Client's Challenge

The mining and metal producer needed to build a reinforced earth embankment incorporating two road tunnels, and a road along its crest, to improve access to one of its existing mines. The 13m high embankment, with 45° slopes, had to be easy to build by the clients team with limited geotechnical engineering experience.

Tensar Solution

Tensar’s design for the embankment incorporated layers of uniaxial geogrid to reinforce the embankment fill, and used geogrid gabions filled with rock fill to form the face of the steep slopes. The result was fast, simple and economical to build and provided long-term stability to the embankment.
