Structural Waterproofing & Envelope Protection
Complete protective envelopes. Seal foundations, pools, wet areas, and flat roofs with crystalline and polymer membrane solutions.
Engineering Overview & Performance Capabilities
Water penetration is the foremost contributor to concrete rebar corrosion and structural degradation. CRO CHEM waterproofing engineering systems deliver continuous, seamless barrier technology, combining two-component elastomeric cementitious coatings, crystalline capillary waterproofing, and flexible joint sealants to resist high hydrostatic head pressure.
Technical System Methodology
From subterranean basements to open podiums and exposed roofs, our elastomeric membranes bridge structural micro-fissures and prevent efflorescence. Certified for potable water containment as well as wastewater and saline ground conditions.
