Brick & Render Repairs Perth
What is cement render?
Cement render is a mixture of lime, sand and cement that is applied to the exterior of a brick, cement, stone or concrete building and/or structure to give it a smooth surface. This is a popular and cost-effective method to cover old brick or unsightly concrete block on a structure resulting in an improved appearance, durability and resistance to weather.
What are the advantages of cement render?
Cement render consists of 3 simple ingredients which allow it to be cost-effective and is easy to apply.
What causes cracks in brickwork and render?
Cracks in brickwork and render can occur for a number of reasons with the most common being foundation movement, excessive noise and vibration, heat, damp and water damage. The appearance of fissures and cracks are common on a façade and while the fissures normally occur in the surface, cracks of more than 2mm in width may penetrate the substrate and the masonry. If the wall behind the render surface moves or cracks, then so will the render that’s covering it. The appearance of cracks indicate that a repair is required and if left untreated, the cracks will become larger and the brick structure compromised.

Consequences of not doing brick and render repairs
The common causes of damage to brick and render are:
Bulging or bowed brick
Is usually caused by either rusted wall ties, rusted arch bars or low cement content in the mortar mix which allows a build-up of excess moisture over a period of time.
This is the wearing away of the brick caused by the action of salt migration through the brick. Water, containing dissolved salt, migrates through the brickwork to its surface and as it dries the salt is left behind forming salt crystals which grow in the voids within the brick.
Brick Spalling (crumbling):
Occurs when the moisture inside a brick expands and contracts due to temperature changes, this causes the brick to lose its topmost layer resulting in stress build-up inside the brick because the mortar doesn’t allow the moisture to escape to the brick’s surface where it can evaporate.
Low Quality Materials
In older structures the brick and mortar quality, combined with pressure and time, contribute to the deterioration of the brick.
Normal Wear and Tear
Hairline cracks may appear in render due to normal wear and tear.
This occurs when a brick structure has been cleaned or treated with an abrasive cleaning technique such as high pressure washing which removes the harder crust on the outside of the brick.
What are some of the most common brick repair methods?
Is a common repair method when structural or water damage has occurred. The bricks and mortar joints break down and the structure’s integrity requires restoration. This process involves the grinding and chiselling out of the mortar, cleaning the joint and mix and applying the new mortar.
Is a non-destructive and concealed repair procedure that enables the repair and strengthens the existing masonry. This is a seamless resolution for cracked walls, unstable footings and structural instability which reduces the actual costs for any project.
Is a repair method that not only stops the destructive process but provides benefits as well. This repair involves using two contrasting mortar colours in the mortar joints of the brickwork, with one colour matching the brick so as to provide an artificial impression that the joints are finer than they actually are.
