System development
Early systems were heavy relative to bore size and were prone to deviation or loss of the unit underground.

Short-distance applications
As accuracy improved, the technique became widely used in trenchless excavation for a variety of installation problems.
Origins of impact boring
Impact moles first appeared in Poland and Russia during the 1960s.
Early systems were heavy relative to the bore size and frequently suffered problems such as significant deviation from the intended path or loss of the unit underground.
Development and accuracy
Since then, impact moles have been developed to achieve much greater accuracy.
Today they are probably among the most widely used trenchless excavation tools worldwide.
Main applications
The technique provides a solution to a broad range of installation problems.
It is particularly well suited to short-distance applications.
