Caisson
Caisson Foundation Repair | Deep Foundation Support
When a foundation is settling due to unstable, weak, or shifting soil at shallow depths, caissons offer a deep, load-bearing solution that transfers the weight of the structure to competent soil or bedrock far below the surface. Keystone Foundation Repair has the experience and equipment to design and install caisson systems for both residential and commercial properties across our service area.
Your foundation is only as strong as what it’s sitting on; if the soil beneath is failing, it’s time to go deeper.
What Are Caissons and How Do They Support a Failing Foundation?
Caissons, also called drilled piers, are large-diameter, deep concrete cylinders installed by drilling into the ground alongside or beneath a failing foundation. Once drilled to the required depth, which may range from 10 to 30+ feet depending on soil conditions, the hole is filled with reinforced concrete, creating a massive column of structural support that bypasses weak upper soils entirely.
Think of a caisson as a new foundation beneath your foundation, built on ground that won’t move. Find out if this is the solution your home needs.

The foundation is then connected to or supported by these caissons, halting settlement and restoring load transfer to stable ground. Caissons are particularly effective in areas with significant fill soils, organic layers, or expansive clays. Unlike helical piles or push piers, caissons are better suited for locations where large bearing capacity is needed or where other pile systems encounter obstructions.
When Are Caissons the Right Choice for Foundation Repair?
Caissons are a robust, engineered solution typically recommended when:
- Settlement is caused by deep layers of unstable or fill soil
- Other pile systems are not suitable due to soil conditions or obstructions
- Heavy structural loads require a large-diameter bearing element
- Commercial or multi-story residential properties require engineered deep foundation support
- A structural engineer has specified caissons as part of a comprehensive repair plan
See your situation on that list? Don’t sit on it, deep foundation problems don’t get cheaper with time. Let’s talk.
Keystone Foundation Repair works closely with structural engineers and follows all applicable building codes when installing caisson systems. We handle the entire process, from soil evaluation to installation to final documentation, ensuring your repair is done right and properly recorded.
