ποΈ Project Completion | Llyn Madoc
We recently completed a particularly challenging project at Llyn Madoc, carrying out repairs to water-damaged masonry within the former mill house water wheel pit.
Designed, planned, and delivered by BrynBuild, the project required specialist engineering expertise, close coordination with Natural Resources Wales (NRW) and the necessary permits to carry out the works in this challenging river environment.
Due to the location of the pit and the condition of the masonry, much of the work had to be carried out underwater by a specialist dive team. The works included the removal of loose masonry, failed mortar, silt and debris, followed by localised masonry repairs, specialist grout installation and repointing.
A specialist river rescue team was also on standby throughout the works to support the safe delivery of the project.
Despite the challenging conditions, the project was successfully completed in just seven days, demonstrating the BrynBuild team's ability to coordinate specialist skills and adapt to complex working environments.
