7 mm Wall Stitching Bars.

7 mm x 1 m wall stitching bars restore strength and stability to cracked masonry and brickwork panels. Our 1m long 7 mm diameter stitching bars are the heaviest helical reinforcement rods suitable for standard 10 mm high mortar-bed joints. The additional mass of stainless steel gives the rods extra strength to perform better than the standard 6 mm products. These 7 mm spiral-shaped rods are in stock, sold in packs of ten, and available to buy at low trade prices.

Installing Stitching Bars in a Wall.

The helical-shaped bars fit into horizontal slots cut into mortar joints, which stretch 500 mm on both sides of a crack. Use WHO 60 grout to bind them inside the opening. The polymer-modified grout grips the helix and bonds the reinforcement firmly within the slot.

How do Wall Stitching Bars Work?

When grout-bonded helical bars bridge fractures in masonry, they absorb point loads and disperse them along the 1 m long helix length. A succession of stitching rods running the length of the fracture produces a reinforced region that enhances the wall's tensile, shear and flexural strength.

Our 7 mm bars conform to BS EN 845-1 for reinforcing existing walls. A single grout-bonded 7 mm bar resits an axial load of over 9.5 kN. Fitting two rods in one slot boosts the resistance to 17 kN. The reinforcing bars restore a wall's strength and increase its resilience to fracturing.
