Pipe Ramming


We can use our Grundoram Koloss tool to ram steel casings up to 1200mm diameter on grade and alignment under linear obstructions such as railways or highways. This is a cost effective method of creating new service crossings of existing infrastructure.

Pipe ramming removes the requirement to excavate through an existing feature such as a highway or railway. It can eliminate the cost of extensive temporary works, tight time constraints and significant safety hazards.
