Underpinning
Underpinning is a specialist technique used to strengthen or stabilise the foundations of an existing building. It involves working beneath the structure to extend the depth of the existing footing or transfer its load onto firmer ground below. This restores stability without the need to demolish or rebuild.
At Capital Piling, we deliver underpinning on projects of all sizes, from single residential properties through to commercial and multi unit schemes. Every project is carefully planned to suit the specific ground conditions, structural requirements and overall scope of works.

Sites with variable or challenging ground conditions
Is Underpinning right for your
project?
Underpinning is often associated with subsidence repairs. That said, it is equally suitable ahead of planned construction works where a basement, extension, or additional storey increases demand on the existing foundation.
The most appropriate method depends on multiple factors. Our team will review your project requirements and advise on the most suitable stabilisation solution before any commitment is made.
What is Underpinning?
Underpinning is a foundation technique that strengthens an existing structure by extending support to a deeper or more stable layer of ground. It's a solution to ground movement, structural change, or nearby works that present a risk. Piles are installed using specialist piling rigs. This allows for precise control over depth, reinforcement, and installation quality.
The flexibility of underpinning means it can be engineered to suit a wide range of structures and loading requirements. This makes it suitable for both reactive subsidence repairs and proactive stabilisation works.
