Wall tie replacement is a structural repair performed to ensure the stability and safety of cavity walls in a construction project. However, once the process is complete, you will find visible signs such as drilled holes, disturbed mortar, cracks, or detachment in the render.
Addressing these cosmetic issues is essential not only for visual aesthetics but also for maintaining the property’s long-term value. Hence, professionals after wall tie replacement in Bournemouth provide effective treatments to restore exterior walls.
What is wall tie replacement?
Cavity wall ties are metal components that connect the inner and outer leaves of a cavity wall, ensuring structural stability. Over time, these ties generally corrode and become damaged. This led to potential issues such as horizontal cracking and the development of bulges in the walls.
During wall tie replacement, professionals will drill into the brickwork and install new ties to restore structural integrity.
What happens when the wall ties need to be replaced?
When the walls are covered in bare render or unpainted bricks are visible, it indicates that the walls’ weather-repelling properties are not functioning properly. Wall tie replacement is a rare requirement in new builds. However, it is a common instance in poorly built old properties.
When the weather-repellent properties fail, the surfaces begin to absorb a lot of water. especially if the building is exposed to heavy rain, the wind will force water into the walls, causing long-term issues that hamper structural integrity. This causes rust in the wall ties.
The metal rods that hold the brick and block walls of the property are prone to collapse. That’s when you would need to replace the wall ties.
What are the common post replacement issues?
Visible drill holes: The installation process leaves visible holes on the external walls
Mortar problems: Drilling can disrupt existing mortar joints, leading to improper water ingress.
Render damage: Rendered walls can crack and, in some cases, detach during replacement.
How to restore the home’s exterior after replacement?
Fill drill holes
Professionals generally prefer to fill the drill holes with mortar mix that matches the existing wall finish and colour.
Repointing mortar joints
They will check the disturbed mortar joints and begin repointing immediately. This helps restore aesthetics and prevents water ingress.
Repairing render
If the render on the walls is damaged, the professionals will carry out the repairs effectively. If the damage is extensive, then re-rendering of the entire wall might be required.
Cleaning the wall surface
Once the visible problems are fixed, the professionals apply clean coats of paint. Before that, they remove dust and debris from the walls to ensure smooth paint adhesion and a seamless paint finish.
