Metro Earthworks offers our Trenchless Sewer Line Repair Technology to Minneapolis, St. Paul and its Surrounding Suburbs. Our cured-in-place pipe (CIPP) technology is one of several trenchless rehabilitation methods we use to repair existing sewer pipelines in the Twin Cities. This technology is a jointless, seamless, pipe-within-a-pipe. As one of the most widely used rehabilitation methods CIPP has application in water, sewer, gas, and chemical pipelines. As a trenchless technology, CIPP does not require excavation to rehabilitate a pipeline that is either leaking or structurally unsound.
