Anchors, Soil Nails, Rock Bolts

Subsol specialises in both active and passive anchors. A passive soil anchor is tensioned as the structure itself applies load to it. It does not usually have a free length of tendon (it is grouted over its whole length). An active soil anchor is pretensioned before it takes up the load, which is a means of limiting deformation. Unlike prestressed anchors, soil nailing and rock bolts cement the stabilised mass over their whole length. Soil nailing are mostly used in slope stabilisation.

Efficency driven by a professional team


Unless your retention system is designed to retain water, It is important to have proper drainage behind the wall in order to limit the pressure to the wall's design value. Our highly qualified engineers understand the need for tailored retention systems to offer the most efficient results at the highest possible quality.



Showing You The Way


Bored pile retaining walls are built by assembling a sequence of bored piles proceeded by excavating away the excess soil. Depending on the project, the bored pile retaining wall may include a series of earth anchors, reinforcing beams, soil improvement operations and a layer of shotcrete reinforcement. Subsol specialise in piling and quality assurance.



We have the technology


An anchored retaining wall can also include additional strength using cables or other stays anchored in the rock or soil behind it. Usually driven into the material with boring, anchors are then expanded at the end of the cable, either by mechanical means or often by injecting pressurized concrete, which expands to form a bulb in the soil. Technically complex, this method is very useful where high loads are expected, or where the wall itself has to be slender and would otherwise be too weak.
