Foundations are quite possibly the most important structural element of a building so it is important that they are constructed well and built to last the lifespan of the building. However, changes in ground conditions do not guarantee that this will always be the case. The formation of sinkholes and other unexpected geological hazards may increase the probability of damage to the foundations of your home so it is a good idea to have your building inspected when you notice early alarms and signs of concern.
If you are reading this it is quite possibly because you have noticed some cracks in your brick walls. You might have noticed these cracks appear randomly or maybe they have come to your attention through a building inspection. Unfortunately you are not alone as cracks in walls are very common in Sydney, especially in areas with very reactive foundation soils. But with the correct procedures, defective walls can be repaired without the need for replacing them as long as you take the right actions before it is too late.
