Horizontal Directional Drilling (HDD), is a leading trenchless technology due to the systems convenience and protection it gives to the communities and environments in which we operate. JTS have experience in achieving highly accurate graded drilling, with fine-tuned drill processes to overcome adverse ground conditions
Pipe bursting is ideal for pipe replacement as it is fast and non-invasive and uses the existing pipeline as a guide. Pipe Bursting cuts through the existing pipe while at the same time pulling a new one in its place.
Auger Boring provides a safe method of installing pipelines and cable ducts while supporting the ground during the bore. Auger Boring is a dry method of installation that causes very little or no disruption to surface, buildings, transport or the environment because the working area is confined to points of entry and exit.
Pipe Ramming is an un-guided trenchless method of installing steel pipes or casings, primarily (but not exclusively) to act as a carrier sleeve for water, gas, electric and telecoms etc.
Compared to traditional methods, Microtunnelling improves site safety, provides minimal disruption to the environment and communities and greatly reduces carbon footprint. We are able to provide Microtunnelling in diverse ground conditions, with an end results of a water tight finished pipeline.
The client was Welsh Water and as part of the AMP 6 works used Skanska to project manage the scheme with Joseph Gallagher Ltd appointed after a review of the technical issues regarding the works.
