Foundation Repair & Underpinning provides additional support to foundations that are unable to safely support existing or planned loads. Hayward Baker’s experience and fleet of low headroom, tight access rigs results in the quickest and least disruptive solution.
- Improve weak underlying soils
- Underpin with deep foundation elements
- Raise settled foundations or slabs
- Stabilize sinkhole conditions
- Treat expansive or collapsible soils
Foundations can experience settlement from compressible underlying soils or lateral movements from adjacent excavations, requiring various foundation rehabilitation approaches to stop or correct the movement. As foundation specialists, we have experience with the full range of rehabilitation techniques to provide effective foundation rehabilitation.
A foundation might be underlain by compressible soils or debris that consolidate or decompose over time. Competent soils may be weakened as they ravel into compromised underground utilities underlying a foundation. In karstic regions, sinkholes can cause a building to settle as the soils ravel into a void in the underlying bedrock. Stabilizing the underlying soil can often provide the required foundation support.
Foundation underpinning is an option to treating the soil. Foundation underpinning techniques bypass the problem soils by installing structural elements to transfer the building’s load to underlying competent soils or bedrock. Both underpinning and grouting techniques can be used to raise settled structures. Underpinning foundations can be designed such that the completed solution is below-grade and the aesthetics of the structure are not compromised.
