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 Kit…

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…

To maximise biodiversity, a wide range of growing mediums will normally be distributed around the roof surface (usually sourced from the local area). In most cases, these are either left alone to allow the germination of wind-blown seeds, or alternatively, seeds collected from the local area are scattered over the roof area. Over time an ecosystem of plants and animals…

During the winter green roofs keep the heat in, and in the summer they provide a relatively cool environment. Green roofs also have the ability to soften harsh edges of buildings in sensitive environments, making them blend in with the surrounding area. Turf and green roofs provide habitat for insects and other wildlife. Where new buildings are built on greenfield…
