Oldroyd Cavity Drainage Membranes
The Oldroyd range of Cavity Drainage Membranes are manufactured in Norway under an ISO9001 / 14001 quality and environmental management system. They are produced from high-strength polypropylene using a special, temperature-controlled manufacturing process. This results in an exceptionally straight, tough membrane which does not suffer from the "banana-ing" and "rucking" which cause problems when installing other cavity drainage membranes.
Multi-layer Technology
All Oldroyd membranes are produced using Oldroyd's multi-layer technology technique which increases membrane strength and, in many cases, allows the use of 49-70% recycled plastic with no loss in performance. Membranes containing recycled plastic are denoted with a star or hash in the list below.
Membrane Range
The Oldroyd range of cavity drainage membranes is based around a range of core membrane products, supplied in rolls of varying sizes:
*Denotes membranes featuring 49-70% recycled material.
#Denotes membranes featuring 56-70% recycled material.
Accessories used in conjunction with Oldroyd membranes include the Aquadrain drainage channel and the Sentry sump system.
Applications
Oldroyd cavity drainage membranes can be used for a wide range of waterproofing an civil engineering applications including:
