The use is intended to be temporary, with the mats being reusable. The mat, in its basic construction, includes a flat plate-like structure having a thickness and planar extent and an opening defined in the flat plate-like structure which extends in the thickness direction and is dimensioned to receive a lifting device for lifting and transporting the mat.
