Deepening, stiffening and rescuing foundations under structures that are staying put.

Underpinning transfers the load of an existing structure onto deeper or stronger ground - because the original foundations are failing, because the ground beneath them has changed, or because a new basement or neighbouring excavation is about to remove their support. Techniques run from traditional mass-concrete pins dug a metre at a time to beam-and-pile schemes, mini-piled underpinning, jet grouting and resin injection.

About Underpinning & Foundation Strengthening

The defining constraint is that the structure stays up, occupied and within movement tolerances while its support is cut away and rebuilt in sequence. Monitoring is not an add-on: trigger levels, hold points and a rehearsed response to unexpected movement are the difference between underpinning and undermining.
