Terracrete Erosion Control Blocks

Terracrete Erosion Control Block ®

Terracrete, manufactured locally and internationally by Terraforce licensees, is a versatile eco-surface hard lawn paving block. 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 subject 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.

Landscape contractors have recognised the many benefits of installing permeable interlocking concrete pavers. From an aesthetic point of view, they are very versatile. 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.
