Greenrock SCP™ is a construction material designed to solve many of the problems associated with Portland cement. It has an extremely high compressive strength, a relatively fast cure time and provides electrical isolation and chemical resistance. It has no shrinkage, contains no VOCs, can be precast or poured in place and does not require any reinforcing materials. Greenrock SC P has been successfully used in manhole risers, wet wells and lift stations, sanitary sewer pipe, chemical containment sumps, electrolytic cells and equipment bases. Most recently it is being used to replace deteriorated wood ties in the subway rail track.
