GeoConcrete Column Deep Foundation Improvement in California.
A deep ground improvement system that uses cementitious grout columns to support the highest load demands.
GeoConcrete Columns are a deep ground improvement system that uses high-strength cementitious grout or concrete to create rigid inclusions within weak or compressible soils. The columns are installed by drilling to design depth and pumping grout under controlled conditions, producing high-capacity elements that approach the performance of structural piles.
The system is engineered for projects where load demands, soil compressibility, or settlement constraints rule out aggregate pier systems alone. GeoConcrete Columns are routinely installed to depths well beyond what is practical for conventional Geopier elements, opening up sites with thick layers of soft or compressible material.
Typical projects include multi-story buildings, bridge abutments, heavy industrial structures, tall warehouses with high rack loads, and infrastructure crossings where settlement tolerances are tight. The system is also a strong option as an alternative to micropiles when production rates and cost are the priority.
WGI coordinates the GeoConcrete Column program directly with the project's geotechnical and structural teams, providing column design, capacity verification, and as-built records.
Frequently Asked Questions
Have a different question about your site or project? Reach out and our team will respond.
Aggregate piers are made of densely compacted crushed stone. GeoConcrete Columns are made of cementitious grout or concrete. The cementitious material gives GeoConcrete Columns much higher capacity per element and the ability to extend to greater depths, at the trade-off of a more involved installation process.
GeoConcrete Columns are routinely installed to depths well beyond conventional aggregate pier systems. The achievable depth depends on rig configuration and site conditions, but the system regularly reaches the depths needed to bypass thick layers of soft or compressible soils on California and Southwest projects.
Multi-story buildings, bridge abutments, heavy industrial structures, tall warehouses with concentrated rack loads, and tank facilities with strict settlement criteria. Any project where the load demand exceeds what aggregate pier systems can deliver is a candidate.
