Young Bros operate directional drilling rigs which are capable of drilling up to 200m long and laying pipes up to 500mm diameter. The rig uses hydraulic pressure and pressurised water to push a series of hollow steel rods through the ground. The direction of the drilling head is controlled by the plant operator. A pipe is then attached at the desired location and installed by the drilling rig. Young Bros utilise this system to install pipework under roads, rivers etc.

Young Bros also operate pipe bursting rigs that are capable of laying pipes up to 500mm diameter. The rig uses a series of steel rods to pull

the new pipe through the existing pipe. Young Bros utilise this system when renewing existing potable and foul water mains. Young Bros also utilise impact moles that are capable of laying pipes up to 150mm diameter.

The system operates by excavating a launch and reception pit in the locations desired. The impact mole is then lifted into the launch pit, and directed towards the reception pit. Compressed air then drives the mole until it reaches the reception pit. The new pipe will then be installed in the void created. Young Bros utilise this system to install service pipes and small mains over short distances i.e. under roads, hedges, streams etc.
