Xypex Concentrate DS-1

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

Xypex DS-1 is a special dry shake formulation of Xypex Concentrate and is designed specifically for horizontal concrete surfaces such as parking decks and floor slabs. DS-1 is trowelled into fresh concrete prior to finishing.

Xypex Dryshake products, for horizontal surfaces, are part of the Xypex concrete waterproofing and protection system and represent one of three different ways to install Xypex Crystalline Technology into 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.

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

Concentrate DS-2 provides these same properties but additionally enhances the abrasion resistance by incorporating a hardener.
