Our TOP HAT system uses a Polyester impregnated corrosion resistant fiberglass insert. It can reach 8” into the lateral and creates a 3” “brim” in the main pipe. The Epoxy component achieves superior sealing on wet surfaces. This system is capable of covering 6″ to 20” main pipes and 4″ and 6” laterals.
The unique fiberglass insert fits T or Y connections. It is delivered impregnated and wrapped in protective black foil. Installation is easy! The laminate is placed on the applicator, driven to the opening and inserted by air pressure. UV light cured in about 7 minutes
