1800 18 20 20Open & Uneven Control Joint Repair in Melbourne & Adelaide
Repair Foundation Movement Affecting Brick Articulation Joints Without Major Excavation
Control joints (also known as articulation joints) are intentionally built into brickwork to allow buildings to expand, contract and move slightly with seasonal temperature and moisture changes. However, when these joints become noticeably wider, uneven or misaligned, they may be signalling movement beneath your home's foundations rather than normal building movement.
At Rectify, we specialise in identifying whether open or uneven control joints are performing as intended or whether they indicate foundation settlement, subsidence or soil movement. Using advanced chemical underpinning, polyurethane resin injection and ground stabilisation techniques, we strengthen the supporting ground beneath your property to help prevent ongoing structural movement with minimal excavation and disruption.
Why Are My Control Joints Opening?
Control joints, also known as articulation joints or expansion joints, are designed to accommodate small amounts of normal building movement caused by temperature changes, material expansion, and minor foundation settlement. However, if these joints become noticeably wider, uneven, or continue to open over time, they may indicate movement occurring beneath the building rather than normal structural behaviour.
In many cases, widening control joints are a symptom of foundation movement caused by changing ground conditions. Identifying the underlying cause is essential to determine whether the movement is within expected limits or whether foundation remediation is required. At Rectify, we investigate the source of the movement before recommending the most appropriate solution.
Seasonal Moisture Variation
Seasonal changes in rainfall and temperature can significantly affect the moisture content of the soil beneath a building. During prolonged dry periods, soil may contract, while heavy rainfall can cause it to expand or soften.
These natural cycles of movement can result in repeated foundation movement, causing control joints to gradually widen over time. Monitoring changes in articulation joints between seasons can help identify ongoing structural movement.
Poor Soil Compaction
If the soil or fill material beneath a home was not adequately compacted during construction, it can continue to compress or shift over time, reducing the support available to the footings above.
As the ground gradually consolidates, differential foundation movement can occur, causing articulation joints to widen or become uneven. An engineering assessment can identify whether poorly compacted ground is contributing to the movement.
Underground Water Leaks
Leaking water pipes, damaged stormwater systems, or underground plumbing failures can introduce excess moisture beneath foundations. This may weaken the supporting soil, wash away fine particles, or create underground voids.
As the ground loses strength, differential foundation movement may occur, causing articulation joints to widen and structural cracks to develop. Repairing the source of the leak is an important part of preventing further movement.
Erosion
Erosion occurs when flowing water gradually removes or weakens the soil supporting a building's foundations. Poor drainage, heavy rainfall, groundwater movement, or damaged drainage systems can all contribute to the loss of supporting ground.
As erosion progresses, foundations may settle unevenly, resulting in widening control joints, cracking, and other signs of structural movement. Rectify provides advanced ground improvement and erosion remediation solutions designed to restore support while minimising disruption.
Ageing Foundations
Over time, buildings naturally experience decades of seasonal movement, environmental exposure, and gradual settlement. While many older foundations remain structurally sound, changing soil conditions and ageing infrastructure can make them more susceptible to movement.
When combined with other contributing factors, ageing foundations may result in articulation joints gradually opening beyond their original design tolerance. An engineering assessment can determine whether the movement is historical or ongoing.
Poor Drainage
Poor drainage can allow excessive water to collect around foundations, weakening supporting soils or causing reactive clay to expand. In other situations, inadequate drainage may contribute to erosion or uneven drying of the ground.
Over time, these changing ground conditions can lead to foundation movement, affecting the alignment of doors, windows, walls, and floors. Maintaining effective site drainage is an important part of protecting a property's structural integrity.
When Should You Be Concerned?
While articulation joints are designed to accommodate movement, excessive widening or uneven alignment often indicates that the supporting foundations are moving beyond their intended tolerance.
At Rectify, we begin by identifying the cause of the movement before recommending any repairs. Where foundation instability is identified, advanced solutions such as polyurethane resin injection, chemical underpinning, ground improvement, and foundation stabilisation can improve ground support and help minimise further structural movement. By addressing the source of the problem rather than simply repairing the visible symptoms, we provide long-term solutions for residential, commercial, industrial, and infrastructure assets.
