We provide expert refurbishment solutions across a range of asset types and materials. Our aim is to extend asset lives to keep network systems operating. These produce significant savings in time, cost and GHG emissions when compared with full asset replacement.

We have readjusted our focus to think differently about existing asset capacity and how we can maximise and minimise our carbon impact, by offering re-life solutions rather than tearing a structure down to build new ‘high carbon’ alternative.

We are adept at providing refurbishment solutions across a range of reinforced concrete, steel or glass-coated structures. These solutions can be characterised as the low embodied carbon option and the most affordable, without compromising asset serviceability.
