Microtunneling Projects

Microtunneling is a method of steerable remote control pipe jacking, and is considered the most precise pipe jacking method. It can cover the longest distances, and can handle variable ground conditions. Generally, microtunneling doesn't cause much subsidence compared to other pipe jacking methods.

Pipe Ramming Projects

Pipe ramming is a non-steerable method of forming a bore by driving a steel casing, usually open-ended, horizontally through the ground with a percussive hammer. The soil may be removed from an open-ended casing by augering, jetting or compressed air. In appropriate ground conditions, a closed casing may be used. Since the material is not excavated until after the pipe has been driven into place, there is little or no settlement of the surface roadway or railbed.

Auger Boring Projects

Auger boring is a pipe jacking method of forming a bore by means of a rotating cutting head. The equipment may have limited steering capability, and auger boring is limited in the distance it can cover, but it is the most cost-effective method of pipe jacking.

Horizontal Directional Drilling Projects

Horizontal Directional Drilling (HDD) is a fast method of trenchless construction that uses guided drilling to permanently place pipe beneath both natural and man made barriers such as rivers, shores, roads and buildings.
