Each tile measures 12”x12” including locking tabs. The useable surface area of the tile (not including interlocking tabs) is 11.5 x 11.5 inches. Thickness of 3/8” provides plenty of space underneath the tile to drain large volumes of water. Surface area of the tile is supported every 1-3/8” so tiles will be able to withstand even very heavy foot traffic. Every corner has provision for screws should the tile need to be fastened to the floor. Tiles are ideal when large areas need to be covered. Different color tiles can be used to create attractive color patterns. Ramps and corners are available to reduce slip-fall hazard and/or to achieve finished look. Assembled tiles can be taken apart for cleaning purposes or if they need to be re-used in another location.
