PROTECTS THE WATERPROOF
MEMBRANE & DRAINS THE WATER BUILD UP
Protection Boards
PRO-DRAIN is a 1m x 2m x 5mm polypropylene board comprising of 2 layers, one on top of the other spaced and joined together with ribs. The ribs are 5mm in height and run the full length of the board at 4mm intervals creating a set of adjacent 4x5mm vertical channels. 1mm horizontal channels are cut through the top layer of the board across the full width of the board perpendicular to the vertical channels every 22cm leaving the bottom layer intact. The horizontal channels are deep enough to allow water to pass through the board into the vertical channels and flow to the drainage outlet.
