Wind Sound Barrier Installation Secondary Grouting Gravity Mortar

Gravity mortar is a specialized filling mortar developed for the installation of bridge deck ancillary works on passenger-dedicated lines. It is easy to use and simple to operate, quickly self-leveling and grouting through gravity action. It accelerates construction progress and enhances the fatigue resistance of wind barriers.
