Slope Protection

Slope weather protection is important to control soil erosion down slope as a result of direct rainfall and surface runoff. Protection can be a permanent slope covering or a temporary measure until the excavation has been backfilled. Uncovered slopes undergo surface ravelling and gulleying, leading to instabilities and safety concerns. Soil erosion is normally prevented by applying a thin concrete skin.

However, this is difficult to apply uniformly and often breaks apart. Plastic sheeting covers are disturbed by strong winds, water flows or site damage and meshes do not provide the same level of direct weather protection.

Concrete Cloth (CC) provides a quick means to directly apply a thin, uniform, protective concrete covering to the slope surface and can be applied in all weather conditions. CC is fixed by short nails and provides a strong, waterproof, surface stabilising covering enhanced by internal reinforcing fibres.

CC can be used in conjunction with full length soil nails to increase the stability of slope surfaces by providing similar slope protection measures. CC can also be used to cover landslide scars or cut slopes. Holes can be cut to allow vegetation growth
