Austenitic stainless steel reinforcing bars Fully concealed, non-disruptive repair system Cost-effective and more reliable than crack injection methods HeliBond cementitious grout is injectable and rapidly produces high compressive strength HeliBar rods and HeliBond grout produce excellent bond strength within the masonry HeliBars combine great axial strength with flexibility

No additional stresses introduced Tensile loads redistributed along the masonry Masonry remains flexible enough  accommodate normal building movement Minimises changes of the crack developing Reduces likelihood of further cracking nearby Avoids the need for costly and disruptive taking down and rebuilding Permanent and sympathetic solution

Points to note

A. Where two or more cracks are close together these may be stitched using one continuous length of HeliBar which must be long enough to extend 500mm beyond the outer cracks. E.g. if there are three cracks, each 250mm apart, then the overall length of HeliBar required would be 1.5m.	C. Ensure that no mortar is left attached to the exposed brick faces within the cut slot in order to ensure a good masonry/grout bond.	E. As standard, slots should be 10mm wide to accommodate the 6mm diameter HeliBar. For thin joints use 4.5mm HeliBar.
B. The horizontal slot, normally the mortar bed, can be cut using a twin diamond blade chaser with vacuum attachment, and angle grinder or a mortar chisel.	D. Prepare the slot with HeliBond Primer or thoroughly wet the slot with clean water.	F. HeliBond grout is the recommended bonding agent. PolyPlus resin is used for smaller jobs and where loads are to be rapidly applied.
