An Overview of HDD

HDD consists of a three-step process. We create the pilot hole, enlarge it and feed the pipe through. HDD works under waterways, interstates, roads, and other infrastructure. With no trenches, surface features remain intact. In preparation for the installation, we need to determine the bore path of the pipe along a shallow, underground arc. We also estimate the load that should be applied to the pipe during pullback and choose an appropriate pipe for the project.

Upon boring the pilot hole and the emergence of the bit in the exit pit, we remove the drill bit then place the reamer on the end of the pipe string and pull back to enlarge the borehole. This hole should be about 50% larger than the pipe. We then fuse lengths of polyethylene pipe together. The pipe is heated and the molecules undergo a transformation into a crystalline state, enabling a seamless joining of the pipe. The end result is a fusion joint that is as strong or stronger than the pipe itself.
