Horizontal directional drilling or HDD is a steerable trenchless method of installing underground pipes, conduits and cables in a shallow arc along a prescribed bore path by using a surface launched drilling rig, with minimal impact on the surrounding area. Directional drilling is used when trenching or excavating is not practical or cost effective. It is used for installing pipes from 40mmØ to 800mmØ. Ideal for bores from 25 metres up to 1500 metres in a wide range of ground conditions. Can also be curved to bypass obstacles. Pipes can be made of materials such as PVC, polyethylene, ductile iron, and steel.

MJ Rees has worked with contractions in this sector to provide positional checks and location data for their pipework. We are able to provide this using a unique pipe location system, REDUCT.

The REDUCT Technology is a patented gyroscope-based inertial measurement system designed for autonomous recording of positional data of pipelines.

Reduct Pipeline Mapping Systems produces accurate coordinates of the pipe, which can then be presented in 3D in CAD to the client.

Our team of dedicated surveyors have been actively involved with numerous Reduct projects across the UK. For further information please see our REDUCT pages under ‘Our Services’ and ‘Projects’.
