	A steer-able system for the installation of pipes, conduits and cables in a shallow arc or on grade using a surface or pit launched drilling rig. Drill fluids are used for cooling and lubrication. Tracking of the drill head can be from the surface or from down hole tooling. Our directional drilling equipment is capable of installing pipe up to 500mm diameter and 250m in length.

	A simple method for installing small diameter services or short lengths. An air powered impact tool forces its way through the ground towing the service pipe behind it. We operate 4 thrusting tools which cater for pipe sizes up to 110mm diameter. Length is dependant on ground conditions, 15 to 20 metres is achievable. Thrusting is a suitable option for installing water lines, sewer services (depending on grade required), gas line replacements and communication ducts.

	In one process we Auger bore a hole, remove the spoil and jack in a pipe. This method is suitable for short lengths and is very suitable for hard ground or where special pipes need to be installed. We can install diameters up to 1.2m with this method in certain ground conditions.

	A steel casing is driven through the ground, open-ended, once it reaches the target, the soil inside the pipe is cleaned out. We have a Gigant Grundoram that is capable of driving diameters up to 700mm in suitable ground conditions. The Goliath Grundoram is capable of diameters up to 1.0m. Range is dependant on ground conditions and pipe diameter but lengths of 40 to 50 metres are possible.

	Pipe bursting is an on line pipe replacement technology. Pipe busting involves replacement of a host pipe by fragmenting the existing pipe and installing a new pipe of equal or larger diameter in its place. Pipe bursting is a good alternative to open cut construction and is suitable for replacing water lines, sewer mains, sewer service pipes, gas lines and communication ducts. The pipe can either be replaced size for size or up sized to an extent dependant on the ground conditions. We are able to burst pipe up to 450mm diameter depending on the conditions We also use a Lateral burster for pipes up to 150mm in diameter and 25m in length.

	Can't find what you were after? Other services may be available depending on the project. Contact us to discuss what other solutions we have for your project.

	Because this is a relatively new technology, which is rapidly developing, we have developed a presentation that introduces the range of operations covered by the title of Trenchless Technology. The presentation is made up by our General Manager and includes as much up to date information from overseas conferences etc as we can. More than 20 of these presentations have been made for group sizes ranging from five to 60 people. The presentation takes approximately 2 hours and is free providing air travel or overnight accommodation is not required.
