What is Xypex?

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

Its primary and most distinguishing performance feature is its unique ability to generate a non-soluble crystalline formation deep within the pores and capillary tracts of the concrete; a crystalline structure that permanently seals 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.

Why is Xypex unique?

Xypex is a unique chemical treatment for the waterproofing, protection and enhancement of concrete.

Xypex products contain many active proprietary chemicals. These active chemicals react with the moisture in concrete and with the by-products of cement hydration to cause a catalytic reaction.

This unique reaction generates a non-soluble crystalline formation throughout the pores and capillary tracts of the concrete that permanently seals the concrete and prevents the penetration of water and other liquids from any direction. It can also self-heal cracks up to 0.4mm.

Application of Xypex

New Build
Because Xypex becomes an integral part of the concrete substrate, it is uniquely effective and permanent, ensuring protection is maintained for the life of the concrete.

Retrospective Applications
Xypex also offers a range of crystalline products that are designed specifically to be applied as a surface coating to cured concrete and other substrates i.e. block work/masonry, to give a totally waterproof environment. These products are designed for use even when there is a hydrostatic head of pressure.
