Manufactured from durable materials our black plastic mats are designed to be used on drive ways. The grids provide a stable surface and at the same time provide resistant to heavy loads such as vehicles. The grid features a cell structure which creates reservoirs for rainwater, which improves irrigation of the ground whilst protecting the grass from rapid drying. Each grid also has a built in anti – migration cell bottom lattice which is designed to prevent downwards gravel movement through vibrations and vehicle traffic.
