Methodology for Utility Installations
The method of installation for underground utility services is dependent on the project being undertaken. Before any work commences, drawings of all existing services in the area need to be examined. A CAT survey would then be completed to ensure that it is safe to instigate any construction work.
Impact Moling
We would scan the area and determine the safest place to dig the launch and receiving pit. Next, we would set the mole in operation in a pre-determined line from pit to pit.
Trenchless Technology Techniques
This is utilised whenever practical by using directional drilling rigs or impact moling, avoiding having to dig a long trench - this is a lot less disruptive to the surrounding roadways and businesses. We also use trenchless technology to lay piping and cables.
Conventional Open Cut Trenching
This is completed through the use of a high-speed chain type trenching machine, a conventional excavator or by hand dig.
In certain circumstances, existing water pipes may be slip lined, by inserting a new smaller diameter pipe inside the existing pipe - this ensures the least amount of reinstatement necessary.
