Expansion Board Caps
Expansion Board Caps provide clean, sharp lines for sealants. They eliminate the difficulty of removing wooden formers.
Zip Joints are easily installed joint formers designed to provide positive control of transverse construction or expansion joints. The two-part assembly is designed to permit removal of the top portion after the concrete has hardened, thereby creating a clean, neatly defined void for application of caulk or sealant when specified.
