Strengthening Masonry Arches Bridges Tunnels & Buildings using Grouted Tie Bars

Masonry and brick arches, tunnels, bridges, and buildings are strengthened using retrofit tie bars grouted through thick or multiple-layer structural walls. This video shows the installation process for inserting grout bonded helical ties as part of an engineered strengthening scheme that is enhanced by the provision of a matrix reinforcement cage. Grout ties are also deal for use to retain and structurally repair a brick or masonry wall that is coming away from the main structure of a building.
