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 unhydrated 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 mitigate the attack of sulphates and chlorides that may be present in subsoils and waters.


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

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.
