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.
