Repairs to leaking horizontal and vertical seams can be achieved using leak repair profiles, which is a method devised to enable our field service engineers to effect long term leak repairs. The method has been developed by Tower Systems over many years improving the profile design & installation and by the use of a superior butyl tape of high adherence & resilience. Where it is not possible to install profiles due to access restrictions the repair can be attended to by splitting & caulking the joints with fresh mastic.
