Grout-filled socks combined with threaded bars are gaining popularity to form a strong chemical and mechanical bond for securing external walls to hollow concrete floor slabs, for stitching cracked solid and multi-lead walls, for stabilizing rubble-filled walls, and securing unstable parapet walls and arches. This technology is ideal where high levels of performance are required in bending for heavy duty, high load applications. The demonstration session will provide an overview of this fast, efficient, proven installation technique.
