The Vulkanix Rubber Grass Mat is 23mm (thick) x 1.0 meter (wide) x 1.5 meter (long) and is a non-slip rubber mat. Ideal for installation on heavy traffic grass areas and walkways. The mat also protects against erosion. The Grass Mat has been designed to allow grass to grow through the large and small holes, helping to keep that natural green feel to any area.
