Rigid Inclusions Ground Improvement
Geopier® rigid inclusion foundation systems are ground improvement elements used to transfer loads through weak, compressible soils and into deeper competent bearing soils. They are ideal for settlement control of heavy structures underlain by thick deposits of compressible soils (organics, soft clays, and loose sands). They can also be used to limit settlement of highly sensitive structures and prevent settlement-related damage to existing structures and utilities. What sets rigid inclusions apart from deep foundations is that they are not structurally connected to the superstructure, which allows for foundations and slabs to be designed as conventional spread footings and slabs-on-grade.

How Does Geopier Ground/Soil Improvement Work?
Our rigid inclusions are comprised of plain concrete, cement-treated aggregate, or grout/aggregate mixture. Geopier rigid inclusion designs are used to increase bearing capacity (up to 12,000 psf) and minimize total and differential settlements in soft soil profiles, such as peat or organics, soft silt, or soft clay.

How does Geopier compare to the competition?
There are many choices when it comes to aggregate piers, but not all aggregate piers are created equal. Geopier, with its proprietary Rammed Aggregate Pier® solutions, is the gold standard in aggregate pier technology, engineering, and customer focus.
Other Rigid Inclusions
Most competitors offer only one type rigid inclusion, limiting their ability to deliver an optimal solution.
- Typically require a robust load transfer
- Typically lower axial capacity
- Typically only able to resist axial loads
Geopier® Rigid Inclusions
Geopier has several rigid inclusion solutions that are custom designed to meet your project const and schedule needs.
- Only require a 6- to 12-inch-thick granular pad
- Wide range of axial capacity available
- Ability to resist axial, uplift, and lateral loads with various technologies
Deep Foundations
Deep foundations provide excellent settlement control, but at significant cost and schedule impact.
- Expensive pile caps and structural slab design/construction
- Pile cap size driven by number of elements
- Slower installation and delays for foundation construction
Geopier® Rigid Inclusions
Geopier rigid inclusion's match deep foundation capacities and settlement performance, but with simpler design and less cost.
- Shallow spread footings and slabs-on-grade design/construction
- Footings designed for bearing pressures of 5 to 10+ksf
- Rapid installation and foundation construction
