Insignia Hydrophilic Compression Gaskets

There are many misconceptions about CIPP linings and water migration. Although the myth that CIPP linings bond to the host pipe has largely been discredited, it is still not commonly known that due to the physical properties of thermo-set resins, CIPP liners shrink during polymerization resulting in an annular space between the liner and the host pipe. This annular space allows groundwater to track behind the liner and migrate back into the collection system causing not only a significant amount of avoidable wastewater treatment, but also sanitary sewer overflows (SSOs) and potential groundwater contamination if a seal in the collection system is breached.

In order to seal these connections and ensure a structural and watertight repair, we offer several hydrophilic sealing solutions based on the type of trenchless repair and the method of installation.
