What to expect when we carry out wall tie replacement

Tie survey
A metal detector locates the existing ties and shows their pattern. Small holes are then drilled at sample points and a borescope passed into the cavity to see the tie condition, type and embedment. The holes are made good afterwards.
Install the new ties
New stainless ties are drilled and fixed to the specified grid, with closer spacing around windows, doors and the roofline. Sample ties can be pull-tested to confirm they are holding in your particular brick and block.
Deal with the old ties and make good
Old ties are isolated or removed where the report calls for it, cracked joints are raked out and repointed, and drilled holes are filled in matching mortar. A written note of tie positions and findings goes in your property file.

Repair options we may recommend

Partial rebuild of the outer leaf

If a section of the outer leaf has bulged too far to be tied back, it is carefully taken down and rebuilt with new ties built in as the work goes up. This is uncommon, and is usually limited to a gable top, a parapet or a panel under a window.

Best for: Outer leaf too distorted to tie back safely

Remedial tie installation

New stainless ties are drilled through the outer leaf into the inner leaf, then fixed by mechanical expansion or resin, depending on the masonry. They are placed to a set grid across each elevation, with extra ties around openings and at the edges. Holes are made good in matching mortar.

Best for: Walls where the original ties have failed or are missing

Do you cover King's Lynn?

Is the ground in Norfolk prone to subsidence?

Norfolk is chalk covered by glacial sands, gravels and boulder clay, with fen silts in the west and soft cliffs on the north-east coast. Boulder clay areas can shrink near trees, and historic chalk mines are recorded under parts of Norwich. Only an investigation can say why a particular building has moved.

How do I know if my wall ties have failed?

The clearest sign is horizontal cracking in the mortar joints repeating every few courses, often with a bulge or a lifted roofline. Wire ties can fail with no cracking at all, so a tie survey with a metal detector and borescope is the only reliable check.

Which houses are most at risk of wall tie failure?

Cavity-walled houses built before the 1980s are most at risk, especially those with mild steel ties, black ash mortar or an exposed position. Coastal and hilltop houses, and elevations facing the prevailing weather, tend to fail first.
