Underpinning and Piering

Underpinning is the process of modifying an existing foundation system by extending it to or into subsurface strata that is deeper and more stable than the near surface soil that sup- ports the existing foundation system. This is done to provide vertical support that is not present in the existing design. Methods of underpinning include the construction of footings, stem walls, driven piling or drilled piers.

CrackerJack has over 25 years experience in underpinning and restoring buildings which have suffered structural damage due to destabilisation of footings and foundations.

We can provide you with a free quotation for any underpinning work required.
