Firth PorousPave® is one of the paver options in the Firth EcoPave® System. The paver has a very open texture which allows water to filter through it to the underlying drainage medium. Porous nature of the paver allows water drainage. PorousPave® is suitable for paths, patios, light to medium residential traffic areas and public footpaths.
