Crack Stitching in Melbourne

Crack stitching is a structural reinforcement technique used to repair cracked brick walls without the need for demolition and rebuild. It involves cutting slots into mortar joints across the crack line, inserting stainless steel helical reinforcing bars, and grouting them in place. Done correctly, it restores the structural continuity of the wall while leaving the brick face largely intact.

When Crack Stitching Is Appropriate

Crack stitching suits cracks caused by thermal movement, minor subsidence, or differential settlement where the underlying movement has stabilised. It is not a fix for actively moving walls caused by ongoing ground movement or unresolved structural issues — in those cases, an engineer's assessment is needed first.

• Step cracks in mortar joints
• Vertical cracks through bricks and mortar
• Cracks at window and door openings
• Diagonal cracks from differential settlement
• Heritage walls where traditional repair must be maintained

Process

1. Inspect and assess the crack — confirm movement has stabilised
2. Cut slots into mortar beds across the crack line
3. Clean and prepare slots
4. Install stainless steel helical bars
5. Fill slots with specialist structural grout
6. Repoint to match existing mortar
