Gravel Grid 500mm x 500mm x 68mm

FirmGround70 gravel grids are ideal for grass and gravel infill, and are designed to be used for driveways, car parks, pedestrian areas and access roads; this ground mat can withstand up to 240 tonnes per m2 when filled. It's designed to allow water to drain away whilst pockets at the base retain some water. This prevents grass from getting waterlogged or dying through lack of water, and can help improve drainage.
