PRODUCT DESCRIPTION

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.
