What Are Permeable Interlocking Concrete Pavers (PICPs)?
Permeable pavers (a.k.a. PICPs or Permeable Interlocking Concrete Pavers) are a system of interlocking concrete pavers that feature layers of varying-sized stone beneath, to allow for the filtration and free-flow of stormwater into an underground aquifer.
As the demand for ecologically-friendly green construction continues to grow, permeable pavers are becoming an increasingly popular choice for both commercial and residential applications here in Southwest Florida, and indeed throughout the country. The key to understanding how permeable pavers work lies in understanding that the pavers, themselves, are not permeable; they are simply one part of an entire subterranean system that allows stormwater to drain through the joints between the pavers.
The water that is drained through the permeable joint material is then subsequently naturally filtered through multiple levels of varying degrees of crushed stone, until it is redistributed back into the groundwater without the need for an on-site retention pond.
