Subsidence Underpinning


Should structural defects be found, and a property requires underpinning to strengthen the foundations BH Basements are established experts in our field. Our operatives are trained both in house and externally to ensure their skill set is of the highest standard and is maintained so by external auditors.


What is Subsidence Underpinning?

Subsidence underpinning is a construction technique used to stabilize structures that have been affected by subsidence. Subsidence refers to the gradual sinking or settling of the ground, which can lead to uneven or unstable foundations for buildings. Subsidence can be caused by various factors, including soil erosion, groundwater movement, mining activities, or natural geological processes.


Strengthening and Reinforcing

When subsidence affects a building, it can result in structural damage, such as cracks in walls or floors, uneven floors, or doors and windows that no longer close properly. Subsidence underpinning involves strengthening or reinforcing the foundation of the affected structure to prevent further movement and stabilize the building.


Stable Foundations

Underpinning typically involves excavating sections of the existing foundation and then filling those excavated areas with concrete or other structural materials to provide additional support. This effectively transfers the weight of the building to deeper, more stable soil layers, bypassing the weakened or subsided sections of the foundation.

“Really enjoyed working with BH Basements on our Project. Tom and Chris were very helpful, experienced and proactive. It was a tight difficult build with occupied neighboring properties but they managed to complete the works with great success. Would be very happy to work with again!”
