This article explores steps you can take when you think you may have foundation movement that has led to issues in your walls and ceilings.
Have the foundation assessed
You should start by having your foundation evaluated. You’ll need to know how extensive the movement was, which can also be indicated by the severity of the wall damage. The greater the damage, the more movement has occurred, and the greater the need for foundation repairs.
If your home is on stumps, you’ll likely need to go through the re-levelling process. Over time, your foundation may have become unlevelled due to several reasons. Natural wear and tear can take its toll, while soil reactivity can cause structural movement. Additionally, too much moisture can lead to rot if your stumps are timber. This results in the stumps sinking, moving or settling.
With the re-levelling process, your home’s foundation will be lifted with hydraulic jacks so that the stumps can be repositioned where they need to be to provide the correct support for the structure. The purpose of this process is to adjust the home’s level, leading to even distribution of weight amongst the stumps. Some houses are built on adjustable stumps, which means a quicker, less expensive re levelling process than if the stumps are traditional timber or concrete.
The re-levelling process is a bit different when you have a concrete slab foundation. The surrounds of the house will be dug up to access the slab and the concrete pilings underneath the slab, then using a hydraulic jack, the pilings are pushed further into the soil and new ones placed on top, this process is repeated until the jack cannot push the piling any further below the earth. Alternatively, depending on the severity and the company you hire to do this job, they may access the foundation through floor jacking, small holes are drilled into the concrete where it is sinking. Then, a special releveling polymer is injected through the holes to stabilise the soil beneath the slab. As the soil becomes stabilised, the concrete is re-levelled.
There may be cases where the cost to repair the foundation is beyond what the homeowner is able to afford, this leaves the option to not address the problem. By making an informed decision after having their foundation assessed, a homeowner is choosing to invest in the aesthetic repairs of a place, knowing that the problem will likely reoccur and that the cause is not being addressed and may get worse. Some situations where this is the case could be if someone is renting their home out, with plans to do major renovations or demolition in the future, therefore simply addressing the cracks is what is required to make the property rentable.
Some properties require drainage to be fixed to address shifting foundations, this could be as simple as addressing gutter problems or changing the slope of the soil near the foundations of the house, because water causes movement in soil therefore swelling or contracting in the soil beneath the slab or stumps leading to movement. By addressing drainage, the escalation of the problem can be significantly reduced.
Hire a plasterer to repair the wall damage
