The Xypex crystalline system for concrete waterproofing and protection is substantially different from traditional barrier products (membranes, cementitious coatings, etc):

1. 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 concrete.

2. Xypex will seal hairline cracks up to 0.5 mm (0.02 in).

3. Xypex is not subject to the deterioration problems encountered by membranes.

4. Xypex is designed to be permanent and reactivates whenever water is present.

The Xypex treatment, unlike most other systems, becomes a permanent part of the concrete matrix. Its unique dendritic crystalline growth will not deteriorate under normal conditions, and the crystalline process will reactivate whenever water is present.

Is Xypex used to waterproof cracks, faulty joints and other defects in concrete?

Yes. Xypex has a specific repair system that utilizes its unique crystalline waterproofing technology to stop water flow through cracks, faulty construction joints and other defects. In the case of expansion joints or chronic moving cracks, a flexible sealant is recommended.

Xypex becomes an integral part of the concrete mass itself. Traditional barrier products, on the other hand, rely solely on their performance at the surface of the concrete and are therefore subject to deterioration caused by exposure to the environment, hydrostatic pressure, puncturing, delamination, chemical erosion, and damage during backfilling. Xypex was developed to eliminate these very issues. The Xypex formula is based on the natural characteristics of concrete - the fact that concrete is both porous and chemical in nature. With moisture as the catalyst, Xypex's proprietary chemicals react with the products of cement hydration to form a non-soluble complex within the pores, voids and capillary tracts of the concrete mass. From this inside position, Xypex renders the concrete impenetrable by water and other liquids from any direction, eliminates the problems normally associated with traditional barriers and, in the process, enhances the quality and durability of the concrete structure.

Curtain or Bladder injections refers to chemical injection that is used on block, brick, stone and concrete substrates where the applicator observes large area below grade moisture intrusion and wetness through the entire substrate opposed to intrusion through a specific crack and/or joint.

Because of the immense costs associated with excavation and application of a new positive side membrane, the Curtain or Bladder injection method is an economically viable solution for repair. By drilling a grid pattern of holes the entire way through the substrate, applicators can repair the failed membrane from the inside of the structure.
