Why use Gasket Sealing Technology?
Did you know that after a CIPP liner is installed groundwater can re-enter your wastewater collection system?
Shrinkage can occur in all CIPP liners
When this happens it allows groundwater to enter the space between the host pipe and the new liner. This water will then migrate to the end of the pipe and/or to a connection point where it will re-enter the wastewater collection system.
ASTM F3240 Standard Practice for Installation of Seamless Molded Hydrophilic Gaskets (SMHG) for Long-Term Watertightness of Cured-in-Place Rehabilitation of Main and Lateral Pipelines
This ASTM Standard was developed in order to address this type of infiltration.
Hydrophilic Gasket Seals
In order to seal these connections and ensure a structural and watertight repair, there are several hydrophilic sealing solutions that comply with ASTM F3240.
