Shtang is the leading company in Israel executing complex pipe jacking of water and sewage pipeline projects, and has successfully executed many such projects over the years; including under the sea. We are also one of the rare companies that has executed projects using unique methods such as restoring sewage lines using ferro-cement technology.
Pipe jacking (generally referred to in the smaller diameters as micro-tunneling) is a technique for installing underground pipelines, ducts and culverts. Powerful hydraulic jacks are used to push specially designed pipes through the ground, behind a shield at the same time as excavation takes place within the shield. The method provides a flexible, structural, watertight, finished pipeline as the tunnel is excavated. This method allows for installing underground pipelines with minimum surface disruption. Primarily used for new sewer construction, it is also used for sewer replacement and relining, gas and water mains, oil pipelines, electricity and telecommunication installations, culverts and subways.
