Perma-Main™ Top Gun™ Cured-In-Place-Pipe (CIPP) Manhole to Manhole Inversion Rehabilitation System. The Perma-Main™ Top Gun™ lining system is designed for 8" – 24" Diameter Pipelines. The materials are air inverted through existing manholes and steam cured in as little as 1 ½ hours. The Perma-Main™ Top Gun materials can be installed safely, fast, and efficient. Installations average 300FT to 600FT in length. Transitions from 6" – 8" can be accomplished in a single installation. Materials are delivered prewet out, ready for installation. Installation equipment is compact and user friendly.
The Perma-Main™ Air Inversion Liner System allows for the liner to continuously invert through the existing pipeline using low air pressure.
Our compact 750,000 BTU Dry Steam Generators allows the liner to harden without the use of large boiler trucks, in half the time!
The #1 preventative maintenance tool to solve infiltration & inflow. Seal your collection system with a seamlessly molded seal - compatible with all cured-in-place-pipe systems
Seamless molded seal with no joints or weak points preventing any damage or inefficient sealing of the annular space between the liner and the host pipe.
The gasket allows for more swelling than less precise methods of sealing such as hydrophilic tape. The End Seal is able to absorb more water and seal the annular space efficiently because of it’s larger surface area.
Versatile hydrophilic sealing system compatible with all types of CIPP liners including inversion and pull in place liners. The End Seal Sleeve will swell in the presence of water regardless on the type of host pipe.
