WHAT IS UNDERPINNING?
Underpinning refers to the process of strengthening and stabilizing the foundations of a property. The most common scenario for underpinning is when a house is suffering from subsidence and needs to be supported with deeper footings. There are then a number of underpinning methods, but it will almost always involve digging beneath the existing footings to make them deeper and/or wider. Read more about underpinning methods here.
WHY IS UNDERPINNING NEEDED?
There are several reasons why underpinning might be required. As we mentioned earlier, the most common reason is that soil subsidence has caused foundations to sink. However, we also come across the following fairly frequently:
- The original foundation was faulty (i.e. not strong enough or the wooden piles have decayed).
- Nearby excavation has caused the foundation to weaken.
- Additions to the building such as a second storey necessitate the strengthening of foundations.
- Floods, earthquakes or other natural disasters have weakened or moved the foundations.
