Ultra-Grip, produced from high-density polyethylene (HDPE) and polypropylene (PP) is available in thicknesses ranging from 2 mm (80 mil) to 5 mm (200 mil). Ultra-Grip is available in a variety of colors and configurations for both rolls and sheets and is among the widest CPL produced in the United States at 10 feet. But Ultra-Grip’s impressive backpressure resistance is what sets it apart from its competitors. If a corrosion protection system cannot sustain the required backpressure long-term then its failure is imminent. Failure leads to concrete corrosion with high costs associated with replacement, traffic control measures and bypass pumping systems.

Groundwater backpressure also presents a significant concern for wastewater professionals due to its contribution to inflow and infiltration into sewer systems. Allowing other fluids to enter a wastewater treatment system is an unnecessary and costly expense. Therefore, wastewater professionals are compelled to design systems that are limited to only treating wastewater. Ultra-Grip’s tensile strength and high elongation allow it to bridge cracks in concrete structures and prevent groundwater from entering the wastewater system.
