Drainage membranes are utilised as supplementary layers in various waterproofing systems, functioning as an anti-capillary obstruction in buried structures or drainage systems. Using drainage membranes in walls offers the following benefits: swift and effortless installation.
On average, it is recommended to replace the reverse osmosis membrane every 3-5 years. However, if the membrane continues to produce high-quality water, it could potentially be used for more than five years.
Our staff are able to provide guidance for projects of all sizes, whether you require some general advice about damp or waterproofing, or support with technical drawings and specifications.
