How effective is Xypex?
Xypex Crystalline Technology is excellent for reducing the water permeability of concrete and for the healing of leaking, non-moving cracks and joints in concrete structures. Xypex crystals will bridge most non-moving cracks up to 0.4 mm (1/64”).
What is Xypex used for?
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.
Can I paint over Xypex?
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.
What is negative waterproofing?
Negative-side waterproofing is the application of a coating material to the interior or the ‘dry’ side of a foundation or wall. Its primary function is to create a barrier coat to stop water from leaking through the wall and keeping the space dry.
How do you mix Xypex?
Using a trowel, mix one part clean water with six parts Xypex Concentrate powder by volume for 10 – 15 seconds. Lumps should be present in this mixture. Do not mix more than can be applied in 20 minutes.

What is difference between positive and negative side waterproofing?
Positive-side waterproofing by definition is applied to the outside (wet) face of the subsurface building components, by contrast to negative-side waterproofing which is applied to the inside (dry) face of the subsurface building components.
Can Xypex be applied over paint?
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. Yes.
What is the best waterproofing for exterior walls?
ISOMAT FLEXCOAT is the ideal solution for waterproofing of external surfaces against rain. It is a highly elastic, high quality water-soluble paint, based on acrylic elastomeric resins. ISOMAT FLEXCOAT makes walls totally impermeable by rain.
Is Xypex an admixture?
Xypex Bio-San C500 is a uniquely designed admixture for integral, long-term protection of concrete in harsh sewage conditions with high levels of H2S that cause Microbial Induced Corrosion (MIC).
What is bentonite waterproofing?
Bentonite waterproofing is an exterior waterproofing treatment that is supposed to work by forming a barrier between wet soil and the building foundation. Like any type of clay, bentonite absorbs moisture.
