Pipe Rehabilitation

Pipe Rehabilitation Materials Testing

Rehabilitation of piping systems is a specialized profession in which collapsed or corroded pipe can be relined or reinforced with new types of polymers. The ever-growing proliferation of materials, systems, and techniques demands the most of designers, specifiers, installers, and inspectors. Microbac provides services to all of these user groups to ensure that pipe rehabilitation liners meet specific quality, performance, and compliance standards.

Trenchless Pipe Rehabilitation Technology

Many of today’s pipe rehabilitation methods revolve around trenchless pipe installation. Trenchless pipe rehabilitation saves time, money, and resources, helping preserve sections of the pipe that may still be salvageable.

One of the most common products in the pipeline rehabilitation industry is cured in place thermosetting pipe (CIPP).  CIPP is a trenchless technique in which a new liner is formed inside an existing pipeline to repair pitting, internal corrosion, erosion and general degradation.  In this process with a thermosetting resin is inserted into the host pipe and then expanded and cured to form a tight fitting pipe within a pipe.

This technique is applicable for trenchless sewer repair, trenchless water line repair, and trenchless sewer line replacement. There are several types of resin, including polyester (sewer pipe), vinyl ester (industrial and special waste pipe) and epoxy (potable water and pressure pipe).
