Repair options we may recommend
Helical bars in cementitious grout
The most common approach. A slot is cut along the bed joint with a twin-blade cutter, flushed out and part filled with a cement-based grout. The helical bar is pushed in, more grout is packed over it, and the joint is pointed to match. The grout cures over a few days.
Best for: Most brick and block walls, including older softer bricks
Helical bars in resin grout
A resin grout bonds quickly and strongly to the bar and masonry and suits wet conditions or work that must take load sooner. It is less forgiving of soft or crumbly bricks, so the choice of grout is made wall by wall rather than as a rule.
Best for: Dense bricks, damp walls and repairs needing a fast cure
What to expect when we carry out crack stitching
Set out the bars
Bar positions are marked across the crack, typically every few courses up its full height, with each bar extending well into sound brickwork on both sides. An engineer’s specification, where there is one, sets the exact spacing and length.
Cut, clean and grout
Slots are cut into the bed joints to the right depth, dust is blown and washed out, and grout is placed. The bars are pressed home and covered, and the crack line is filled or injected.
Make good and record
Internal plaster cracks are cut out and filled where included, and dust is cleared. You receive a short note of where the bars went, which is useful for future buyers, surveyors and any insurance file.

Rules for crack stitching in Wales

Your crack stitching questions
How much will crack stitching cost in Wrexham?
Guide prices for crack stitching in Wrexham start from about £75 per metre of crack, including VAT, on Wales rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you cover Wrexham?
Yes, Wrexham is covered, along with postcode districts LL11, LL12, LL13. We also cover nearby Buckley and Mold.
Is the ground in Clwyd prone to subsidence?
The North Wales coalfield runs beneath parts of Wrexham and Flintshire, where historic workings are recorded, while the coast and vale have glacial clays and the hills are older hard rock. Only an investigation can say why a particular building has moved.
Will crack stitching be visible afterwards?
Usually only slightly, because the bars sit inside the mortar joints and are pointed over. The main giveaway is the colour of new mortar, which can take a few months to weather. Careful mortar matching keeps the line discreet, especially on older brickwork.
How far apart are helical bars placed?
Helical bars are usually placed every few courses up the full height of the crack, each one running well past the crack into sound brickwork. Spacing and bar length depend on the wall and the crack width, and where an engineer has specified the repair, their drawing sets them.
