Trenchless Repair

DeLong Services was one of the leading companies to bring trenchless pipe repair to the Dallas / Ft. Worth Metroplex. We use patented Nu Flow sewer liners to repair deteriorating lines, separations, and cracks.

Founded in 1998, Nu Flow is an industry leader in trenchless technology and secured the first patent for “sleeve within a sleeve” pipe repair in 2005. Watch our video to see exactly how we repair sewer leaks without digging.
