Our Grass Mats are of the highest quality. Manufactured in the UK, they are geo-synthetic, comprised of 100% recycled materials; and are designed to carry weights as high as 20,000 lbs. The purpose of these mats is to place equipment, vehicles, condors or heavy duty equipment on a grassy area without the weight and wheels of the vehicle or carts damaging the lawn. They do so, while allowing the grass access to sun and oxygen, preventing grass burns that would otherwise be created by plywood or dance floor. They are not meant for pedestrian traffic unless installed a week prior allowing the grass to grow through the mesh. The growth of the grass through the oscillated mesh is designed to increase traction and improve slip resistance allowing pedestrians to walk freely about.
