These durable interlocking floor tiles are designed to provide an attractive and practical garage flooring solution. The tiles come in various colors so that multi-colored designs can be created. The tiles feature a beautiful diamond solid top shape with a grid underneath that allows air and water passage. These interlocking tiles are also suitable for basement flooring, trade show flooring and other portable flooring needs. The tiles are comprised of a non-toxic, high-impact polypropylene (non-rubber), which is a rigid, lightweight and strong material. They are able to withstand the high rollover weight of large vehicles including SUVs and pickup trucks. The rigidity and strength of the polymer from which the tiles are constructed allow for the tiles to be designed with a grid on the underside of the tiles. The grid design allows air and water flow to help prevent mold. Other types of garage flooring available in the market, such as rubber flooring or flexible PVC flooring, lack the grid design feature due to material constraints. Installation of these tiles is very simple as no special tools are required. They interlock together with a loop-to-peg system to create a "floating floor." So when installing the floor, it is important to leave a 1/2-inch gap minimum around permanent objects.
