Self Driven Anchor

Self-Driven Anchors (SDA) is a fully threaded steel bar which can be drilled and grouted into loose or collapsing soils without a casing. The bar features a hollow center for simultaneous drilling and grouting and a rope thread for connection to standard drill tooling. SDA forms a standard rope thread profile (R25 - R51, T76 has a trapezoidal thread). SDA can be installed into a variety of different soils and ground conditions ranging from sand and gravel to inconsistent fill, boulders, rubble and weathered rock, as well as through footings and base slabs.
