Intermediate foundation systems to strengthen ground and reduce settlement
D.W. Kozera, Inc. delivers geotechnical design support, field observation, and testing services for Rammed Aggregate Piers® (RAPs) and Compacted Aggregate Piers (CAPs) ground improvement solutions that increase stiffness and load-bearing capacity in soft or variable soils. These systems are a practical alternative to deep foundations for slabs, spread footings, embankments, and light to moderate structures.
Our team develops site-specific pier design recommendations and works alongside specialty contractors during installation to help maintain consistency and performance. We also provide observation and testing during modulus test setups, construction, and production pier installation, giving design teams, owners, and contractors confidence in both the system design and field execution.
Services Offered
- Subsurface Evaluation to Assess RAP or CAP Suitability
- Field Observation of Installation to Support Consistency and Quality
- On-Site Support During Modulus Test Setup and Execution
- Construction Testing and Reporting to Document Pier Behavior
- Coordination with Structural and Specialty Installation Teams
- Documentation for Engineer of Record, Permitting, and Design Review
