Structural Repairs & Stabilisation
This category covers contractors who carry out structural repair to historic buildings: stitching cracked masonry, installing lateral restraint and tie bars, repairing bulging and leaning walls, grouting rubble cores, and stabilising arches, vaults and gables. Most of the work follows an engineer's diagnosis, and the best of it is minimal and reversible. Old buildings have usually moved once and stopped; the task is to distinguish historic movement from active movement, address the cause, and then repair with materials compatible with the wall rather than stiffening one part until the next part fails.
What this category covers
- Crack stitching and helical reinforcement in masonry
- Tie bars, pattress plates and lateral restraint
- Repair of bulging, leaning and delaminating walls
- Grouting of rubble-filled and voided wall cores
- Temporary propping, needling and arch stabilisation

Getting structural repair right on an old building
Diagnose before you repair. Cracking is a symptom, and stitching it without establishing whether movement is active, and what caused it, simply hides the problem. Monitoring over a season, drains and gutter checks, and trial pits are cheaper than the wrong repair.
Match the repair to the wall. Cement mortars and rigid modern fixings concentrate stress in soft historic masonry and can cause fresh cracking alongside the repair. Lime-based grouts and mortars, and fixings sized to the wall, allow the structure to keep behaving as it always has.
Prefer visible and reversible. Tie bars with pattress plates have kept buildings standing for two centuries and can be inspected, adjusted and removed. Hidden resin and helical systems are useful, but they cannot be inspected later and are difficult to undo.
Expect consent and, often, a structural engineer's report. Listed Building Consent is normally required, and the local authority will usually want the diagnosis, the monitoring evidence and the proposed repair set out together rather than the repair alone.
Questions to ask
Is a crack in an old wall always a problem?
No. Most historic buildings carry old cracks from movement that stopped long ago. What matters is whether movement is current, which is established by monitoring over time rather than by a single inspection, and whether water is entering through the crack.
Are helical bars suitable for historic masonry?
They can be, in the right situation, but they are concealed, effectively permanent and stiffen a section of wall relative to its surroundings. An engineer should confirm that stiffening that area will not simply move the problem elsewhere.
What causes bulging in a rubble-filled wall?
Typically the loss of bond between the outer face and the core, often after long-term water ingress washes out fine material. Repair usually combines drying the wall, grouting the core with a lime-based grout, and reinstating through stones or ties.
