Concentrate DS-1 is formulated specifically for waterproofing and to provide protection from aggressive chemicals.

Xypex Concentrate DS-1 and DS-2 are Xypex "dryshake" products installed into the horizontal surface of freshly laid concrete.

Concentrate DS becomes an integral part of the concrete surface thereby eliminating problems normally associated with coatings (e.g. scaling, dusting, flaking and delamination). The active chemicals react with the moisture of the fresh concrete causing a catalytic reaction which generates a non-soluble crystalline formation within the pores and capillary tracts of the concrete.
