Ancon Staifix-Thor Helical Crack Stitching Kit

The Staifix-Thor Helical Crack Stitching Kit is the high strength, non-disruptive solution for the permanent repair of cracked masonry.

Features:

• This kit contains all the necessary components to permanently repair vertical or stepped cracks in masonry.
• Experts in the remedial market have designed the kit’s contents, guaranteeing the correct specification of reinforcing bar, grout and installation tools required for this application and the compatibility of all components.
• Stainless steel helical bars are chemically bonded into horizontal slots, cut in bed joints, which stitch across the crack. When installed, these bars evenly redistribute tensile forces over the reinforced area to stabilise the structure. On completion, the bars and the grout are concealed, retaining the original character of the wall.
• Cracks are repaired with no further damage to the wall, no costly or lengthy re-construction work and no inconvenience to the building’s inhabitants.
• This system is also suitable for rendered/plastered walls.
• Vertical spacing is normally every 4 to 6 brick courses (300-450mm), however this should be checked with the structural engineer.
• Where cracks are within 500mm from corners or reveals, the bar should be bent and bonded 100mm around the corner.
• If two or more cracks are close together, bars can be lapped - Laps should be at least 500mm and the bar should extend 500mm from the outer cracks.
