Open Cut Pipe Laying and Installation

VNSB has vast experience in the excavation and installation of various pipe diameters by open cut technique. Pipe and duct diameters can range from 50mm up to 1500mm down to depths in excess of 10 metres and lengths between manholes in excess of 150 meters. Open cut trench excavation is the traditional and most popular method for sewer lateral sewer construction, repair, or replacement. Open cut trench excavation consists of excavating a trench for the manual installation of each piece of pipe.  This method is usually the least expensive method if the pipe is located under non‐pavement areas such as a front or back yard.  The open cut trench method involves excavating down to and exposing the existing pipe so that it can be repaired or replaced and then backfilled. If the open cut trench excavation is located in a non‐pavement area the excavation can be backfilled with soil and surface vegetation.
