Soil nails are highly versatile methods for slope stabilisation and earth retaining structures, which can be used in a wide range of ground conditions with low environmental impact.
Soil nails are more suited to cohesive soils and are solid steel bars drilled into slopes with grout flush or inserted into pre-drilled holes and grouted into place. Hollow bar self-drilling soil nails are screwed into the ground with grout pumped down their centre to fix them into place. A steel plate is attached to the end of the nail and mesh attached to hold the slope face.
Tie rods are used to stabilise structures and are installed horizontally or at an angle through masonry, concrete, fill and natural ground.
Van Elle offers a complete range of hollow bar and self drilling soil nails and strand, solid bar and double corrosion protection ground anchors, installed using tracked or wheeled Soilmec and Casagrande drilling rigs.
