Xypex Concentrate 50 Lb Bag Gray Crystalline Wtrprf

50 Lb Bag, 10 Min Touch Dry Time, Particulate Powder, Cementitious Crystalline, Concentrate, Gray Crystallization™ Concrete Waterproofing

Xypex is a unique chemical treatment for the waterproofing, protection and repair of concrete. XYPEX CONCENTRATE consists of Portland cement, finely graded sand and active proprietary chemicals; It is applied as a cementitious slurry to the pre-saturated surface of existing above and below grade structures. The active chemicals diffuse into the substrate and react with moisture and the constituents of hardened concrete to cause a catalytic reaction. This reaction generates a non-soluble crystalline formation throughout the pores and capillary tracts of the concrete, as well as cracks, permanently sealing the concrete and preventing the penetration of water and other liquids from any direction even under high hydrostatic pressure. Xypex Concentrate is also mixed in a Dry-Pac form for sealing strips at construction joints or for the repairing of leaking cracks, faulty construction joints and other defects. Hardens and toughens cement mortar for improved durability; Enhances adhesion capabilities to a wide variety of surface; Increases resistance to many industrial chemical; Eliminates water curing; NSF 61 certified when used with Megamix I.
