Our waterproof structures use a 900gsm PVC fabric. The white fabric is supplied with a 10 year warranty and has an expected life-span of 30 years plus, while the coloured fabrics have a 5 year warranty and a life span of 12-15 years.
All of our PVC tension structures are designed to withstand a wind loading of 110mph and a snow loading of around 22kg of snow per m² (approx 100mm deep).

Where a crane is required for installation we would need photos and dimensions of the site and its access points. This will help us establish which type of crane is required and if it will incur any additional costs.
