Reasons Why it is Important to Match the Expansion Joint of a Rendered Wall to the Structure
When it comes to rendering a wall, one of the most important elements to consider is the expansion joint. Expansion joints are designed to allow for movement in the render and to prevent cracking or other damage occurring as a result. When these joints are not properly matched to the structure of the building, it can cause all sorts of problems down the track. Here are some reasons why it is so important that you get this element right during your render job.
Expansion Joints Help Prevent Cracking
One of the main issues that can arise from failing to correctly install an expansion joint when rendering a wall is cracking. All walls will move slightly over time due to changes in temperature and humidity, and if there isn’t enough space for this movement, the render will become stressed and eventually crack. With an expansion joint correctly matched to the structure of the wall, this movement can be absorbed without causing any damage.
Expansion Joints Help Maintain a Neat Appearance
Another important consideration when rendering a wall is that it should look neat and uniform once completed. By using an expansion joint that is properly matched to the structural elements of the building, you can ensure that this is possible even after time has passed and the wall has moved slightly. This helps maintain its aesthetic appeal in both the short and long term.
Expansion Joints Help Prevent Long-Term Damage
When an expansion joint isn’t correctly installed on a rendered wall, it can lead to some serious long-term damage. If the wall is allowed to move without any space for this movement, it can cause the whole structure of the building to shift and become unstable – something that obviously needs to be avoided at all costs. By correctly matching the expansion joint of a rendered wall to its structure, you can ensure that no such problems will occur.
Expansion Joints Help Maintain Waterproofing Integrity
When rendering a wall with an expansion joint, it’s also important to consider waterproofing elements. Without properly matched expansion joints, water can penetrate into cracks in the render which can lead to serious issues such as dampness and even mould growth over time. With a correctly installed expansion joint, this problem is completely eliminated as water is kept out of the render and can’t cause any damage.
Expansion Joints Help Maximise Durability
Finally, correctly matching an expansion joint to the structure of a rendered wall is key to ensuring its long-term durability. Without this, the wall will be more prone to cracking or other issues over time as it moves and shifts due to changes in temperature and humidity. By using an expansion joint that is properly matched to the structure, you can ensure that your render job will last for many years without any major problems.
In conclusion, it’s clear that correctly matching an expansion joint of a rendered wall to its structural elements is absolutely essential if you want a successful job. Not only does it help prevent cracking and maintain a neat appearance, but it also prevents long-term damage and maximises the durability of the render. So make sure you don’t overlook this vital element when you are rendering your next wall!
