AP/M Permaform
COR+ROC Epoxy Mortar is a two-component epoxy-based polymer liner, which adheres well to clean, damp surfaces typical of well-prepared manholes. It is applied through Permaform’s bi-directional spincaster for uniform, thorough coverage for reinforcement and chemical corrosion protection. The epoxy can be applied in one application or troweled to any design thickness up to 1-inch thick. With set times of 30-45 minutes, applicators and inspectors have ample time to easily verify the proper thickness with a wet gauge. Ultimate strength values are comparable. 800.662.6465,
