As most municipalities have grown over the years, tunneling new utilities or tunneling to upgrading utilities have become common when you need to bury your utilities deeper or you require crossing major roadway or waterway. At Rinker Materials, we manufacture micro-tunneling and jacking pipe.
Micro-tunneling is a trenchless construction method for installing pipelines beneath the surface in a wide range of soil conditions without expensive dewatering systems. It uses a slurry to carry the spoils away from the tunnel heading to the main work shaft.
Pipe jacking, is a technique for larger diameter pipe 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 is taking place within the shield. The method provides a flexible, structural, watertight, finished pipeline as the tunnel is excavated.
