Horizontal Directional Drilling

Horizontal Directional Drilling (HDD) is known as a steerable system for the installation of pipes, conduits and cables in a shallow arc using a surfaced launched drilling rig. Horizontal Directional Drilling is used in large-scale crossings such as rivers in which a fluid filled pilot hole is drilled without rotating the drill string, to be then enlarged by a wash over pipe and back reamer to the size required by the product. Home Directional Drilling includes trenchless Data Service, which is said to be an efficient, safe, cost effective method for highway bores.
