Project: Retaining wall at Monte Casino in Four-Ways near Johannesburg.
Client: Tsogo Sun Casinos
Designed by: A.F.Wild of B.K.S. (Pty) Ltd.
Installed by: Kalode Construction (Pty) Ltd.

This Terraforce wall with a face area of 2700 m² and average height of 9m was completed within 4 months. The design is based on Terraforce L13 blocks placed on a 25m.p.a. concrete foundation and built to full height in chainages of about 60m.

The lowest - 12 - rows of blocks are filled with a cement stabilized load bearing mix while the fabric reinforced backfill is made up of 5% cement stabilized soil (mixed with a T.L.B, placed with a Telescopic Loader) and compacted to 93% mod AASHTO. Light and heavy grades of woven geofabric were specified depending on their position within the wall. Insitu concrete shear keys were installed every row and every other block, including rows with fabric layers. All geotextiles were pre -tensioned in warp direction before placement of backfill. An extensive drainage system is provided - click here to view a graphic illustration.
