6/2012 – Securing an old retaining wall

When one retaining wall holds up the other: Securing an old retaining wall

Installer: Decorton Retaining System

When Lance Dickson of Lance Dickson Builders noticed that the old retaining wall surrounding his church in Loevenstein, Bellville was becoming unstable, he requested a quote from Decorton Retaining, a recommended retaining wall installer, for a Terraforce retaining wall:

“The old wall needed to be secured with another retaining wall. Terraforce was a logical choice due to the aesthetic and economical advantages this system offers.”

Fred Laker of ICOS Engineering designed the wall, which was installed with a foundation, geofabric reinforcement and sand filling behind to provide extra weight to support the existing retaining wall. A feature in the form of an indentation was added to the vertical entrance wall to accommodate the name board of the church.
