The Interlocking Concrete Pavement Institute (ICPI) released “Tech Spec 23: Maintenance Guide for Permeable Interlocking Concrete Pavements (PICP).”
“PICP is a durable, cost-effective solution for compliance with national, state/provincial and municipal stormwater regulations. The surface consists of solid, durable concrete pavers with small, stone-filled joints that allow water to flow into highly permeable, open-graded bedding, base, and subbase aggregates. The spaces among the aggregates store water and enable infiltration into the soil subgrade rather than generating surface runoff. PICP is an excellent option for freeze thaw climates.”
