Case studies - Stormwater control, weirs & spillways (page 1)

In nature, a near balanced situation exists between precipitation, runoff and infiltration. An ever-increasing rate of urbanization is upsetting this equilibrium and causing severe soil erosion problems. Over the years, Terraforce and Terrafix blocks have proven their value in finding environmentally sound solutions, so much so that Mr Holger Rust was invited to the World Summit of Sustainable Development in Johannesburg, August 2002, to give a presentation on Terraforce's involvement in ongoing erosion control.



Turbulence and rushing water can wash out other erosion control systems. Due to Terraforce blocks' ability to withstand turbulence and water velocities of up to 6m/sec, the Johannesburg City Council often relies on these blocks.

Stormwater channels, cascades, spillways and weirs can be constructed with Terraforce/Terrafix blocks. Professional planning is critical in these instances. [back to index]
