Xypex Chemical Corporation
Vancouver, Canada is home to the head office and manufacturing facility of Xypex Chemical Corporation. The Xypex crystalline technology for waterproofing, protecting and enhancing concrete was conceived and developed in 1969. Since then, our technology has been tested and proven worldwide in all climates and in widely varying construction situations. Today, in over 65 countries, Xypex is specified and applied on thousands of major concrete structures around the world. The Xypex crystalline waterproofing system is uniquely effective and long-lasting because it becomes an integral part of the concrete itself.
What is Xypex?
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 the permanently seals the concrete against the penetration of water and other liquids from any direction. It is a dry powder compounds composed of Portland cement, Silica sand and many active, proprietary chemicals.
How Dose Xypex Work?
To create its crystalline waterproofing effect, Xypex must become an integral part of the concrete mass. It dose so by taking advantage of the natural and inherent characteristics of concrete; concrete is both porous (capillary tract system) and chemical in nature. By means of diffusion, the reactive chemicals in Xypex use water as a migrating medium to enter and travel through the capillary tracts in the concrete. This process precipitates a chemical reaction between Xypex, moisture and the natural chemical by-products of cement hydration (calcium hydroxide, mineral salts, mineral oxides and un-hydrated and partially hydrated cement particles). The result is crystallization and ultimately a non-soluble crystalline structure that plugs the pores and capillary tracts of the concrete. In this condition the pores become discontinuous and the concrete is thereby rendered impenetrable by water and other liquids from any direction.
How Waterproof is Xypex - Treated Concrete?
A major independent testing laboratory performed concrete waterproofing tests on Xypex in accordance with Army Corps permeability Specification CRD-C48-73. the results showed that a two coat application of Xypex on 50 mm thick 13.8 MPa porous concrete totally eliminates leakage at pressures of at least 123.4m of head pressure (1.2 MPa), the limit of the testing apparatus.
How Dose The Xypex Crystalline Formation Penetrates The Concrete?
The Xypex Chemical reactions that initially take pace at the concrete surface or immediately adjacent area will continue deep into the concrete structure. Independent testing measured the depth of Xypex crystalline penetration into a cast-in-place concrete block at 30cm.
How Long Dose Xypex Last?
A Xypex application is permanent. Its unique, dendritic, crystalline growth wills not deteriorate under normal conditions.
How Resistant is Xypex To Aggressive Chemical?
Based on independent testing according to ASTM C 267-77 "chemical Resistance of Mortars", Xypex is not affected by a wide range of aggressive chemicals including mild acids, solvents, chlorides and caustic materials.
Dose Xypex Protect Reinforcing Steel?
Yes, By preventing the intrusion of chemical, salt water, sewage and other harmful materials, Xypex protects concrete and reinforcing steel from deterioration and oxidation
Is Xypex Toxic?
No, Xypex contains no volatile organic carries (VOC) and can be applies safely in enclosed surroundings. Xypex is approved by numerous country and state health and waterworks departments for use on structures, which contain potable water or foodstuffs.
Can Xypex Be Applied Against Extreme Hydrostatic Pressure?
Yes, Because Xypex is not dependent upon adhesion to the concrete surface and instead becomes an integral part of the concrete mass through crystallization; it is capable of resisting extreme hydrostatic pressure from either side (positive or negative) of the concrete.
Can Xypex Be Applied While The Concrete is Wet?
Yes, In fact, the concrete must be wet or moist before applying the Xypex slurry coat.
Is Xypex Used To Waterproof Cracks, Joints & Other Defects In Concrete?
Yes, Xypex has a specific repair system that utilizes its unique crystalline waterproofing technology to stop water flow trough cracks, faulty joints and other defects.
What is The Appearance of A Xypex Coating?
A Xypex coating produces a grey-colored, cementations surface.
Can Paint & Other Materials Be Applied Over A Xypex Coating?
Yes, paint, epoxy coatings, cement purge coats, plaster and stucco can be applied of installed over a Xypex coating.
How is Xypex Different From Other Products?
The Xypex crystalline system for concrete waterproofing is substantially different traditional barrier
Products (membranes cementations coatings):
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.
2. Xypex is not dependent on surface adhesion to achieve its water proofing effect; it is resistant to extreme hydrostatic pressure.
3. Xypex will seal hairline cracks up to 0.4 mm.
4. Xypex is not subject to the deterioration problems encountered by membranes.
5. Xypex is permanent and reactivates whenever water is present.
What are The Application Advantages of Using Xypex Instead of Membranes?
1. Xypex dose not require a dry surface; in fact, a wet surface is necessary.
2. Xypex dose not require dry weather to be applied.
3. Xypex dose not require costly surface printing or leveling prior to application.
4. Xypex cannot puncture, tear or come apart at the seams.
5. Xypex cannot require protection during backfilling or during placement of steel, wire mesh or other materials.
6. Xypex can be applied on either side of a concrete surface - the negative or the positive (water pressure) side.
7. Xypex dose not require sealing, lapping and finishing of seams at corners, edges or between members.
8. Xypex is less costly to apply than most other methods.

Xypex Product Descriptions
Xypex concentrate: is the most chemically active of the xypex waterproofing products. When mixed with water, this light grey powder is applied as a 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 sealing strips at construction joints, or for the repairing of cracks, faulty construction joints and honeycombs.
Xypex modified: xypex Modified can be applied as a second coat to reinforce Xypex Concentrate or by itself to damp-proof the exterior of foundation walls. Modified produces a harder finish and speeds the curing of the Concentrate. Where damp proofing is required, a single coat of Modified may be used as an alternative to a spray/try emulsion.
Xypex Admix: With the Admix C Series, Xypex's unique crystalline dry powder compound for the waterproofing, protection and improvement of concrete is added to the concrete mix at time of batching.
Xypex Patch'n Plug: Xypex Patch'n Plug is formulated as a crystalline, fast setting, non-shrink, high-bond-strength, and hydraulic cement compound for concrete repairs. It stops flowing water in seconds and is used to seal cracks, fill tie-holes and other defects in concrete.
Xypex Restora-Top: Xypex Restora-Top products are designed specifically for warehouse floors, bridge decks, roads, curbs and walkways where the repaired are must be returned to normal service within two hours of the completed repair.
