Crack Control Helicoidal Bars

Helicoidal Bars are available in 3m lengths in either a 6mm or 8mm overall diameter. They are used for reinforcing bed-joints to enhance lateral loading resistance in new and existing buildings. Helicoidal Bars can also be used to repair many structural defects in existing masonry by using repair strategies like over-pinning with ring beams and general crack stitching repairs. When using as a stitch repair, the helicoidal bar must be inserted 500mm past the outside of the crack, if the crack were to be less than 500mm from a corner or an opening then the bar must be returned round the corner by at least 100mm.
