Xypex® Waterproofing

As a preferred certified applicator we have completed millions of square feet of Xypex Coatings. Because of our experience we can provide a Ten Year Watertight Warranty with our installs on new and existing structures.

We specialize in water/waste water treatment structures, parking structure and below-grade foundation waterproofing. We use Xypex to repair leaking cracks and construction joints.

  • Holding basins
  • Elevator pits
  • Culverts
  • Basements
  • Parking structures

How Xypex Works

Xypex Crystalline Technology waterproofs and enhances the chemical protection of concrete though its unique reactive process.

The active chemical components in Xypex react with the by-products of cement hydration, resulting in a non-soluble crystalline structure that fills and plugs the pores and capillary tracts of the structure. In this way, the concrete becomes impermeable to water and other liquids and is protected against chemical attack.

To create its crystalline waterproofing effect, Xypex must become an integral part of the concrete mass. It does so by taking advantage of the natural and inherent characteristics of concrete; concrete is both porous (capillary tract system) and chemical in nature.

By means of diffusion, the reactive chemicals in Xypex use water as a migrating medium to enter and travel through the capillary tracts in the concrete. This process precipitates a chemical reaction between Xypex, moisture and the natural chemical by-products of cement hydration (calcium hydroxide, mineral salts, mineral oxides and unhydrated and partially hydrated cement particles).

The result is crystallization and, ultimately, a non-soluble crystalline structure that plugs the pores and capillary tracts of the concrete.

In this condition, the pores become discontinuous and the concrete is thereby rendered impenetrable by water and other liquids from any direction. The Xypex crystalline process will reactivate whenever water is present.
