Oldroyd Xv Black Cavity Drainage Membrane
BBA approved
Enhanced UV resistance
'X' pattern makes it easy to cut and fold
Oldroyd Xv Black is a studded black polypropylene cavity drainage membrane. It can be used to line and waterproof internal floors and walls in the same way as its sister product, Oldroyd Xv Clear. However, Oldroyd Xv Black benefits from enhanced environmental credentials as it contains a minimum of 56% recycled plastic. Because this is incorporated between two layers of virgin plastic using Oldroyd's novel multi-layer-technology, this is achieved with no loss of product performance.
Oldroyd Xv Black also benefits from enhanced UV resistance, allowing it to be used as an externally-applied secondary drainage layer in new-build basement waterproofing applications.
Typical applications include:
Basement and cellar waterproofing (BS8102 Type C)
External drainage layer (basement waterproofing)
Tunnel & arch waterproofing
Covering damp & contaminated walls
Covering damp & contaminated floors
Radon protection
When used as a basement waterproofing system, Oldroyd Xv Black should be used in conjunction with Aquadrain perimeter drainage channel and the Sentry Sump System.
Oldroyd Xv Black can be used to provide full radon protection; as defined in BR211 (call our technical department for details).
BBA approved
Semi-transparent
'X' pattern — easy to cut and fold
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.
Oldroyd Xv Clear can be used to provide "full radon protection" as defined in BR211 (call our technical department on 01403 210204 for details).
On floors, Oldroyd Xv20 is sometimes used instead of Oldroyd Xv Clear to provide a higher flow capacity behind the membrane.
On walls where a plaster finish needs to be applied to the membrane. use Drybase LP Plaster Membrane.
