How To Repair Cracks In Brick Walls?
Brick walls are known for their durability and strength, but over time, they can develop cracks or masonry cracks that can compromise their structural integrity and lead to further damage if left untreated. It is essential to address these issues to prevent them from becoming bigger problems.
In this guide, we will discuss brick wall crack repair methods, including the stitching method, to fix cracked masonry and other types of structural problems. Whether you’re a homeowner or a professional contractor, this article will provide you with the information you need to repair cracks in brick walls effectively.
Definition & overview of brick wall cracking
Brick wall cracking occurs when the bricks and mortar joints that hold them together start to deteriorate. This can happen due to various reasons, such as soil subsidence, temperature fluctuations, water damage, tree roots, or poor construction works. Cracks in brick walls can be cosmetic or structural, and it is crucial to identify the cause and type of crack before attempting any repair work.
Identifying the causes of cracks in brick walls
To repair cracks in brick walls, it is essential to first identify the underlying issue that caused them. The type of crack can indicate the cause, such as horizontal cracks indicating foundation movement or vertical cracks pointing to moisture absorption. A professional brick wall crack repair expert can help inspect the wall to identify the cause and suggest the best repair method.
Preparing the wall for repair
Before repairing the cracks, it is necessary to prepare the wall by removing any loose material, debris, or excess mortar. A stiff bristle brush or wire brush can be used for this purpose. The cracks should be cleaned and dried thoroughly, and any loose mortar or broken bricks should be removed.
Filling cracks with a cement mixture
Once the wall is prepared, the cracks can be filled with a cement mixture. The type of repair material used will depend on the type of crack and its severity. For minor cracks, a mixture of cement and water can be used to fill the crack. Epoxy mortar or other non-shrink grout can provide a more permanent solution for larger cracks.
- What materials are needed?
The materials required for repairing brick wall cracks include cement, water, a trowel, a mortar chisel, a finger trowel, a diamond blade, stainless steel or brick stitching bars, and waterproof gloves.
- How to mix the cement mixture?
To mix the cement mixture, first, add small batches of mortar to clean water and mix thoroughly until the mixture has the consistency of toothpaste. Then, using a trowel or finger trowel, apply the mixture to the crack, ensuring it fills the entire depth of the slot. If using an epoxy mortar, follow the manufacturer’s instructions carefully.
Painting a seal over the repaired area
After the cement mixture has dried, it is recommended to paint a seal over the repaired area. This will protect the repaired area from water penetration, further damage, and moisture uptake. A bead of grout or permacem grout can be used to seal the repaired area.
Checklist for long-term maintenance and repair
To ensure the longevity of the repaired brick wall, it is essential to perform regular maintenance and repair. This includes checking for any cracks in the wall structure, especially around windows, doors, and foundation walls. Additionally, walls with control joints, expansion joints, or tie failure should be monitored for any signs of structural damage. Professional brick tuckpointing and crack stitching are highly recommendable to avoid structural failures.
In conclusion, repairing cracks in brick walls is an important step in maintaining the structural integrity of your building. From small hairline cracks in a new wall to more extensive masonry damage, there are several methods you can use to fix the problem.
Depending on the severity of the damage, you may need to call in a professional contractor to help with the repair work. By following the guidelines outlined in this article, you can learn how to repair cracks in brick walls and keep your property in excellent condition for years to come.
