. 

The technology that produces our various mixtures that are as strong and dense as STONE...we refer to as the Doverra series.
