Soil Nailing

Soil Nails provide a wealth of advantages over other slope stabilisation methods. Half the cost and twice as quick to install as concrete piled retaining walls, they can be used to form steeper slopes than an engineered embankment.

Tendons are inserted into a nominally 115mm diameter hole which is then tremie grouted. As the nails are designed to act as a composite system they are connected by a geogrid which covers the entire slope and is fixed using concrete plates with the tendon secured using a wedge grip mechanism.
