Xypex Concentrate

Penetrative crystalline cementitious slurry waterproofing coating

$17-24/m2 (per coat)

Coverage: 0.65 - 0.8 kg/m2 (per coat)

Xypex is a unique chemical treatment for the waterproofing, protection and repair of concrete. XYPEX CONCENTRATE consists of Portland cement, finely graded sand and active proprietary chemicals; it is applied as a cementitious slurry to the pre-saturated surface of existing above and below grade structures. The active chemicals diffuse into the substrate and react with moisture and the constituents of hardened concrete to cause a catalytic reaction. This reaction generates a non-soluble crystalline formation throughout the pores and capillary tracts of the concrete, as well as cracks, permanently sealing the concrete and preventing the penetration of water and other liquids from any direction, even under high hydrostatic pressure. Xypex Concentrate is also mixed in a Dry-Pac form for sealing strips at construction joints, or for the repairing of leaking cracks, faulty construction joints and other defects.

    Technical

    Water Permeability: >124 m head (US Army Corps of Engineers CRD C48-92)
    Water Impermeability of Concrete: 4 mm (DIN 1048)
    Depth of Water Penetration: < 1 mm (EN 12390-8)
    Tensile Bond Strength: 1.23 MPa (EN 1542)
    Chemical Resistance to Mortars: One-eighth of the erosion of reference samples (ASTM C 267)
    ASTM C856 “Standard Practice for Petrographic Examination of Hardened Concrete”: In each case, there was evidence of the Xypex crystalline structure in the cracks to a depth of about 20 mm. Photographs taken this depth at 100x magnification showed the Xypex crystalline structure had reduced the width of the cracks dramatically.
    RILEM CPC-18 “Carbonation Resistance of Samples Treated with a Xypex Concentrate Coating”: 35-40% less than reference samples.
    ASTM C876 “Influence of Xypex Coating System on Residual Service Life of Concrete Structures” Durability Assessment Section, Xypex Australia: Results indicated a reduction of corrosion rate and corrosion potential up to 50% and 40% respectively, and significant enhancement of the concrete resistivity.
    ASTM C 672, “Standard Test Method for Scaling Resistance of Concrete Surfaces Exposed to De-Icing Chemicals”: Visual examination of untreated panels after 50 freeze/thaw cycles showed a marked increase in surface deterioration.
    NSF 61, “Drinking Water System Component-Health Effects”: Exposure testing of potable water in contact with Xypextreated samples indicated no harmful effects
    U.S.A. Standard No. N69, “Protective Coatings for the Nuclear Industry”: After exposure to 5.76 x 104 rads of gamma radiation, the Xypex treatment revealed no ill effects or damages.
