The function of a water stop in concrete joints is primarily to prevent water penetration. Water stops are materials designed to create a watertight seal at the joints in concrete structures, such as between walls and floors or at construction joints. They are crucial in areas exposed to hydrostatic pressure, where water can seep through joints and cause structural issues or damage.

By effectively blocking water, a water stop helps maintain the integrity of the concrete structure, preventing leaks and potential water damage to both the concrete and any adjacent materials or spaces. This is particularly important in foundations, basements, and other areas where moisture control is critical. The use of water stops ultimately contributes to the longevity and durability of the concrete elements being protected.
