Oldroyd Gtx Range Geotextile Cavity Drainage Membranes
Standards & Accreditations
BS EN 13967 SINTEF
The Oldroyd Gtx range consists of cavity drainage membranes with a geotextile mesh welded to one side (often referred to as geocomposite membranes or geocomposites ). The geotextile mesh filters out the fines in the groundwater, preventing them from causing blockages in other areas of the drainage system, making Oldroyd Xv 20 ideal for basement waterproofing and drainage applications.
The Oldroyd Gtx range of membranes are often used when waterproofing earth-retaining structures such as basements and retaining walls. In these situations they are applied externally and are therefore generally used only on newbuild projects. Other solutions are available for the basement refurbishment projects which can be applied internally.
Oldroyd Gtx 20 used as drainage layer for basement waterproofing
Oldroyd Gtx membranes are usually used as a secondary drainage layer to protect a primary waterproofing system. When used in this way, Oldroyd Gtx membranes are effectively used to replace protection boards, but with the added advantage of diverting the majority of groundwater away from the primary waterproofing system avoiding the need for drainage aggregates and allowing excavated soil to be reused as backfill. Suitable products for use as a primary waterproofing system include:
Vandex BB75 E
Vandex Flexbit Range
This dual layer approach lessens the stress put on the primary waterproofing system, reducing water ingress caused by possible imperfections in the application of the primary waterproofing system and / or structural movement.
Oldroyd Gtx membranes can also be used as ground pressure relief fin drains in civil engineering applications and as vertical edge drains around pavements and carriageways.

Aggregate over Oldroyd Geotextile Membrane
Paving being laid over aggregate and membrane
The Oldroyd Gtx range of membranes can be used as horizontal drainage layers in a wide range of applications including:
Roof decks / terraces
Contains 49% Recycled Plastic
The Oldroyd Gtx range of membranes contain a minimum of 49% recycled content as defined in section 188.8.131.52 of ISO 14021. Where quality and availability of recycled plastic allows, up to 70% recycled plastic may be used. By utilising Oldroyd s multi-layer technology this is achieved without any loss of product performance.
