Homes that are built on reactive clay fill or other unstable soils move far more than if your home were built on a sand base.
This can lead to cracking in brick walls and movement in the foundations.
90% of all brick homes feature strip concrete foundations on outer walls (and some interior walls). Sometimes these footings can subside or crack, causing damage to the structure of the property. Underpinning refers to a process whereby new concrete pads are inserted under the existing strip concrete foundations, providing additional support and bringing the house back to its original levels.
Installing soil moisture probes to fully assess the conditions of your soils can help to prevent movement due to moisture damage.
