Rehabilitation

There are many levels of rehabilitation. As a complete solution provider, VisuSewer will first evaluate conditions and then recommend the best course of action for rehabilitation or repair.

Injection grouting stops leaks at the three most critical points of entry: mainline joints, manholes and service connections. The least expensive “first line of defense” in the battle against infiltration into sewer systems, grouting stops leaks within minutes of application, for long-lasting repairs. The grout is forced into the surrounding soil, creating a waterproof mass that cannot be extruded back into the sewer system. The watertight collar adheres to the outer surface of the pipe, where it will remain indefinitely. Learn more about the materials used.

CIPP (Cured-in-Place Pipe) – This process rehabilitates pipes by installing a new, fully structural National Liner CIPP inside the host pipe from above ground. The new pipe “inside the old pipe” will provide maximum strength and flow capacity without the need for digging. The liner may be custom-designed to meet your unique requirements in strength, wall thickness, bends and chemical resistance. Learn more about the materials used.

Sectional CIPP – When pipe defects are isolated to a couple of locations, Sectional Lining may be the smart financial choice. This trenchless spot repair process is a method of installing a short section of fully structural CIPP to reinforce specific defect locations. The new section of CIPP may be custom-designed to meet your requirements for strength and wall thickness, and can accommodate 8” to 24” pipe diameters. Available lengths will depend on pipe diameter. Learn more about the materials used.

Cementitious Lining – This is a specially formulated, fiber-reinforced cementitious mixture designed for rehabilitating corrugated metal pipe, culverts, concrete pipe, catch basins and other stormwater structures. Strong Seal® is centrifugally cast and can accommodate 24” to 60” pipe diameters. It may also be sprayed manually or troweled in structures or larger diameter pipe sections. Learn more about the materials used.

Cementitious Lining – The Strong Seal manhole rehabilitation system completely rehabilitates and provides a new manhole tightly bound within the existing structure. The resulting half-inch- to one-inch-thick monolithic liner is fully structural, and the cementitious, high-strength mortar is hand-sprayed and trowel-finished to ensure proper coverage. Learn more about the materials used. 

Raven Epoxy and Lining – The Raven epoxy manhole and lift station rehabilitation system has a 30-year track record of protecting below-ground structures from hydrogen sulfide attack. Raven epoxies eliminate infiltration, provide an exceptional bond to moisture-filled substrates and result in a complete structural enhancement with an ultra-high build thickness. Learn more about the materials used. 

CIPM – Triplex is a leading cured-in-place manhole (CIPM) lining method for the permanent rehabilitation of sewer collection systems that are failing due to chemical corrosion and infiltration of groundwater. The patented lining system is constructed with three layers, including fiberglass and an epoxy system that contains a vital, nonporous internal PVC membrane. The process uses the existing structure as a mold, enabling installation without the need for excavation and prolonged sewage flow and traffic disruption. Learn more about the materials used.
