Our experience and expertise lie in almost 4 decades of experience, in manufacturing, quality control, R&D, troubleshooting and testing. We have been electronically testing flat roof coverings for leaks in mastic asphalt , felt and single ply for over 20 years.
We also pioneered the concept of integrity testing in 1987, since when we have worked on major developments such as Broadgate and Canary Wharf in London, Bluewater and the latest Shopping Centre, Westfield (plus a host of others).
In our time we have tested roofs to over 200 new Sainsbury stores, plus a large number of Tesco and other brands.
We are constantly developing new procedures to meet new challenges and will not test a membrane or roof system we consider to be incompatible. Warm roofs, for example, particularly where the waterproofing is asphalt or concrete, do not lend themselves at all to electronic testing unless special measures are taken beforehand, on which Thornton Consulting can advise on request.
Electronic testing can also be a valuable aid in condition surveys of existing roofing stocks, thus enabling repairs to be accurately targeted and potentially prolonging the life of the roof.
