Hollow Bar Anchoring

The Hollow Bar Anchor is a fully threaded self-drilling anchorage system which can be simultaneously drilled and grouted into loose or collapsing soils andbrittle rock without the need for a casing.Grout is injected at all points of the borehole as drilling is advanced, permeating the local strata for increased bond performance and producing bulbing between the strata and the hollow bar in the softer sections of the soil.
