Permeable Pavers

Much of current development leaves a high percentage of land surfaces with impermeable materials. Urban areas typically have between 75-100% impervious surface cover, which results that only 15% of precipitation infiltrates the ground, and full 55% remains on the surface as storm water runoff. Permeable interlocking concrete pavements are surfaced with unit block pavers that allow for an expanded joint between units. The joint is then filled with open-graded aggregate, making the pavement surface permeable.

This type of paver installation offer a multitude of possible benefits:

• Water absorption by the soil
• Increased recharge of groundwater
• Reduction of downstream flows
• Stream bank erosion
• Elimination of flooding of paved areas

Primary goal is to reduce runoff volume on site and find beneficial uses for the water as opposed to utilizing storm drains.
