Ardex - UD 150 Thin Drainage Mat Underlay - 1 m x 2 m (8 pack)

ARDEX UD 150 is a thin (9 mm), mesh-reinforced plastic drainage mat for use under directly bonded tile surfaces. A 6 mm drainage channel allows water to pass freely beneath the tiled surface, speeding drying after rainfall and reducing the likelihood of efflorescence buildup. ARDEX UD 150 is loose-laid over the membrane, separating the tiled surface from any substrate movement. In addition to its drainage capabilities, ARDEX UD 150 is ideal for soundproofing, providing up to 16 dB of improved noise reduction.
