Underpinning is a building method that strengthens foundations by deepening them or spreading weight over a larger area. This technique is often needed due to soil problems or changes in the structure.
Underpinning
Underpinning is often necessary when the existing foundation is inadequate due to factors like:
Soil conditions:
Expansive clay soils, erosion, or soil settlement can compromise foundation stability.
Foundation issues:
Cracks, settlement, or other damage to the foundation can necessitate underpinning.
Changes in building use:
Adding a basement or increasing the load on the foundation may require reinforcement.
Why it's needed: Underpinning helps prevent further structural damage and ensures the safety and longevity of the building. It can address issues like:
Foundation settlement:
When the ground beneath the foundation sinks, causing cracks in walls, floors, or the foundation itself.
Differential settlement:
Different foundation parts settling at different rates lead to uneven floors and other problems.
Weak or unstable soil:
Soil that is too soft or prone to movement can compromise the foundation’s ability to support the building.
