Crystalline waterproofing systems

Adi-Con CW Plus is a crystalline admixture whose proprietary reactive chemicals integrally waterproof concrete and mortar. Along with products of cement hydration, the chemicals spur formation of a nonsoluble gel throughout the matrix pores and capillary tracts. The admixture reduces concrete permeability; protects surfaces from chloride exposure and carbonation; and, reduces deterioration attributable to chemical attack and reinforcing steel corrosion.
