Hydro Scheme Construction

2004 saw us launching into Hydro Schemes as a principal contractor. After many years of working on schemes as a sub contractor, it was time to use the skills we had accumulated. Since then we have been systematically decorating the landscape with some impressive schemes that have been both challenging and interesting in location and build. As it stands, we have successfully completed over 50 schemes to our renowned quality and high standard.
