Horizontal Directional Drilling (HDD)
“Hard terrains is our specialty”
Horizontal Directional Drilling (HDD) is a trenchless method of installing pipelines and conduits in the areas where traditional open cut excavations are not feasible and/or not desired for environmental and/or constructibility reasons. It is commonly used for the installation of pipelines beneath rivers, highways, railroads and other environmentally sensitive areas, or areas where the topography or site conditions along a proposed alignment conflicts with conventional cut and cover installation practices.
During the HDD process, a pilot hole is first drilled along a predetermined path. The pilot hole is then enlarged in single or multiple steps (reaming passes) to accommodate the pullback of the carrier pipe into the enlarged hole. GEP is currently operating HDD rigs capable of completing both large and small projects.
Since established, GEP has drilled over 10,000 meters of length, and up to 22 meters of depth. Some of GEP’s fleet consists of multiple Vermeer D330x500 rigs, Ditch Witch 4020 rigs, Ditch Witch JT 100, Vermeer D100x120, Vermeer D36x50, Ditch Witch 3020, etc. The range of capacity in these rigs combined with a series of specialized drill bits and the air hammers provide the opportunity to match the equipment to any field conditions in the Middle East, including rock and cobblestone conditions.
