They are primarily used for reinforcing bed joints to enhance lateral loading resistance in new and existing buildings. The 3 metre helicoidal Bars can also be used to repair many structural defects in existing masonry by using repair strategies like over-pinning with ring beams, general crack stitching repairs, lintel failures and re-tying (disconnected and unconnected) solid or cavity masonry panels.
They can also be used to remedy a lot of structural defects in existing masonry. This is done by using repair strategies like general crack stitching repairs, overpinning with ring beams, lintel failures and re-tying (disconnected and unconnected) solid or cavity masonry panels.
