The weight limits for Floorbit flooring are found below: • Synchrowood 8mm - 300kg • Synchrowood 12mm - 600kg • Floorbit 4mm - 100kg • Floorbit 5mm - 200kg • Ultraboden 8.5mm - 500kg • Waterblock 8.6mm - 500kg • Herringbone 12.6mm - 1000kg If the subfloor is prepared with a self-levelling underlayment, and for two reference points 2m apart, the maximum vertical deviation is 4mm and below (subfloor evenness), the weight limit for each flooring is increased by 50% respectively. While our flooring have been designed to withstand even higher loads, we arrived at these recommended weight limits after rigorous testing to identify the optimal weights.
