Sure-Grip concrete liners from Agru America extend the life of tanks, pipes and other structures by combining the flexibility and chemical resistance of thermoplastics with the strength of concrete. It is ideal for new cast-in-place construction, rehabilitation projects and prefabricated elements such as concrete pipes and manholes. Its V-shaped 13 mm tall Ultra Grip anchors are designed for concrete structures subject to high groundwater backpressure, and Sure-Grip with 19 mm tall anchors is designed for rehabilitation of structures where a thicker layer of grout is required. It is available in a variety of resins (including HDPE, PP, PVDF and ECTFE), thicknesses and sheet/roll dimensions, and with an anti-skid surface for floors, a coextruded signal layer for damage detection and a self-cleaning surface for reduced sedimentation in pipe inverts. 800/373-2478; www.agruamerica.com.
