The WrapidSeal Manhole Encapsulation System from CCI Pipeline Systems consists of an engineered primer and a wraparound, heat-shrinkable sleeve designed to seal joints and prevent groundwater from entering a collections system. This material has a high shrink membrane (70% stretch and 40% recovery) designed to shrink around any manhole profile. In addition, the high tensile strength accommodates structural movement, while the tough backing resists soil stress and provides suitable abrasion resistance. It can be used for new construction or for the rehabilitation of existing manholes to control infiltration through joints and prevent deterioration, thus eliminating costly maintenance repairs and the added expense of treating groundwater. 800-867-2772; www.wrapidseal.com.
