🛠️ How to Stop Wall Movement Permanently
• Assess the Wall Condition
Look for signs of gable end wall movement, such as internal cracks.
Determine if it’s surface-level damage or signs of structural stress.
• Take Advantage of Access
If scaffolding is already in place (e.g., for chimney work), it’s the perfect time to reinforce nearby walls.
• Install Helical Ties
Helical ties run horizontally across the wall, helping to stabilize any bulging or movement.
Drill them evenly along the length of the wall for distributed support.
• Add Restraining Straps
Modern building regs often require these at certain wall positions to resist wind loads.
Wind rushing through alleyways can create suction, risking brickwork blowouts on gable ends.
• Strategically Remove Bricks
Remove selected bricks externally to allow strap access through the cavity.
Drill through to run the straps at an angle, crossing joists internally.
• Notch and Brace Joists
Notch joists approximately 8mm to accommodate the thickness of restraining straps and screws.
Add solid blocking (bracing) between each joist to improve structural coherence.
• Exceed the Minimums
The video shows that adding more straps than required improves long-term resilience.
Consider adding extra straps in the loft area to reinforce the roof triangle.
• Final Step: Repair Internal Cracks
Once reinforced, fill in internal cracks, knowing movement is now controlled.
The wall should remain stable for decades—possibly a century.
This “belt and braces” approach ensures structural integrity beyond standard expectations.
