SubStruct LLC is a national aggregate pier contractor and deep foundation contractor. We design, install, and verify aggregate piers, rigid inclusions, and helical piers in house—giving your project one accountable partner from bid through verification.
The best foundation solution is the one that fits the soils, structural loads, schedule, and economics of the project—not a one-size-fits-all system.
Our engineering and construction teams work as one. We review the geotechnical information, select and design the right system, install it with purpose-built equipment, and verify performance in the field.
See how we deliverFrom shallow ground improvement to deep foundation support, SubStruct evaluates the whole load path before recommending a system.
Dense, compacted aggregate elements increase composite ground stiffness, reduce settlement, and support conventional shallow foundations.
High-stiffness cementitious elements transfer loads through compressible strata and work with an engineered load-transfer layer to control settlement.
Steel helical elements are advanced with documented torque to provide reliable compression or tension support with minimal vibration and excavation.
SubStruct supports aggregate pier projects across the United States with one in-house team responsible for engineering, field execution, and performance documentation.
Request an aggregate pier reviewOur engineers review the geotechnical report, structural loads, foundation geometry, settlement criteria, access, and schedule before developing the aggregate pier layout and depth. Design submittals include settlement analysis, bearing capacity analysis, construction requirements, and project-specific verification criteria.
In the field, experienced crews predrill where required, place aggregate into the open hole, and compact it in controlled lifts with high-energy tamping equipment. Installation records, aggregate quantities, pier depths, load testing, and as-built documentation connect the installed work back to the design intent.
When the same team designs, installs, and verifies the work, field decisions stay aligned with design intent.
Engineering, installation support, quality documentation, and performance testing stay connected.
Geotechnical data, loads, foundations, access, and schedule.
System selection, layout, settlement analysis, bearing capacity analysis, and sealed submittals.
Specialty crews, purpose-built tooling, and documented production.
Load testing, installation records, and final quality documentation.
Our field verification closes the loop between calculated performance and installed conditions. The result is clear documentation for the project team and faster resolution when the ground varies.
Every project is different. These are the questions our team addresses early when evaluating an aggregate pier solution.
An aggregate pier contractor evaluates the project soils and structural loads, designs the pier system, installs compacted aggregate elements, and documents field performance. SubStruct keeps design, installation, and verification connected in house.
Aggregate piers are commonly evaluated where soft or loose soils could cause excessive settlement and when a project needs a practical alternative to undercut and replace. Suitability depends on the geotechnical conditions, foundation loads, settlement tolerance, access, and schedule.
Yes. SubStruct mobilizes across the United States from offices in Coweta, Mesa, Charleston, Columbus, and Atlanta for commercial, industrial, municipal, education, data center, tank, and infrastructure projects.
Project-specific verification may include modulus load testing, installation logs, pier depth and aggregate quantity records, and final as-built documentation. The verification program stays aligned with the sealed design and project requirements.
A growing national portfolio across commercial, education, municipal, industrial, data centers, tanks, infrastructure, and more.
SubStruct mobilizes nationally from five offices across Oklahoma, Arizona, South Carolina, Ohio, and Georgia.
