The Permanent Solution

Xypex Crystalline Technology

Xypex products use the natural porosity of concrete and chemical diffusion to penetrate its pores and capillaries. Inside the concrete, Xypex chemicals react with un-hydrated cement particles and the by-products of cement hydration to form a non-soluble crystalline structure deep within the substrate. In this condition, the concrete becomes impermeable, preventing the penetration of liquids and chemicals from any direction even under extreme hydrostatic pressure. The chemical resistant properties of the crystalline structure will help mitigate the attack of sulphates and chlorides. In prolonging the durability of concrete, Xypex has also proven to be effective against the damaging effects of Alkali Aggregate Reaction as well as having the ability to self-heal static cracks up to 0.5 mm (0.02 in). Xypex also improves the freeze-thaw durability of concrete.


The Xypex Advantage

Xypex Crystalline Technology works inside the concrete, thereby avoiding the problems typical of traditional barrier products.

  • Permanent and reactivates whenever water is present
  • May be applied on negative or positive side of concrete surface
  • Self-heals static cracks up to 0.5 mm (0.02 in)
  • Not subject to deterioration problems encountered by surface coatings and membranes
  • Requires no additional protection as with preformed membranes
  • Resistant to chemical attack (AAR)

Proven Performance Worldwide

Comprehensive quality systems and standards along with thorough testing in the lab and the field have resulted in Xypex’s highly respected position in the concrete industry. Xypex has been extensively tested by independent testing laboratories in the U.S., Canada, Australia, Japan, Europe and other countries.
