London South Bank University, London Coating systems used: Elastaseal™,
London South Bank University (LSBU) was established in 1892 and is home to over 23,000 students making this one of the oldest and largest universities in central London.
The University is currently refurbishing the campus to allow it to continue to provide the best student facilities possible. This includes the refurbishment of a number of weather damaged roofs.Over time the existing flat asphalt roofs were cracked, crazed and blistered by seasonal weather. The poor condition of the roofs resulted in leaks that caused disruption to the University operations. The existing roofs had a failed silver solar reflective coating that was badly degraded. Refurbishing with asphalt was not a desirable option and the University required a long- term solution to the problems it was experiencing.
Tor Coatings, a leading specialist in roof refurbishment, conducted a survey of the existing roofs. All surfaces were inspected to assess the soundness of existing substrates and coatings. This was to verify compatibility with any proposed waterproofing coating system. After a detailed inspection ElastasealTM 15 was recommended as the best solution. This system provides a 15 year 100% waterproof membrane.
One of many benefits of using ElastasealTM is that the system is cold liquid-applied. This allows installation to be carried out, without the risk of fire due to the cold nature of the product. More conventional roofing substrates such as asphalt require the use of hot works, posing a potential fire risk. As ElastasealTM is a cold liquid product there are no associated fire risks. The ElastasealTM system works by seamlessly encapsulating the roof, creating a new membrane that is not only completely waterproof but also allows the roof beneath to ‘breathe’ due to its vapour permeability. This ensures the roof remains leak- free for up to 25 years depending on the level of specification (BBA approved system is available).
The ElastasealTM 15 year system was applied to the roofs by T.R.C Service Group Ltd, a member of the Tor Partners scheme. This scheme assures the client that ElastasealTM is applied by a trained professional contractor correctly, safely and efficiently in manner compliant with the manufacturers specification.Back to case studies
