Soil Nails are used to provide cost-effective short and long-term stabilisation for roadway cut excavations, tidal areas, landfill caps, dams, basements, slope stabilisation or retaining wall support, or for emergency works following a riverbank collapse or landslide.
Soil nails provide long term stability to existing concrete structures without demolition and rebuilding.
In the following article, we answer the three main queries asked by building contractors looking to use Soil Nails as part of their project:
Yes. The greatest advantage of soil nail walls is their cost-effectiveness over other alternatives. Soil nails are rapidly installed and require little space to manoeuvre, therefore not only does a team need less time on-site to install – depending on the works – other disciplines can continue to work and keep the overall project moving.
When conventional soil nailing construction procedures are used, soil nail walls are much more economical than concrete gravity walls as well as more cost-effective than ground anchor walls.
Ground anchor and soil nail retaining systems are both designed to stabilise and support natural and engineered structures and to restrain their movement using tension-resisting elements however there are some key differences.
Soil Nails are typically grouted bars that may or may not have double corrosion protection. Often, the tendon is designed to be either tabular (tubular) or solid that transfers tension forces into the ground. Otherwise known as pre-tensioned tendons. Whereas ground anchors are post-tensioned tendons that transfer tension from the unstable exterior to the underlying interior rock mass; hence, providing substantial reinforcement.
