Horizontally directional drilling (HDD) is a trenchless method of utility construction.

Suitable for work where it is not possible to use the open trench method (for example, under trees, railways, roads, water bodies, buildings or existing communications). In addition, this method reduces the costs of constructing communications. The HDD process uses a drilling mixture that ensures the stability of the borehole and helps remove excess soil. The mixture is environmentally friendly and usually consists of approximately 95% water and 5% bentonite clay.

HDD involves two main stages:

  • pilot hole;

  • pipe insertion.

Pilot bore
Using a location unit, small diameter holes are created along the selected trajectory.

Pipe insertion
After the pilot hole is created, the location unit is replaced with the required channel expander, to which the pipe is attached and pulled into the prepared channel.

SIA “RECK” also offers horizontal directional drilling as a separate service to other builders, providing maintenance, as well as specially trained and qualified employees.

Method used

SIA “RECK” uses Vermeer HDD equipment and DigiTrak location units for construction of engineering communication networks. This technology is suitable for the installation of underground communications, including the construction of water pipes, gas pipes and telecommunications networks.

We are able to build communications up to 300 m long, 15 m deep and with a channel extension up to 650 mm in diameter.
