Oldroyd Xv Clear is a semi-transparent, studded cavity drainage membrane manufactured from polypropylene. It is specifically designed for application to damp / contaminated internal floors and walls, and is particularly useful in basement waterproofing / conversion applications. Oldroyd Xv Clear is applied to walls and ceilings by means of special sealed fixing plugs (Oldroyd Brick Plugs), while on floors, there is normally no need for any form of fixing. The semi-transparant nature of Oldroyd Xv Clear makes it easy to locate suitable fixing points (e.g. avoiding soft mortar beds).
