Bigger 15.7 x 15.7 inch tiles mean fewer pieces to snap together when covering a garage or workshop floor with this 24-piece interlocking drainage mat. Each gray polypropylene tile is 0.7 inches thick, giving the mat enough rigidity to support vehicle weight and heavy equipment without flexing, while the raised grid surface channels water and debris underneath to keep the top dry and non-slip. Tiles connect through molded locking tabs, so no adhesive or separate hardware is needed, and the modular layout can be reshaped to fit odd corners or extended with additional boxes. This mat suits car repair bays, garden sheds, and covered outdoor spaces where a stable, water-resistant floor makes daily work safer. At about 26.46 pounds per 24-piece box, it's sized for straightforward, one-session installation over a mid-size footprint.
