Moling

In the construction industry, moling is a trenchless method used to lay pipes.

The standard approach to moling is to dig a hole about 1 m square and 2 m deep.

The mole is then entered into the earth on the horizontal face at the bottom of this hole.

A destination hole of similar proportions is also dug, and this is where the mole emerges.

Once the mole has passed through the earth the pipe can be pulled through the long horizontal hole.
