Cast-to-Order Solid-Surfacing Material A cement-based composite of natural minerals and recycled materials, Syndecrete has twice the compressive strength of ordinary concrete at less than half its weight. Solid slabs for tubs, counter or vanity tops, basins, backsplashes, and flooring are precast to your specifications to be finished and fitted on site. Available in densities ranging from 35 to 100 lb/cf, this material has the workability of wood — surfaces can be ground, polished, or textured like Italian terrazzo. Syndecrete is resistant to staining, corrosion, and impact damage.
