• Helical bar is manufactured from 304 austenitic stainless steel, (316 available upon request)
• Non-disruptive repair method
• Cost effective and more stable than other repair systems
• Helical bars and SureGrout or SureBond Resin provide excellent bonding characteristics within the masonry
• Helical Bars have a superb combination of axial strength and flexibility
• Absorbs further localised stress
• Minimises the likelihood of further cracking
• Eliminates the need to rebuild a wall
• Permanent repair
• A fast, cost effective and economical solution
• No special skills required for installation

Installation Characteristics: 

Vertical spacing every 4 to 6 brick courses. (300 – 450mm)

Notes:

• Bar to extend 500mm beyond the end of any opening or crack.
• Where cracks are within 500mm of corners or reveals bar is to be bent and bonded around the corner to recommended distance.
• When joining SureTwist Bar, ensure that it is overlapped by at least 500mm.
• Crack-stitching cannot cure the cause of the crack. Crack-stitching can only stabilise the symptoms of the cause.
• Always seek the advice of a structural engineer before undertaking any structural repair
