In liquid-bearing concrete structures, joints are where protective linings fail first. A monolithic film is asked to span a moving gap and stay bonded to both sides through thermal swings, settlement, ...

The spalled concrete joint repair preparation and installation process when using semi-rigid or sand-modified semi-rigid repair materials is not unlike the initial joint filling process. It’s ...
