Following a window replacement programme four years earlier, these calcium silicate brick council houses were suffering from masonry shrinkage and cracking and sagging of the lintels above the windows.
To undertake a full lintel replacement programme involving removal of brickwork and the installation of stainless steel angles above all windows. Remove all cracked brickwork and rebuild with new bricks. Very disruptive to occupants and the fabric of the buildings; long projects times. Cost: £20,000 per house, on average.
To create new lintels, using the existing brickwork, by bonding stainless steel HeliBars into channelled-out mortar beds above each window. HeliBars and brickwork combine to form masonry beams that support and evenly distribute the loads. Helifix crack stitching stabilised the masonry and cracks were repaired with matching mortar. Benefits Cost was an average £3,000 per house on over 85 houses saving £17,000 per house. Visually unobtrusive as all taking down and rebuilding was avoided. Minimal disruption to building fabric and occupants.
