Faster installs, stronger floors. ARDEX UI 740 FLEXBONE is a high load-bearing uncoupling membrane for large-format tile in heavy-traffic areas — its bone-shaped GripLock pattern delivers outstanding tensile bond, neutralizes substrate movement, and distributes heavy loads. It also doubles as a waterproof layer in bathrooms and wet areas, and now includes added ventilation channels.
