Advantages
A diver completing underwater repairs
 |  |
At underwater sites, a diver examines and maps out the damage. Impurities and crumbling mortar are removed with a water chisel at 600-1000 bar or a high-pressure water jet. The actual repairs are then done by divers. Moulds are usually not necessary. Even large repair jobs can be done quickly and easily with the help of a shutter mesh. If moulds are used, they are lightweight and quick to install.
