The GEOBLOCK Porous pavement system comprises the following major components: • GEOBLOCK unit • Engineered Base support (if required) • Selected infill (topsoil / vegetation, other appropriate infill) Depending on sub-base and loading, the GEOBLOCK unit may be placed directly on the subgrade without additional base materials. For heavier loads or with soft subbase, both the GEOBLOCK unit and the engineered base work together to support the imposed loading. With vegetated systems, the Geoblock units protect the topsoil from compaction and the vegetative root zone from damage. The Geoblock units also offer permeability and stability of infill in non-turf applications
REDUCES STORMWATER RUN-OFF AND ENHANCES GROUNDWATER RECHARGE Geoblock porous pavement surface geometry reduces run-off, increases infiltration, resists erosion, and enhances groundwater recharge. Geoblock porous pavement presents over 80% open area to the surface. This design allows water to percolate into the ground through drain holes in the bottom of the blocks. PROTECTS THE CROWN OF THE GRASS AND PREVENTS SOIL COMPACTION Geoblock porous pavement directly supports the weight of pedestrian and vehicular traffic on its cell walls, protecting the crown of the grass and prevents over-compaction and deaeration of the topsoil. Geoblock porous pavement provides further support for healthy grass growth by permitting the use of a soil-and-sand or soil-and-gravel mixture for the subbase. The Geoblock system provides total design flexibility, since it allows a load-bearing pavement to be located in areas where drainage and the natural beauty of grass are desired.
GEOBLOCK 5150 is suitable for heavier vehicles (occasional use) - fire truck and delivery truck applications. For lighter vehicles – cars, pickups, etc., use GEOBLOCK 2.
