3M Scotchkote Pipe Renewal Liner 2400 helps provide a cost effective solution to many of the problems common to potable water distribution systems. Its unique properties, combined with a trenchless spin cast application process, can efficiently coat the existing infrastructure restoring internal pipe diameters, increasing flow, improving efficiency, minimizing water loss and helping to prevent additional corrosion and build-up of scale and tuberculation. At prescribed lining thickness (caliper) and bury depths, Scotchkote Liner 2400 is projected to meet the material properties of ASTM F1216-09 after 50 years. Scotchkote Liner 2400 offers a 10 minute set time and 60 minute cure followed by a 30 minute flush. The ability to reinstate a water main within 90 minutes of lining allows for same day return to service. 888.745.4350, 3M.com

Standard Cement Materials

Use Reliner MSP cement, pure fused calcium aluminates and EPA verified epoxy coatings for rehabilitating existing manholes, horizontal sewerage pipes and bends, and corrugated metal pipe culverts (CMP) to 120 inches using high strength, “cast-in-place” cement liner technology. This repair system is comprised of a one-component structural cement mortar liner or the cement liner and a subsequent epoxy coating system. These materials work together as a non-destructive repair process to restore structural integrity, stop water infiltration and to protect the manhole against microbial induced corrosion and chemical attack. 888.278.1337, standardcement.com
