Why Xypex?

Xypex technology

Xypex is a non-toxic chemical treatment for the waterproofing and protection of concrete.

Xypex has a unique ability to generate a non-soluble crystalline formation. This primary and most distinguishing performance feature creates a crystalline structure within the pores and capillary tracts of the concrete permanently sealing the concrete against the penetration of water and other liquids from any direction.

Xypex crystalline products are dry powder compounds composed of Portland cement, silica sand and many active proprietary chemicals.

Basic to the development of Xypex Crystalline Technology was a thorough understanding of concrete's chemical and physical makeup. Concrete is porous. Its tunnel-like capillaries are a natural part of its mass and permit the passage of water and other liquids. Researchers at Xypex recognised the opportunity for a chemical treatment that would fill these capillaries to prevent the penetration of water and other liquids from any direction. By means of diffusion, the reactive chemicals in Xypex products use water as a migrating medium to enter and travel down the capillaries of the concrete. This process precipitates a chemical reaction between Xypex, moisture and the by-products of cement hydration, forming a new non-soluble crystalline structure. This integral structure fills the capillary tracts rendering the concrete waterproof.

Xypex Crystalline Technology is now specified and used on thousands of diverse waterproofing projects around the globe. Crystalline waterproofing technology was an idea that developed because Xypex chemists questioned what concrete was all about and found a way to make it better. Today, we continue the tradition.
