Liverpool City Council, as “engineering operations” and “change of use” permission was required.

The materials include a root barrier, Oldroyd Xv Green Xtra drainage membrane. The root barrier prevents any root penetration to the underlying waterproofing. The drainage membrane retains rainwater for the plants, and perforations prevent waterlogging. The filter fleece laid on top then retains the soil and plants, but lets plant roots penetrate to the water stored below. The Green Roof…

The interior walls brochure examines the use of Oldroyd membranes to cover damp and contaminated walls. This approach has a number of advantages over traditional waterproofing methods, for example minimal surface preparation is usually required and less dependence is made on the quality of the underlying substrate. Specific applications referred to in the brochure include: Barn conversionsCellar RefurbishmentNewbuild Basement Waterproofing…

27th August 2008 – Two new fixing guides for green roofs are now available for download from this website: Fixing guide for pitched green roofsFixing guide for flat green roofs The guides cover the key steps required to construct a green roof using the Oldroyd Green range of drainage membranes which contain 49 – 70% recycled material. In recent years…

Oldroyd’s new range of “green roof” membranes has been officially launched in the UK. The membranes feature Oldroyd’s unique multi-layer technology to produce a “greener” membrane for green roofs. Each of the membranes is made up of three layers with the inner layer consisting of 50% recycled material. The outer layers are formed from a rubberised plastic, providing a safer…

To some extent all green roofs can be said to encourage biodiversity as they provide a habitat that supports life-forms that would be unable to survive on a more traditional roof structure. Biodiverse roofs (also known as brown roofs or rubble roofs) share many of the qualities and benefits of green roofs, but differ in that they are designed to…

The environmental benefits of turf and green roofs are widely recognised, while roof gardens and roof terraces provide much-needed outdoor space in urban areas. Due to the high degree of insulation that they provide, green roofs are known for their ability to provide an extremely constant temperature throughout the year.

Knowledge of green roof construction methods and the benefits of incorporating them in building design is steadily becoming more widespread in the UK. Unlike pitched green roofs, flat green roofs can either take the form of extensive (consisting of a thin layer of turf or sedum matting), or intensive (characterised by a greater soil depth that can even accommodate shrubs…

The benefits of green roofs are becoming increasingly understood by those in the UK construction industry. Waterproofing systems for pitched green roofs tend to be simpler than those for flat green roofs, as “pooling” of water has less potential to cause a problem. Nevertheless, as with all waterproofing products, the success of the system is dependent upon the quality of…
