Waterstops are typically installed by which tradesperson?

• A. Architect
• B. Concrete contractor
• C. Carpenter
• D. Roofer

Answer: (B)

Waterstops are used to block the passage of water through concrete joints in structures, keeping slabs and walls watertight as they cure. The concrete contractor is the one who places and bonds the waterstop into the joint forms before pouring the concrete, ensuring a watertight joint. Architects specify the details of waterstops but don’t install them. Carpenters work with formwork and wood framing, while roofers handle roofing materials and flashing—not embedded waterstops in concrete joints. So, the concrete contractor is the typical person responsible for installing waterstops.
