Description

Crystalline waterproofing coating is a surface-applied cementitious slurry that creates an integral waterproofing system by penetrating into concrete substrates. When applied at 1.0-2.0mm thickness, the active chemicals react with moisture and cement hydration by-products to generate non-soluble crystalline formations within concrete pores and capillaries, providing permanent protection against water ingress even under high hydrostatic pressure.

Advantages
Permanent waterproofing solution - lifetime of concreteSelf-healing capability for cracks up to 0.4mmResists extreme hydrostatic pressure (positive/negative)Becomes integral part of concrete structureNSF 61 approved for potable water contactBreathable - allows vapour transmissionChemical resistant to pH 3-11No surface preparation for negative side applicationIncreases concrete durability and lifespanNon-toxic and environmentally safe
Cautions
Requires saturated surface dry (SSD) substrateCannot bridge structural cracks >0.4mmMinimum 7-day concrete cure before applicationTemperature sensitive during application (5-35°C)Requires protection from rain for 24-48 hoursProfessional application recommendedNot suitable for non-cementitious substratesMay show efflorescence initiallyRequires CSP-4 surface profile for optimal performance

Crystalline waterproofing technology was developed in the 1940s and commercialized in the 1960s. First introduced to Australia in the 1980s, it has become a standard specification for water-retaining structures and infrastructure projects. Major suppliers in Australia include Xypex (Canada), Penetron (USA), and local manufacturers producing under license. The technology has evolved from basic crystalline formulations to advanced systems with enhanced self-healing properties and chemical resistance.
