Trenchless Technology

How Trenchless Technology works

Clay Farm Rail Crossing Completed By Laser Guided Auger The Trenchless Technology technique used by FlowTEK involves the drilling of a pilot bore from the required start point along a predetermined route to the required completion point. 

Throughout this operation, adjustment can be made to the line and level of the bore.

The fluid assisted angular faced drill head carries a transmitting device in order that the position, depth, pitch and roll can be monitored on the surface.

When the pilot bore is complete, the drill head is removed and replaced with an appropriate back reamer. The cable or pipe is attached behind the reamer by means of a swivel and towing head. The cable or pipe is then installed as the drill string is retracted.

The fluids pumped through the rods to the head are vital to the process in that, in addition to lubrication and cooling, the polymers used help bind and stabilise the surrounding earth.

The ease with which the above operations can be carried out depends on a number of factors including the diameter of the pipe or cable to be installed, the length of the shot and the complexity of the route to be directionally drilled, with regard to any sensitively positioned underground services. Always of significance are the prevailing ground conditions and the knowledge and experience of the operatives with regard to the use of appropriate tooling and polymers as these factors are fundamental to a successful directional drilling operation.

Latest News

Flowtek have recently completed x3 drills installing 355mm Water Mains at Earnsdale Reservoir. 

The ground conditions consisted of very dense patches of rock, silt/ sands amongst clay. 

With such a variety of drilling conditions Flowtek utilised our Vermeer D40X55 and All Terrain Rock Drill along with our mud recycling unit, to succesfully complete all 3 drills within the timescale provided.

Flowtek have been involved with the A14 diversion of utilities, we have completed a mixture of 250mm and 355mm drills.

We have also completed 5 x 355mm water crossings in Scotland, across ditches and roads.
