Which joint is made with two steel anchorages and a neoprene seal?

• A. Compression joint seal
• B. Pourable seal
• C. Strip seal
• D. Cellular joint seal

Answer: (C)

In this type of joint, a continuous neoprene strip is held in place and sandwiched between steel anchorages on each side. The two steel anchorages keep the strip securely positioned and prevent extrusion as the joint moves, while the neoprene provides a flexible, watertight seal that can accommodate movement without cracking. This combination—neoprene seal plus two steel anchorages—is what defines a strip seal joint. Other joint designs use different filling methods: a compression seal relies on a material that’s squeezed into a groove, a pourable seal fills the joint with poured material, and a cellular seal uses foam or cellular material inserted into the joint. None of these employ a neoprene strip anchored by two steel rails, so they don’t match this construction.
