Sealing Over A GRP To PCCP Transition


June 20th, 2024

Glass reinforced pipe (GRP) had previously been sliplined in a section of a 102” diameter prestressed concrete cylinder pipe (PCCP). HydraTite functioned as a termination seal to fortify this aqueduct’s transition from the 102” PCCP to the 90” GRP. First, strips of EPDM rubber were positioned near the transition, and grout was built up in such a way as to create a gradual transition from the PCCP to the GRP. After the grout was cured, the seal was installed over it. The versatility of the HydraTite seal allowed for installation despite the different diameters between the GRP and PCCP. The transition is now fortified against the formation of leaks.
