The Xypex crystalline system for concrete protection is substantially different from traditional barrier products — like membranes and cementitious coatings. Check these differences:

• Xypex creates a crystalline structure deep within the pores and capillary tracts of the concrete mass to prevent the penetration of water and aggressive chemicals. In contrast, barrier-type products function only at the surface of the concrete.
• Because Xypex is not dependent on surface adhesion to achieve its concrete protection effect, it is resistant to extreme hydrostatic pressure.
• It will seal hairline cracks up to 0.5 mm.
• It is not subject to the deterioration problems encountered by membranes.
• Xypex is permanent and reactivates whenever water is present.

The crystalline nature of the Xypex concrete protection system provides many application advantages over traditional barrier products.

• Xypex does not require a dry surface; in fact, a wet surface is necessary.
• Xypex does not require dry weather to be applied.
• Xypex does not require costly surface priming or leveling prior to application.
• It cannot puncture, tear, or come apart at the seams.
• It does not require protection during backfilling or during placement of steel, wire mesh or other materials.
• It can be applied on either side of a concrete surface — the negative or the positive (water pressure) side. Seams at corners, edges or between membranes.
• It is less costly to apply than most other methods.
