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

ARDEX UD 150 is a thin plastic drainage mat (9 mm), with reinforced mesh, intended for use under direct-adhesive tiled surfaces. A 6mm drainage channel allows the free passage of water beneath the tiled surface, speeding drying after rain and reducing the likelihood of efflorescence build-up. The ARDEX UD 150 product is placed loose on the membrane, which separates the tiled surface from any movement of the substrate. In addition to its drainage capabilities, the ARDEX UD 150 product is ideal for soundproofing, providing up to 16 dB of improvement in noise reduction.
