Xypex Resists Aggressive Chemicals
By preventing the penetration of aggressive chemicals, Xypex helps control the problems of sulphate attack, leaching, alkali-aggregate reaction, carbonation, and corrosion.Because Xypex is pH specific (not chemical specific) it will protect concrete from any chemical whose pH range is 3.0 to 11.0 constant contact, or 2.0 to 12.0 periodic contact.

Xypex Resists Extreme Hydrostatic Pressure
Xypex resists extreme hydrostatic pressure from either the positive or negative surface of the concrete slab. Because Xypex is not dependent upon adhesion to the concrete surface and instead becomes an integral part of the concrete mass, it is capable of resisting extreme hydrostatic pressure from either side (positive or negative) of the concrete.

Xypex Protects Against Freeze/Thaw Damage
By blocking the intrusion of water into concrete, Xypex helps protect the concrete from the damaging effect of repeated freeze/thaw cycles.

Xypex Provides Chloride Protection In Marine Environments
Xypex crystalline technology prevents ingress of water, salt solutions and many aggressive chemicals in both new and remedial applications. Xypex permits the concrete to ‘breathe’ out existing moisture vapour whilst excluding the entry of further solutions.

Xypex Protects Reinforcing Steel
By preventing the intrusion of water, salt water, sewage, and most chemicals, Xypex helps protect reinforcing steel against oxidation and deterioration.

Xypex products are suited for both new and existing concrete structures requiring repair or refurbishment. Typical applications of Xypex product in a remedial scenario include crack repair, spalling repair and surface protection or reinstatement with the Xypex coating system. A comprehensive list of schematics are available for concrete remedial repair utilising Xypex concrete waterproofing & durability products. The schematics provide a solution for typical scenarios including pipe penetrations, joint details, crack repair and coatings.

Xypex Admix is part of the Xypex Concrete Waterproofing and Protection System which also includes Xypex Coatings, Dry Shake and Repair products. This total system provides the product flexibility needed to realize the full potential of a Value Engineered concrete waterproofing strategy and the most appropriate and cost effective solution. 

Better Project Control
Using Xypex Admix means that the waterproofing and pouring of concrete occur simultaneously. This means that engineers and contractors can exert much better control over the waterproofing production schedule.

Better Cost Control
Construction schedules can be accelerated and cost savings realized by eliminating most of the time and labor costs associated with traditional waterproofing methods. This makes Xypex Admix less costly to install.

Climate Control
Hot, cold, wet, or dry, the prevailing climate does not inhibit the installation of Xypex Admix. It’s already in the mix. Better control. A better solution.

Xypex Admix is a specialty product that is blended into the concrete at the time of batching. It outperforms other methods because of its unique ability to become a truly integral part of the concrete matrix. Utilizing Xypex’s world-renowned crystalline technology, Xypex Admix seals the primary paths by which water and aggressive chemicals penetrate, attack, and ultimately threaten the long-term integrity of the concrete structure.

Xypex controls permeability which is a key link to greater durability, the long-term structural integrity, protective capacity and aesthetic qualities of the concrete. By preventing the penetration of aggressive chemicals, Xypex Admix C-Series helps control the problems of sulphate attack, leaching, alkaline aggregate reaction, carbonation and chloride induced corrosion.

Yes. There are no adverse effects on mix design.

As an additive, Xypex Admix will not adversely affect the strength, slump, air entrainment or workability of the concrete as formulated in the mix design. With Xypex Admix inside, concrete is still handled, placed, finished and cured as usual. In other words, concrete containing Xypex Admix still behaves like concrete.

When used as a coating, Xypex normally produces a grey-colored, cementitious surface. However, Xypex “White” is also available.

• Achieve greater design flexibility
• Build to LEED standards
• Keep your project on time and on budget

Concrete is one of the strongest elements of both function and form – a key, universal building block in a world that needs its proven versatile qualities. The concrete waterproofing benefits provided by Xypex products have been integral to architectural planning in projects around the world. Architects who have specified it know that Xypex make concrete even better.

Xypex has many advantages over traditional barrier and membrane systems plus Xypex Crystalline Technology is unique. You will find superior product and application flexibility. As a coating, dry-shake or admix; brushed on, poured-in-place, shotcrete or precast, or concrete repairs – Xypex is easy to use. Using Xypex ensures satisfaction in what you are doing – confidence in every job.

Most cementitious coatings are simply surface treatments and are totally dependent on maintaining a proper bond to the concrete surface. Such coatings usually incorporate a latex modifier which makes the coating less permeable and acts as a bonding agent for better adhesion to the surface. They are surface treatments only, and have the added disadvantage of limiting breathability of the concrete. They do not form crystals within the concrete substrate (contrary to what is sometimes represented) and are not effective when applied against hydrostatic pressure.

Yes. In most circumstances paint, epoxy coatings, cement parge coats, plaster and stucco can be applied over a Xypex coating. For further information concerning the interface of the Xypex coating with paint and other finishing materials, consult with a Xypex Technical Services Representative.

Xypex is totally compatible with the chemistry of concrete, whether cast-in-place, precast or shotcrete. It is not suitable for application to cut-limestone, clay brick, wood, metals, asphalt or other non-concrete building materials.

Yes. In fact, the concrete must be wet or moist before applying the Xypex slurry coat. Xypex requires moisture to generate the crystalline growth in concrete. The presence of moisture is also necessary to ensure proper bonding of the slurry coat to the concrete substrate.

Generally, it is recommended that the Xypex coating be applied to the positive side (water side), if accessible, so as to ensure maximum benefit. Therefore, new construction specifications almost always call for the use of the Xypex coating on the positive side (water side). If, however, the positive side is not accessible e.g. tunneling projects or rehabilitation of existing structures, the Xypex coating will be specified for use on the negative side against the hydrostatic pressure.

Yes. Although applied as a coating, Xypex is not relying on its surface bonding capability to achieve its waterproofing effect. By means of diffusion, the reactive chemicals in the Xypex coating migrate through the capillary tracts within the concrete to become an integral part of the concrete mass. Therefore, the Xypex coating can be applied to either the positive (water side) or negative side even against strong hydrostatic pressure.

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 0.4 mm (1/64”).
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. 

Typical Xypex applications include reservoirs, sewage and water treatment tanks, secondary containment structures, tunnels, underground vaults, manholes, concrete pipe, foundations, pools, parking structures and below grade construction.

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.
