Abstract

The present invention provides a ground cover mat that protects the terrain from a vehicle or the like. The ground cover mat is manufactured by molding recycled polyethylene plastic into a sheet-like mat, which is inexpensive, relatively light in weight, durable in harsh conditions and easy to cut. The ground cover mat includes a pattern of lugs on its upper and lower surfaces to provide a traction surface for the vehicle and to provide friction between the terrain and the ground cover mat.
