Gravel stabilization grids enable the construction of permeable parking lots, driveways, walkways and trails etc. The cells hold in place the otherwise loose and free moving gravel resulting in the comfort and stability of a paved surface. The grids are designed to withstand extreme downward force along with resisting lateral forces which can be caused by turning tires or changes in direction.
The merit of constructing areas such as parking lots and pathways etc. as being permeable is significant on many facets.
Urban development typically leads to a disproportionately large percentage of land in a given area which becomes impervious. This leads to imbalances in storm water management on many fronts, such as erosion from run-offs and flooding.
Storm water streams along concrete, asphalt or other impervious surfaces, collecting petroleum based pollutants such as diesel and gasoline along with countless other chemicals. In many cases, this highly polluted water spills directly into watersheds.
Maintaining areas in their naturally permeable state may eliminate the need for retention and drainage systems as storm water can be absorbed directly into the ground. Natural remediation can occur to naturally remove pollutants as water seeps into natural aquifers.
