Economical, trenchless, and allowing for upsizing of existing lines, pipe bursting is a common industry choice for replacing sewer and water pipes while keeping disruptions to city streets, businesses and nearby properties to a minimum.
First developed in Europe to replace cast-iron gas distribution pipe with minimum impact, pipe bursting has been used in the U.S. since 1986 and accounts for the rehabilitation of more than one million linear feet of pipe per year.
More cost-effective, expedient, less disruptive to adjacent services and quieter than open cut methods, the pipe bursting process is especially ideal for congested areas such as cities, municipalities and even manufacturing or industrial plants
A tried and true method for trenchless rehabilitation of existing pipelines, slip lining can be a fast, economical option to repair leaks or restore structural stability to an existing pipeline… especially when capacity is not an issue.
During this process first undertaken in the 1940s, a smaller-sized high-density polyethylene (HDPE) or other carrier pipe is butt fused together and inserted into an existing host pipeline. Using a cable and winch system, the new liner pipe can be pulled into place. Water-activated expanding grout and oakum are installed in the annular space to prevent leakage. When the new liner is in place, all service connections are reinstated with electro-fusion bonded watertight saddle connections.

Our remote-controlled cameras operate on a variety of sleds, tracks, and wheels to allow for quality video recording of various pipe types, materials, and sizes. KRG regularly TVs more than 4,000,000 linear feet of pipe per year with a dedicated TV fleet of more than 25 vehicles and supports video formatting for all of the most popular platforms including Cues, IST, RST, Aries, and Envirosight.
