Corrosion Protection and Conservation
Rowan Technologies has a wealth of experience in the protection and conservation of both historic and modern buildings both in the UK and further afield. We are advisers to English Heritage and have been involved in the conservation of many of the UK's most prominent historic buildings.
Cathodic protection (CP) is a method of controlling corrosion in metals embedded in stone, concrete and masonry by suppressing the electrochemical corrosion reaction. One of the advantages of CP is that it can provide protection without changing the immediate physical environment of the structure. By its nature, CP provides the optimum electrochemical conditions for the material being protected, thus preserving the visual appearance of the structure.
Rowan Technologies are experts in CP systems, having installed and maintained systems on a large number of prominent historic buildings and structures around the UK. We can provide custom designed systems for virtually any application, from the smallest monument to the largest cathedral.
We can also supply systems for more modern buildings as well as refurbish and recommission the electronics of third-party CP installations.
Rowan Technologies have extensive experience of both historic and modern concrete structures. We offer a comprehensive concrete inspection and consultancy service ranging from testing carbonation depths to preparing and costing repair and conservation strategies.
With extensive experience of both contemporary and historic structures, Rowan Technologies provides a comprehensive specification, monitoring and inspection service for all types of metallic roofs (lead, stainless steel and copper). During collaborative research projects with English Heritage, a chalk-rich coating (patination cream) supplied by us has been developed for protecting the underside of lead roofs from corrosion.
