InnerSeal System - Installation Process

A pre-manufactured, needle punched felt liner material made to match the geometry of the service connection is impregnated with a two-part 100% solids epoxy resin. The InnerSeal liner material is then positioned inside the carrier train exposing the InnerSeal connection brim.

 

A winch pulls the train through the mainline to the service connection to be repaired. An articulating robot precisely aligns the main bladder opening so that it is directly facing the service connection.

 

Air pressure pushes the InnerSeal into the service connection. The InnerSeal liner is inverted from the mainline into the service connection. The specially formulated resin is allowed to cure without adding heat.

 

The inversion bladder is deflated and the positioning tool removed from the main line. Repair of the defective connection is complete. The process results in a watertight service connection seal and a structurally sound, solid connection with a minimum life expectancy of 50 years.

 

The strength, life expectancy, chemical resistance and non-disruptive installation characteristics of CIPP have revolutionized the pipe rehabilitation industry. After 25 years in the market, it remains the preferred method for trenchless repair of municipal sanitary and storm sewer lines as well as industrial sewer and product lines.

InnerSeal System - Equipment

Insta-Pipe has an easy and non-intrusive way to correct Lateral Pipeline and Main Line Sewer Pipeline connection problems.

The InnerSeal™ Lateral Connection is a quality product for the rehabilitation of the lateral to mainline connection point. The unique materials are designed to be placed from within the main sewer pipeline and launched into the lateral creating a water tight seal at the main / lateral connection point. The lateral is also lined at the same time correcting any damaged pipe sections and preventing roots from growing into the pipeline.

The InnerSeal™ resin technology is 100% solids epoxy. This resin formulation is ambient cure and can be modified for hot water or steam curing. The ambient cure formulation has excellent bonding properties in all pipe materials and does not contain styrene. Our Epoxy resin does not shrink and will seal off water infiltration during the application.

The InnerSeal™ Connection System can rehabilitate from 6” to 24” sewer mains with 3” to 8” lateral tye-ins. This system allows us to provide a structural liner connection with 22’s, 45’s and 90 degree connections.

The InnerSeal™ installation is controlled from the operator’s station inside the enclosed trailer system. The operator can control the direction of the repair train and position the train into the lateral connection. The operator’s station also allows full control of the inversion pressure in order to secure the liner properly against the host pipelines.
