Porous Paving Materials

Permeable Pavement

Created at: 23 Jan 2017

Description

Any porous material is highly suitable for paving: for example, open cell concrete blocks, grass concrete pavers, woodchips, shells or gravel can be used as paving materials. Precipitation can infiltrate into the ground without any appreciable difficulty; the percentage of openings varies from around 15% to 40%. This type of paving material can be used for such purposes as footpaths, playgrounds, fire service roads and central reservations, for aeration around trees, as edging for paving materials and in verges. For roads and car parks that are used extensively, paving materials such as porous clinkers, open-joint clinkers, open paving patterns, gravel or shells can be used.

Porous paving materials cannot be used for intensively used roads or car parks owing to the risk of pollution, and because those materials cannot bear large loads.
