Directional boring:
commonly called horizontal directional drilling or HDD, is a steerable trenchless method of installing underground pipes, conduits and cables in a shallow arc along a prescribed bore
path by using a surface-launched drilling rig, with minimal impact on the surrounding area. Directional boring is used when trenching or excavating is not practical. It is suitable for a variety of
soil conditions and jobs including road, landscape and river crossings. Pipes can be made of materials such as PVC, Polyethylene, Polypropylene, Ductile Iron, and Steel if the pipes can be pulled through the drilled hole. The process starts with receiving hole and entrance pits. These pits will allow the drilling fluid to be collected and reclaimed to reduce costs and prevent waste. The first stage drills a pilot hole on the designed path, and the second stage (reaming) enlarges the hole by passing a larger cutting tool known as the back reamer. The reamer’s diameter depends on the size of the pipe to be pulled back through the bore hole. The driller increases the diameter according to the outer diameter or the conduit and to achieve optimal production. The third stage places the product or casing pipe in the enlarged hole by way of the drill stem; it is pulled behind the reamer to allow centering of the pipe in the newly reamed path. Horizontal directional drilling is done with the help of a viscous fluid known as drilling fluid. It is a mixture of water and, usually, bentonite or polymer continuously pumped to the cutting head or drill bit to facilitate the removal of cuttings, stabilize the bore hole, cool the cutting head, and lubricate the passage of the product pipe. Our services include a variety of different utilities. We can pull many different sizes of pipe, anywhere up to 15 inch diameter. Water – Mainline and Services (We can also drill into basements)
Sewer – Forced, or On Grade. Hydro – Single or Multiple Ducts
Irrigation
Geothermal – Geothermal horizontal loops can be drilled, Less restoration than open cutting. Communication lines – Single or multiple ducts of different sizes.
