Directional Boring Underground Construction (36)

Underground lines and conduit can be installed using HDD (Horizontal Directional Drilling). This process uses drilling technology to bore a small hole from one location to the next. Once the drill rod comes to the end of the bore the new pipe is attached and pulled back eliminating open excavation. This technology can be used to install lines and conduit under roads, railroads, ponds, lakes, streams, industrial buildings, etc. without the impact of open excavation.

Pipe Reaming Services

Express Plumbing utilizes a trenchless method for the removal of existing VCP & PVC pipe and simultaneous replacement with an HDPE or PVC pipe of equal or larger diameter.

Removal of the in-place pipe is accomplished by “back reaming” using a directional drilling machine with a cutter head that reduces the existing pipe to small pieces which are carried along with other excess particles by the drilling fluid to an extraction point.

This method is used in place of pipe-bursting. It does not compress the solid and can be used for greater up-sizing.

Pipe Ramming Services

A method of installing steel pipes and casings over distances usually up to 150 ft up long and up to 55-inches in diameter, although the method can be used for much longer and larger installations. The method is the most useful for shallow installations under railways and roads, where other trenchless methods could cause surface settlement or heave. The majority of installations are horizontal, although the method can be applied for vertical installations as well.
