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. 

Insignia End Seal Sleeve

Seamlessly molded to provide a large 360 ° sealing surface. It will allow for more swelling than less precise sealing methods such as hydrophilic tape, rope or paste. 

Compatible with Multiple Types of CIPP

Insignia O-Rings

Once exposed to water, they can swell up to 5 times their original size to create the compression gasket.

Available up to an 8" diameter and is mainly used for lateral lining or spot repairs

Specifier's Guide to Mainline Sealing

Since CIPP liners do not  bond with the host pipe, they inherently do not address the infiltration of groundwater into the wastewater collection system. 
Learn more about how to guarantee your project eliminates the I&I.
