Terracrete Hardlawn Block

EROSION CONTROL AND PERMEABLE PAVING

Terracrete is an interlocking, environmentally friendly unit, 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. It can also be specified as a hard lawn - drive over, for light or heavy vehicles, when provided with a well designed subbase. Click here for example application.

Terracrete, manufactured locally and internationally by Terraforce licensees, is a versatile eco-surface hard lawn paving block that was introduced to the market in 2002. The units can be laid in different patterns and may be used with or without ground anchors for the lining of riverbanks and other areas subjects to soil erosion. The paving of grassed roads and parking areas, as well as the stabilising of steep embankments such as bridge abutments can be undertaken with these versatile blocks.

Terraforce has also recently combined forces with a permeable paving expert and consultant who can provide designs and engineering support with regards to these type of surfaces. please click here to find out more.

Block	Terracrete
Blocks/ m² (Measured on face)	6-9

These durable concrete units may be used in most saline or polluted conditions, interlock laterally and offer a secure, yet flexible lining. This product has been specified in applications designed to charge our dwindling ground water reservoir and to provide a perfect regime for establishing vegetation.

Terraforce erosion control products have successfully been installed on river banks subject to water velocities of up to 6m/sec. and on estuaries / beaches with moderate wave action.

According to Holger Rust , owner of Terraforce, landscape contractors have recognised the many benefits of installing permeable interlocking concrete pavers.

"From an aesthetic point of view, they are very versatile, adds Rust. "The homeowner or the developer want the house to look good." A grass driveway, a rustic gravel driveway, or an attractive pattern of pavers can add the finishing touch to a custom home looking to stand out. Permeable grass pavers can add a park-like or pastoral feel to many areas normally needing hard paving.

Designed with sufficient strength and adequate stiffness Terracrete pavers are capable of accommodating (with suitable sub-base construction and in combination with ground anchors) vehicular traffic and the substantial uplifting forces caused by high water velocities.
