Crack stitching in Abergavenny

How we usually approach crack stitching
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 happens during crack stitching, step by step?
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.
Repoint to match
The cut joints and crack are pointed in a mortar chosen to match the colour, texture and strength of the existing work. On older houses with soft bricks, a lime mortar is used so the repair does not trap moisture.

Rules for crack stitching in Wales

Questions about crack stitching in Abergavenny
What is the price of crack stitching in Abergavenny?
Guide prices for crack stitching in Abergavenny 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 carry out crack stitching in Abergavenny?
We do. Abergavenny and the surrounding area are covered, including nearby Abertillery and Pontypool. A free initial assessment from your photos is the first step.
Does the ground around Abergavenny cause cracking?
The valleys of Blaenau Gwent, Torfaen and Islwyn lie on the South Wales coalfield with extensive historic workings and spoil tips, while Newport and Monmouthshire have Mercia Mudstone, alluvium and Old Red Sandstone. Only an investigation can say why a particular building has moved.
Does crack stitching stop a wall moving?
No, crack stitching reconnects cracked masonry but does not stop the movement that caused it. If the ground is still shrinking, a drain is still leaking or ties are still rusting, a stitched wall can crack again nearby. The cause has to be identified and dealt with first.
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.
