Crack Stitching

Crack stitching bars provide a permanent solution for masonry repairs and cracked wall reinforcement to suit vertical, stepped or corner cracks in masonry. When tying cracks in face

brickwork, these high strength bars are grouted into slots cut into mortar beds, ensuring the reinforcement is discreetly concealed once th e mortar joint is pointed. Tensile forces are redistributed along the wall to dissipate load and minimise the risk of further cracking.

Cracks are repaired with no further damage to the wall, no costly or lengthy re-construction work

and without inconvenience to the building's occupants. The repair restores the structural integrity of masonry and provides resilience against further cracking.

Brick beam lintel reinforcement of brickwork above window & door openings. The system uses 3.5m helical bars to span windows and doors up to 2.5m wide.

Two mortar beds, separated by 450-900mm are reinforced, each with a pair of high tensile stainless steel 6mm diameter helical re-bars embedded into the wall with masonry repair grout.

The patented bars are encased 500mm beyond each side of the opening.

The reinforced bed joints form tendons that represent the upper and lower flanges of a brick beam or wall lintel. Utilising the surrounding masonry, one tendon carries compression and the other acts in tension. The reinforced brick beam lintel has a typical load carrying capacity of 2.6 tonne (BRE Calculations).
