Moling
Pipeline Services will install your new supply pipe using the trenchless technology known as impact moling, in which percussion or hammering action of a pneumatic piercing tool is used to create a bore by compacting and displacing the soil rather than removing it. When properly employed, impact moling is the simplest and least expensive trenchless technology installation method.
The general advantages of impact moling are:
- Low operational and reinstatement costs
- Less expensive than traditional trenching methods
- Suitable for all soil conditions except rock
- Minimal or no excavation beyond the necessary connection pits or termination points for the installed water main
- Minimal disruption to the customer and customer’s property in comparison with traditional trenching techniques
- Environmentally and socially beneficial
The installation site to be pierced must be sufficiently displaceable. A pit is required for the start and is usually located at the boundary close to the external stop tap. A second pit is required to receive the mole and is located at the entry point into the property. Depending on the distance to be moled will depend on whether or not a third hole will be required. Installation times vary, however, we endeavour to install the new supply within 1 day and dependent on soil conditions we expect to achieve a propulsion speed of 15 metres an hour. |
