For underground infrastructure building in typical urban areas, poor ground conditions and for all underground construction in weak and disturbed soils modern tunneling engineers have developed a face stabilization and protection system called “Tube Umbrella” or “Forepoling”. The method is based on the use of drilled piped (tubes) in the advance of the tunnel face. Antraquip is leading the way in offering complete systems which include all components needed for forepoling and roof piping applications wherever dripping is required.
