Ensuring Cladding Safety

Recent news events have shown how vital it is to investigate the condition and type of cladding used on buildings throughout the UK.

HTA can employ a variety of access techniques to access and survey a variety of cladding systems found on buildings. NDT is also used to reduce intrusive investigations as far as possible, this alongside our modern approach and our 30+ years of Experience has proved invaluable to our clients.
