Deck sawing, also known as flat sawing, is used to cut horizontal flat concrete surfaces such as floors, bridge decks and pavement. Deck saws feature a diamond blade that is mounted on a walk-behind machine that requires only one operator. Deck sawing is the perfect solution for making penetrations or openings in concrete floors to access and repair a broken water pipe or sewer line. Other typical uses for flat sawing is sawing for new machine foundations, highway patching and plumbing trenches. Concor can also remove and re-pour.
