CIM Industrial Membrane Systems form continuous elastomeric barriers to water and most chemical solutions. Two liquid components are mixed on a job site just prior to cold application by squeegee, roller or spray and the liquid cures quickly to form a seamless asphalt-extended polyurethane membrane with tremendous strength and flexibility. Developed by Chevron in the early 1970's, these remarkable materials are manufactured by C.I.M. Industries Inc. in the original facilities.
