Firth Grass Pavers combine the natural and welcoming look of a grass lawn with the strength and durability of a paved surface. Grass Pavers have widely spaced openings which allow grass to grow through. Part of the Firth EcoPave™ Permeable Paving Range, the permeability of the Grass Paver is subject to top soil and type of grass. Ideal for driveways or parking areas and light vehicle traffic areas.
