Armorpact Reinforced Aggregate Column Installation in California.
Reinforced aggregate pier columns engineered for heavier loads and challenging soil profiles where standard piers fall short.
Armorpact is a reinforced aggregate pier system designed for heavier load applications and more challenging soil profiles than standard Geopier piers can address on their own. A structural reinforcement element is integrated into the aggregate column, significantly increasing both vertical and lateral capacity.
The result is a high-capacity intermediate foundation element that bridges the gap between conventional Geopier systems and deep foundations. Armorpact is specified when a site demands more than the standard GP3 or Impact pier can provide, but where a full pile program would be unnecessarily expensive or schedule-intensive.
Common applications include heavy industrial facilities, large tank foundations, transportation infrastructure, and embankment support over soft soils. Armorpact preserves the design-build, schedule, and cost advantages of the Geopier approach while expanding the envelope of soils and loads it can serve.
WGI delivers Armorpact installations under the same rigorous quality control program as every other Geopier system, with modulus testing, as-built documentation, and direct collaboration with the geotechnical engineer of record.
Frequently Asked Questions
Have a different question about your site or project? Reach out and our team will respond.
Armorpact is specified when load demands exceed what a standard aggregate pier can carry, or when the soil profile is weak or variable enough that the added reinforcement is needed to meet the project's capacity and settlement targets. WGI reviews the geotechnical report and structural loads to determine the right system.
Armorpact substantially increases the capacity of an aggregate pier element. The exact capacity depends on column geometry, soil profile, and the reinforcement configuration, but Armorpact extends the Geopier load range well into the territory commonly served by light-to-moderate deep foundation systems.
Armorpact takes slightly longer to install per element than an unreinforced pier because of the reinforcement installation step. However, on suitable projects it is still much faster and less expensive than a comparable driven pile or drilled shaft solution.
