What causes cracks in your walls?
There are a number of reasons why a cracked wall occurs. A major cause of cracks in house walls is the ground beneath the foundations. This ground is in a constant state of change. It is important to understand and fix the underlying cause for permanent wall crack repair. Our resin injection method stabilises the ground beneath your foundations increasing the load bearing capacity and prevents further movement of your structure.
Most often the root cause behind wall and ceiling cracks is the soil type beneath a foundation which can cause stress through a foundation and affect the structure above it.
- Granular or sandy organic soil: there will be some degree of erosion as the sand particles can be washed out through malfunctioning plumbing services.
- Reactive clay soil: these will swell with increased moisture content and shrink as it dries, forming “voids” or empty spaces that could lead to washouts. Such soils can reach saturation, turning into something of a “bog” with little to no load bearing.
- Vegetation: sometimes even nearby vegetation can leech moisture from the soils around your property.
Storm water services, sewers, faulty plumbing or even just a dripping tap can affect the stability of your home’s foundation. If the soil beneath your foundation is prone to erosion, voids or bog formation and if your plumbing is not serviceable, this can result in an unstable foundation and cracked walls.
Poor build design and quality can lead to cracked walls. If the building is not adequately constructed with an appropriate drainage system or the ground has not been properly compacted the foundations could be compromised causing instability and cracks in your walls.
