Terrafix® erosion control blocks
Terrafix is an interlocking environmentally acceptable element made of high strength concrete. It was specifically designed to provide a flexible lining where cost-effective protection against wind and water erosion is required. Terrafix can be laid in a variety of configurations to suit most site conditions.
The elements are made out of durable concrete and can therefore safely be used in most saline or polluted conditions. Units interlock laterally and offer a secure yet flexible lining. They are highly permeable but can be made impermeable by either placing an impervious membrane underneath the blocks or by grouting the structure with concrete or mastic. This makes it the ideal product to help combat the rapid degradation of our rivers and streams, caused by unbridled urbanisation and poor farming practices all over South Africa and the world.
