Horizontal Directional Drilling (HDD) is an above ground surface to surface trenchless method used to install pipelines and conduits in areas where conventional excavation methods are not feasible and/or desirable for environmental and/or constructability reasons. Bortech Company, Inc., has employed the HDD method under rivers, creeks and streams, highways, railroads, airports, ocean beaches and environmentally sensitive and delineated lands.
The HDD process is performed by first drilling a smaller pilot hole that is directed by the drill operator who follows a pre-designed and approved bore path. The second step is to enlarge the completed pilot hole in a single or multiple successive passes to accommodate the product pipe or carrier pipe. The third step is to proof the enlarged hole to validate the integrity of the bore hole. The final step is the pulling in or installation of the desired product pipe or conduit.
Bortech provides HDD services that range from;
Large or Maxi Directional Drills with capabilities of 5,000 feet in soft soils to hard rock formations.
Small Directional Drills under 100,000 lbs of pulling capacity for intermediate capabilities in soft soils to hard rock formations.
