Underpinning is the process of strengthening the foundation of an existing structure. The Traditional method strengthens an existing structure's foundation by digging boxes/panels by hand or using small equipment, and sequentially pouring concrete into each box/panel. The result is a new foundation built underneath the existing foundation. This underpinning method is generally applied when the existing foundation is at a shallow depth.
We have been installing underpinning since we went into business in 1979. Pro Caissons’ experience can help the customer with the design and installation of underpinning.
