Capable of installing at a slope of 1:2 (50%), Grasscrete has been flow tested to rates in excess of 26 feet per second. This enables it to be used in exacting locations such as emergency spillways. The same testing process has also shown that when used in water flow Grasscrete is hydraulically efficient. Under heavy flow, long stemmed grass is flattened with the resulting thatch reducing the Mannings ‘n’ value for hydraulic roughness to as low as 0.03. Pre-cast concrete systems require infill panels to create directional changes. These spaces can cause turbulent flow that become a focal point for erosion, Grasscrete by contrast is a continuous slab with no such weakness.
Common Slope Protection Applications Include:
- Drainage Channels
- Emergency Spillways
- Access Roads and Ramps
- Detention/Retention Ponds
