FilterPave® porous pavement system is nearly twice as porous as pervious concrete and maintains the highest sustainable void space of any porous pavement system.

Stormwater permeability
The stormwater permeability of the FilterPave® system is similar to the seepage performance of an open-graded base course. Rainwater is absorbed quickly and can seep directly into the ground or be redirected into the drainage facilities (e.g. canal, retention basin, or rain water storage vessel).

Easing the burden on drainage systems
With FilterPave®, higher-level drainage facilities are relieved by the storage effect and the favourable run-off coefficient reduced surface runoff).

Surface de-sealing
Thanks to its open-pored structure, the FilterPave® system reduces surface run-off, (Covering Class 4) permitting the use of smaller drainage features.

Pollutant bonding / degree of absorption
The FilterPave® system, with its filter effect, not only permits near-natural rainwater infiltration, it also absorbs hydrocarbons such as engine and gear oil and fuel residues. The structure of the FilterPave® system prevents the spread of oily substances on the surface and reduces the risk of large-scale contamination. Biological processes, such as the conversion of hydrocarbons into harmless by-products, can be positively influenced.

FilterPave® surfaces do not require any further sealing until 5-10 years. Similarly, the risk of freeze-thaw damage and the need to repair cracks and replace wear courses is very greatly reduced when compared to conventional pavements. Like other open-pored surfaces, FilterPave® helps reduce the need for road salt when there are frozen ground conditions.
