Grasspave2 grass paver is a structure which provides incredible load bearing strength while protecting vegetation root systems from deadly compaction. High void spaces within the entire cross-section enable excellent root development, and storage capacity for rainfall from storm events. For example, a 13 inch cross-section (one inch Grasspave2 with sand and a 12 inch base course) can store 2.6 inches of water – 13 inches x approx. 20% void space). Stormwater is slowed in movement through and across Grasspave2 surfaces, which deposits suspended sediment and increases time to discharge. Suspended pollutants and moderate amounts of engine oils are consumed by active soil bacteria, which are aided by the system’s excellent oxygen exchange capacity.
