Underpinning and Foundation Repair

Close up of a newly renovated home.

Underpinning is a construction technique used to strengthen and stabilise an existing building’s foundation. It involves excavating the soil beneath the foundation and replacing it with a stronger material, such as concrete. This technique is commonly used when the original foundation is not strong enough to support the weight of the building or when the soil underneath has become unstable due to disturbance, settlement, or erosion.
