In the construction industry, Impact Moling is a trenchless method used to lay pipes. During the Moling process, a compressed air-driven machine, known as a Mole, forces its way through the ground along the desired path of the pipe. Moling avoids the need to dig a trench and can be used to lay water pipes and cabling as required by utility services without the need for trenches being opened across roads.

Trenchless technology, as the name implies, stands for subsurface construction works where less trenches or no continuous trenches are required to be dug. It is a rapidly growing sector of the construction and civil engineering industry. It can be defined as "A family of methods, materials, and equipment capable of being used for the installation of new or replacement or rehabilitation of existing underground infrastructure with minimal disruption to surface traffic, business, and other activities.

In this instance a hole was dug in the verge of the road, to accommodate the cradle of the Mole. Using sighting equipment, the Mole can be accurately positioned and aimed to emerge at a desired location and depth.
