Waterstops in concrete construction are typically installed by which trade?

• A. Concrete Contractor
• B. Roofer
• C. Mason
• D. Carpenter

Answer: (A)

Waterstops prevent water from migrating through joints in concrete, so they have to be placed as part of the concrete pour and joint detailing. This work sits with the concrete contractor, who handles formwork, reinforcement, and embedded accessories during placement and finishing. The roofer’s focus is roof coverings and flashing; a mason builds with masonry units; a carpenter handles wood framing. So, the concrete contractor is the one who typically installs waterstops.
