Product Description Xypex Modified can be applied as a second coat to reinforce Xypex Concentrate, or applied by itself to dampproof the exterior of foundation walls. Applied as a second coat, Xypex Modified chemically reinforces Xypex Concentrate where two coats are required and produces a harder finish. Where dampproofing is required, a single coat of Modified may be used as an alternative to a spray/tar emulsion. 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. Advantages Resists extreme hydrostatic pressure Becomes an integral part of the substrate Allows concrete to breathe Resistant to aggressive chemicals Non-toxic Does not require dry weather or a dry surface Cannot puncture, tear or come apart at the seams No costly surface priming or leveling prior to application Does not require sealing, lapping and finishing of seams at corners, edges or between membranes Can be applied to the positive or the negative side of the concrete surface Does not require protection during backfilling or during placement of steel, wire mesh or other materials Less costly to apply than most other methods Not subject to deterioration Permanent
