• Permeable Paving consists of a pavement with a surface of solid concrete Paver Blocks designed with small openings that create permeable joints. The openings typically comprise 5% to 15% of the paver surface area and are filled with highly permeable, small-sized aggregates, instead of sand.
  • The permeable joints allow water to pass through the surface – between each block – and into voids within the underlying coarse aggregate, permeable sub-base. The spaces among the aggregates store water, enabling infiltration into the soil subgrade rather than generating surface runoff. The paver joints provide 100% surface permeability.
  • Permeable Paving with Paver Blocks is highly attractive, durable, easily repaired, requires low maintenance, and can withstand limited vehicle loads. 
  • Permeable Paving reduces stormwater runoff volume, rate, and pollutants.
