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.
99 HDD crossings included major roads, rivers, canals, ditches, dykes and SSSI as well as drilling in different ground conditions.
The Murphy and Joseph Gallagher Teams used Horizontal Directional Drilling (HDD) and Microtunnelling to overcome several challenges on the project to install the new pipeline
We have been contracted by UKPN and Clancy Dowcra to design and construct two HDD crossings from Willesden Grid main substation to the new substation on Atlas Road.
We were contracted to undertake six HDD crossings at three locations drilling under Network Rail assets for UKPN and Clancy Dowcra. Each location required two separate bores reamed up to 22inch, with each bore housing nine electric ducts.
Joseph Gallagher were contracted by Fastflow to undertake diversion works on a high-pressure gas main for National Grid.
The A13 Road Widening Project is being delivered by Kier on behalf of Thurrock Council. The works include adding an additional lane in both directions between Orsett and Stanford-le-Hope and replacing four bridges.
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.
This pumping station and associated works was undertaken as a turnkey package for civil and MEICA works.
JTS were initially contacted to provide a quote for “directional Drill” river crossing to install a 450mm PE Rising main.
This project was designed to remove area flooding, by transferring flows to the Clapham trunk sewer located in Clapham High Street, a main arterial route to the city centre.
Johnston Trenchless Solutions were invited to provide solutions for the rehabilitation of an existing Severn Trent Water Combined Sewer.
JTS were initially invited by the Coal Authority to provide a report to determine the feasibility of installing a mine-water discharge pipe some 500m into the North Sea near Sunderland.
The initial sub-contract award was for the construction of two segmental shafts, required for the installation of a 2100mm diameter pipejack under the M60 motorway.
Installation of a 150m x 500mm OD SDR11 PE sleeve under the Grand Union Canal in Warwick. An environmentally sensitive crossing with challenging ground conditions comprising of gravels over very stiff clay and mudstone.
JTS were approached at conceptual stage of the project to provide solutions to a number of watermain diversions required ahead of a scheme to widen the A1M in North Yorkshire.
