CME's service saved from having to excavate and tear up recently re-surfaced blacktop at our office building. All work was done in a two-foot square area just outside of the basement foundation in less than six hours. A 102-foot main soil drain was re-lined with a brand new joint-free pipe just like regular PVC. Guaranteed for 10 years, but will most likely last as long as brand new PVC piping laid instead. Top notch repair work done by a three-man crew, younger guys who took pride in their workmanship. Saved probably more than half-price if done by regular excavation procedures, and done without any degradation of the existing lawn and pavement from the building to the street. Since they do a visual inspection for free (and provide you with a copy of the video afterward), I would recommend that this inspection be done for any building, residential or commercial, prior to any real property purchase. TIm, Nick and Brent showed up an hour early on the weekend and did a great job!
