Which C.I.M. Waterproofing Membrane Is Right for Your Application?
Chevron raised the standards on cold fluid-applied waterproofing membrane applications when they introduced a urethane coating system for synthetic running tracks in the 1960s. Over several decades, this urethane technology morphed into a waterproof bridge deck membrane, now widely recognized as Chase Industrial Membranes (C.I.M. Industries), the leader in the industrial waterproofing market.
Today, six different products represent the C.I.M. line. While all six feature the same technology as the original coating, they have been formulated with key differences to meet various jobsite application requirements. The significant differences are in some of the material's physical properties, such as differing viscosities and material flow properties better suited in vertical and overhead applications, tighter specifications to meet industry approvals, certifications to adhere to NSF61/ANSI specifications for potable water applications, and additional chemical resistivity for harsh secondary containment areas.
The robust characteristics of urethane coatings make them appealing to architects and engineers who seek to specify high-quality, long-term, high-performance waterproofing systems. The features and benefits of C.I.M. are not limited to the membrane's rugged, durable, and resilient performance in abrasive environments. The product's flexibility and elastomeric properties are demonstrated by 400% elongation and its ability to bridge cracks in concrete up to 1/4 inch (6 mm). A low permeability rating of 0.03 perms sets C.I.M apart from other urethane systems.
