TERRAFIX is an interlocking concrete block system designed for erosion control applications such as embankments, storm water channels, and riverbanks. The blocks are durable, permeable, and flexible and can interlock in various configurations to suit site conditions. A study found TERRAFIX has positive characteristics for hydraulic applications such as erosion control and water flow management. The system helps prevent soil erosion while preserving groundwater and biodiversity.

Flexible and permeable erosion control block:
TERRAFIX is an interlocking environmentally acceptable element made of high
strength concrete. It is designed to provide a flexible lining where cost-effective
protection against wind/water erosion is required. Available in 3 different
thicknesses. Can be laid in a variety of configurations to suit 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.
Terrafix can help prevent our soil being eroded away, while still
being permeable enough to help preserve our precious ground water reserves
and biodiversity.

A feasibility study into the hydraulic applications of the TERRAFIX system
by the division of Earth, Marine and Atmospheric Science and Technology
of the CSIR has revealed very positive characteristics. A copy of this report
is available on request.
