Larger 15.7 x 15.7 inch tiles make this interlocking drainage mat quicker to install than smaller mat systems, since a 24-piece box covers more floor with fewer pieces to snap together. Each black polypropylene tile is 0.7 inches thick, giving it enough rigidity to support vehicle weight and heavy rolling equipment in garages and workshops without flexing or cracking. The raised grid surface drains water and oil away from foot level, keeping the mat non-slip even when the floor beneath stays wet, which suits car repair bays, garden sheds, and covered outdoor spaces. Tiles connect edge to edge through built-in locking tabs, so no adhesive or separate hardware is required, and the layout can be reshaped to fit odd-sized rooms. At about 26.46 pounds per 24-piece box, this drainage flooring is built to handle long-term, high-traffic use.
