Application:  Stitching Tie
--- 1/4" x 40" Stainless Steel Helical Tie

Masonry Wall - repair image.Helical stitching ties, with double the strength of rebar, are used as reinforcement bars to repair and stabilize cracked masonry.

Masonry Wall - repair image.The crack stitching method rejoins the fractured segments of the wall and disperses the building load across the structure while providing resilience against further cracking.

Cracks in building walls aren’t just unsightly, they can be warning signs of structural problems.

Cracks in brickwork occur when there is a build-up of stress in the wall.

Stress may be caused by normal thermal or moisture movement or by support failure.  In either case, once the cracks in brick or block are stitched, the stress is relieved.

 

 

Stitching Bar - installation:

To reconnect the facade, the wall is strapped or stitched 20” on both sides from the center line of the crack.

Horizontal mortar joints are routed out 1-½” deep, cleaned out and filled 2/3 deep with FX263 repair mortar - a polymer modified grout that is specifically formulated to bond with the stitching bar.

Together, they form a HD seal within the joint that increases both the tensile shear and flexural strength of the damaged brickwork.

The stitching tie is pressed into the mortar (right), followed by a troweling of the FX263 mortar to fill the joint.  By virtue of the continuous deep-helix channels, the bar forms a bond within the grout to strap the brickwork on both sides of the crack. The repair is inconspicuous and preserves the appearance of the structure.

Masonry Wall - repair image.Crack Stitching at Corners:

The stitching bars may be pre-bent at 90 degrees so that they can be used as concealed straps for stitching cracks on the corners of buildings.

A series of helical bars, bent at right angles, are placed into routed horizontal mortar joints and bonded with FX263 repair mortar.

The bars form layers of concealed reinforcement, wrapping around the corner to improve support and reinforcement  the wall.
