XYPEX CONCENTRATE (60 LBS)

Xypex

Part # CON-060

Xypex Concentrate is the most chemically active product within the Xypex Crystalline Waterproofing System. When mixed with water, this light grey powder is applied as a cementitious slurry coat to above-grade or below-grade concrete, either as a single coat or as the first of a two-coat application. It is also mixed in Dry-Pac form for sealing strips at construction joints, or for the repairing of cracks, faulty construction joints and honeycombs. Xypex prevents the penetration of water and other liquids from any direction by causing a catalytic reaction that produces a non-soluble crystalline formation within the pores and capillary tracts of concrete and cement-based materials.


Description

Product Information & Usage

Xypex is a non-toxic, chemical treatment for the waterproofing and protection of concrete. Xypex's primary and most distinguishing performance feature is its unique ability to generate a non-soluble crystalline formation deep within the pores and capillary tracts of the concrete - a crystalline structure that permanently seals the concrete against the penetration of water and other liquids from any direction. Xypex crystalline products are dry powder compounds composed of portland cement, silica sand and many active, proprietary chemicals.

Features and Benefits

The crystalline nature of the Xypex waterproofing 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.
  • Xypex does not require sealing, lapping and finishing of seams at corners, edges or between membranes.
  • It is less costly to apply than most other methods.
  • 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 waterproofing effect, it is resistant to extreme hydrostatic pressure.
  • It will seal hairline cracks up to 0.4 mm.
  • It is not subject to the deterioration problems encountered by membranes.
  • Xypex is permanent and reactivates whenever water is present.

Applications

  • Reservoirs
  • Sewage and Water Treatment Plants
  • Underground Vaults
  • Secondary Containment Structures
  • Foundations
  • Tunnels and Subway Systems
  • Swimming Pools
  • Parking Structures

Composition and Materials

Xypex is manufactured in the form of a dry powder compound consisting of portland cement, very fine treated silica sand and various active proprietary chemicals.

When mixed with water and applied as a cementitious coating, the active chemicals in Xypex cause a catalytic reaction which generates a nonsoluble crystalline formation of dendritic fibers within the pores and capillary tracts of concrete. Thus, the concrete itself becomes permanently sealed against the penetration of water or liquids from any direction.

Limitations

Xypex products must be stored dry at a minimum temperature of 45°F (7°C). The shelf life is one year when stored under proper conditions.

Xypex is not designed for use in expansion joints or chronically moving cracks.
