Permeable Pavements - Overview

A permeable pavement is one that is designed to allow surface water to percolate through the pavement surface and underlying structural layers. These pavements are generally categorised into one of three classifications, according to how surface water is managed within the system.

Permeable pavements can be used on most sites and are able to offer numerous benefits, without requiring any additional space above what would typically be required by the development. However, their use in areas that are expected to receive high silt loads should be avoided, due to the risk of premature clogging of the pavement surfacing.
