For over 20 years, EQUANS has been a recognised expert in horizontal directional drilling (HDD) and is one of the main Belgian experts today for complex and special drilling. Horizontal directional drilling enables us to create underground infrastructure over long lengths following the ‘no-dig’ principle (without a trench).
This technique is precise, effective and presents three major advantages: limitation of nuisance in the surrounding area; rapid execution and minimal excavation.
We work on lengths that can reach 1,200 metres and diameters of 1.2 meters, both for polyethylene and stainless steel pipes. Drilling with an optical gyroscope enables us to keep to the drilling trajectory with remarkable precision.
To assist the department, we have a team of experts and draughtspeople who, thanks to specialist software, are able to create the preliminary studies, the ‘mud pressures’ and ‘as-builts’ of this drilling.
