Horizontal directional drilling

Horizontal directional drilling

Very versatile trenchless technology, especially suitable for service connections under buildings or pipelines under rivers and roads. In addition, it is the most appropriate method for installing pressurized conduits and pipes where there are no slope restrictions or tolerances. Its construction process consists of three phases:
01
Phase

Pilot drilling with small diameter drill bit from attack trench

02
Phase

Enlargement of guide drilling by means of a reaming head.

03
Phase

Installation of the product pipe by means of pull back.
