One of the past projects we assisted with was the decommissioning of a building by Atomic Energy of Canada Limited. This project included the demolition of an interior concrete vault used for testing radioactive materials.
There were several factors contributing to the difficulty of this project. First, the vault’s three-foot-thick elmanite concrete (which weighs twice as much as ordinary concrete) walls and roof were lined on the inside and outside with ½” steel plates. Also, due to the radiation danger, all coolant and debris had to be tested before it could be removed from the building. With our diamond wire sawing, we completed this project in one-third of the time that would have been required by conventional hammering methods.
Atomic Energy of Canada was so impressed by the speed and efficiency of the vault removal that they assigned us additional wire sawing projects on the spot.
