Directional Drilling

Directional Drilling is a steerable boring system with depth and angle control. The Drilling method uses a traceable drill head on a predetermined route, navigating around underground obstacles.

A pilot bore is drilled between the 2 launch and receive excavations on the ground surface. The depth, angle and any obstruction during boring are controlled by a transmitter located in the drill head. The transmitter sends information to an above ground operator to make any necessary adjustments to the route.

Once the pilot bore is complete the operator removes the drill head and replaces it with an appropriate reamer. The reamer is pulled and rotated backwards to enlarge the drill route. This process is repeated incrementally until the required borehole diameter is reached.

The directional drill method causes minimum disruption to the environment and can be used to install pipe or ducts under any structure or around any obstacle. Directional drilling can be used to bore under roads, motorways, rivers, railways and new connections to developments

Pipe Bursting

Pipe bursting is a well established method for “Trench less” replacement of undersized gas, water, sewer and ducts

Pipes can be replaced without digging a trench, saving time, money, removal of waste and consequently minimising disruption to the ground surface. The existing pipe remains underground eliminating the need for its disposal.

An existing pipe is replaced size for size or can be up-sized with a new pipe in the exact location. This is possible because the pipe bursting head fractures the existing pipe as it is pulled through using pulling rods.

The movement of the bursting head forces the existing pipes broken fragments into the surrounding soil. Simultaneously a new pipe is pushed or pulled behind the bursting head.

We can burst through a range of materials such as, clay ware, pitch, fibre, concrete, asbestos cement, cast iron and u PVC.

Pipes and sizes of the client’s choice are installed using the pipe busting method.

Sliplining

Slip lining is a method of pipe renovation when the existing internal pipe diameter can be downsized to a smaller diameter pipe.

Slip lining is a cost effective and rapid form of rehabilitation of sections of pipe with very few service connections and sharp bends in the existing pipe.

Open cut trench

This method involves the digging of a large trench, into which the new pipe is laid and the soil backfilled when in the verge. When the trench is dug in the road the excavation is backfilled with pipe-bedding, stone and Tarmac is compacted in layers.
