Engineered to reduce noise, vibration, and impact, the Interlocking Tile Flooring will take your home gym to the next level. Each pack contains twelve, 10mm thick, impact-resistant center rubber tiles to support any workout and fitness equipment style. Easy to install, the puzzle-style edges fit together smoothly and securely, only needing a sharp utility knife and straight edge to cut. The seams appear nearly invisible once connected. The tiles are safe to use indoors and out and can be laid loose, saving you from applying adhesive during installation. Additionally, these non-slip rubber tiles can create custom mats for weight rooms, basements, ski lodge flooring, and more.NOTE: If you acquired the Interlocking Tile Flooring prior to November 2023, please note that these tiles are not compatible with the earlier version.
