This is the first and the most important step of the entire HDD process. Before drilling the actual pipeline, a pilot bore is drilled from the entry pit to the exit pit. A surveying system is installed through the entire route to analyse the progress of drill rods and guide them to the right direction. Mud Pumps are used to provide bentonite suspension mud for drilling. The bentonite is extracted back from the excavated material for reuse at the recycling unit. Bluegrass Technologies offers drilling equipment, surveying system, experienced manpower, and recycling units for pilot bore hole drilling requirements.
