Deep foundations are structural elements used to transfer building and infrastructure loads to competent soil or rock layers below the ground surface. These systems are employed when shallow foundations or ground improvement alone cannot safely support design loads or performance requirements.
Keller’s experience in deep foundations
Keller has decades of experience delivering deep foundation solutions for a broad range of project types, soil conditions, and structural demands. Our teams combine advanced drilling and installation expertise with in‑house engineering to deliver foundation systems that meet demanding performance and constructability requirements.
Where appropriate, deep foundations are integrated with Keller’s other geotechnical techniques, including ground improvement, earth retention, grouting, and groundwater control, to deliver coordinated, efficient solutions under a single contract.
Common uses
- Bypass weak, compressible, or unsuitable near-surface soils
- Support heavy, concentrated, or highly variable structural loads
- Control total and differential settlement
- Transfer loads to deeper bearing strata or rock
