EXCAVATION SERVICES ON OAHU
OPEN CUT TRENCH EXCAVATION
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 “stick” or 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 restored by seed or sod. When the open cut trench excavation is located under pavement the existing pavement must be saw cut and removed, the excavation filled with granular backfill (compacted stone or sand to prevent settlement), and the pavement must be replaced and the end of the pipe repair or replacement. If a small section of pipe is being replaced a Fernco type coupling is used to provide a water‐tight connection to the existing pipe. A Fernco type coupling consists of a rubber sleeve that the pipe fits inside of and is fastened to the pipes using stainless steel bands that wrap around the outside of the sleeve.
