Oldroyd Xv Clear Cavity Drainage Membrane (2.08 m × 20 m)

Oldroyd Xv Clear is a studded clear polypropylene cavity drain membrane used to line and waterproof internal floors and walls.

Oldroyd Xv Clear is fixed to walls using special self sealing plugs (Oldroyd Brick Plugs with Seals). Because Oldroyd Xv Clear is semi-transparent, it is easy to locate suitable fixing points behind the membrane (e.g. avoiding soft mortar beds). The fixing plugs are able to accept No.12 screws – facilitating the application of plasterboard via timber battens or an aluminium framing system.

When used on floors, fixings are not usually necessary. Various types of screed and timber flooring can be applied on top of Oldroyd Xv Clear – contact our technical department for details.

Sections of Oldroyd Xv Clear can be joined using Oldroyd double-sided tape. Where a double-seal is required (e.g. radon protection) Oldroyd overseal tape can be used to provide an additional seal.

Typical applications include:

• Basement and cellar waterproofing (BS8102 Type C)
• Tunnel & arch waterproofing
• Covering damp & contaminated walls
• Covering damp & contaminated floors
• Radon protection

When used as a basement waterproofing system, Oldroyd Xv Clear should be used in conjunction with Aquadrain perimeter drainage channel and the Sentry Sump System.

Radon

Oldroyd Xv Clear can be used to provide “full radon protection” as defined in BR211 (call our technical department on 01403 210204 for details).

Floors

On floors, Oldroyd Xv20 is sometimes used instead of Oldroyd Xv Clear to provide a higher flow capacity behind the membrane.

Plaster Finish

On walls, where a plaster finish needs to be applied to the membrane Oldroyd Xp Plaster Membrane can be used.
