This concrete pond built in 1980 required a complete overhaul due to an ongoing issue with a stubborn crack.
The pond firstly needed to be emptied and cleaned. The pond had only a small amount of water in but had years and years of pond sludge. Old plants and sludge were composted and the pond was hosed and scrubbed down. The leak was the next thing that needed to be dealt with. As the pond is concrete based any crack needs to be opened to stop it from spreading. After the crack was bolstered and grinded open an aquatic epoxy filler was used, this would rebuild the gap created. A final layer of pond sealant was used to finish the job and to ensure the pond was watertight. A complete re-paint of concrete sealer was then done to ensure the older concrete was also watertight.
