Xypex Chemical Corporation manufactures a line of products used to waterproof a wide range of concrete structures: foundation walls and floors, retaining walls, water tanks, water and sewage treatment plants, tunnels, manholes, and marine structures. Xypex has been tested and proven worldwide in all climates and in widely varying construction situations. Today, through an international network of distributors and licensees in over 70 countries, XYPEX is specified on thousands of major concrete structures around the world.
Xypex takes advantage of the natural porous and chemical characteristics of concrete to precipitate a chemical reaction with the moisture and the natural chemical by-products of cement hydration. The result is a non-soluble crystalline structure that plugs the pores, capillary tracts and micro-cracks in the concrete. In this condition, the concrete becomes impenetrable by water and other liquids from any direction.
Because Xypex becomes an integral part of the internal concrete structure, the advantages are numerous: Xypex cannot puncture, tear or come apart at the seams; it does not require protection during backfilling; seals hairline cracks up to 0.4mm; does not require costly surface priming or leveling and is less costly to apply than most other methods.
Xypex Crystalline Waterproofing is available as a coating, dry-shake (for new slab construction) or as an admixture. This product mix gives the architect and contractor the flexibility to use the most appropriate method for their particular application.
