Grasscrete is a cast-in-place, rebar reinforced concrete slab containing a series of voids created by a patented forming process. These voids are subsequently filled with a variety of materials from stone through sand and soil planted with a wide variety of vegetation. The Grasscrete system selected can be purely functional or can be a concealed pavement that is both functional and pleasing in appearance. Grasscrete offers the end-user the ability to provide year-round access for a variety of applications requiring structural paving without compromising the aesthetics of their exterior landscaping or having to utilize traditional hard pavements, minimizing the need to control storm water runoff.

Stone Filled Grasscrete Systems: Ideal for sustained traffic areas, the Grasscrete system can be filled with stone for maximum percolation rates and water retention. Stone filled systems are capable of draining at rates of up to 480 inches per hour with 100% retention of water possible with correct design. the stone filled application is ideal if seeking a low maintenance design.

Slope Protection Grasscrete Systems: 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.

Concealed Grasscrete Systems: Ideal for low traffic volume areas, the Grasscrete system can be completely concealed with vegetation so it is functional, environmentally friendly and pleasing in appearance. Grasscrete offers the end-user the ability to provide year-round access for a variety of applications requiring structural paving surfaces without compromising the aesthetics of their exterior landscaping and having to utilize traditional hard pavements, minimizing the need to control stormwater runoff.

Partially Concealed Grasscrete Systems:  The ‘feel good’ factor of greenspace cannot be overlooked as street scenes are softened without losing essential structural performance. Greenspace within urban areas is invaluable in balancing CO2 levels created by vehicular traffic. Located at the actual point of emission, the natural digestion by a grassed parking area can help to avoid atmospheric CO2 build up and reduce the “urban green island effect”.
