A waterbar and a waterstop are both used in construction to prevent water infiltration in concrete structures, but they serve slightly different purposes and are used in different contexts. A waterstop is typically installed in joints within concrete structures, such as construction joints, expansion joints, and control joints. Its primary function is to prevent water from penetrating through these joints, ensuring the structure remains watertight. Waterstops are commonly used in applications like basements, tunnels, and water treatment plants

Waterbar

On the other hand, a waterbar is generally used to manage surface water flow and prevent erosion, particularly in road construction. Waterbars are physical barriers that redirect water off the surface of a road or trail to minimize damage from runoff. They are often used in unpaved road construction to maintain road integrity and prevent ruts and washouts. While both waterbars and waterstops are crucial for water management, they are used in different contexts and serve different specific functions in construction and infrastructure maintenance.
