We Engineer and Install Cost-Saving, High-Capacity Steel Foundations for Buildings, Industrial Structures, & Retaining Walls
Wherever you would use deep foundations, piles, pile alternatives, or large concrete pours, consider Structural Foundations first. Structural Foundations is a geotechnical and structural consulting engineering firm and licensed general contractor. We engineer and hydraulically install high-capacity steel foundations for buildings, industrial structures, retaining walls, and other large applications, saving up to 50% in cost and valuable time.
Save 25% to 50% over deep foundations and large concrete pours
Most foundations install in mere minutes to an hour each
Individual foundation capacities of 20 to 600+ kips bearing and uplift
Overturning moment capacities exceeding 1,000 ft.-kips
Over 800 installations across the United States
Over 30 years of field performance
Bearing capacity is calculated by the hydraulic pump's pressure gauge reading and cylinder area.
Individual Structural Foundations have achieved the following impressive capacities:
600+ kips bearing capacity in moderate-strength soils
600+ kips uplift resistance capacity in moderate-strength soils
300+ kips bearing capacity in very poor soils
300+ kips uplift resistance capacity in very poor soils
1,000+ ft.-kips overturning moment capacity in poor soils
"The foundation strength is proven during the installation process, as the hydraulically applied installing load is the same as the uplift and bearing capacities.
"Another unique feature of the foundation is the ability to increase the natural bearing capacity of the soil."
- U.S. Department of Energy, NREL, Cooperative Research and Development Agreement, 2004
Our hydraulic method of installation provides an accurately applied and known force to the foundation and soils within the zone of influence. Foundation bearing and uplift capacity is verified during the installation process, with settling and creep virtually eliminated at equal or less loading than the installation force. A Structural Foundation is a tested foundation!
Towers & Columns
Just weld or bolt your structure to, or pour concrete over, the installed foundation!
Small-diameter hole drilled.
Anchor inserted, hydraulically actuated, and soils pre-stressed.
Steel foundation hydraulically installed using anchor rod.
Anchor removed (or kept in place for high-uplift applications). Hydraulics removed. Voids filled with the excavated material. Steel foundation secure and ready to be built upon.
Installation Features & Benefits
After drilling, most foundations require only mere minutes up to an hour.
Equipment with a drilling attachment or a small drilling rig + Front-end loader or small crane to lift foundations + Compact hydraulic system.
None! Spoils from drilling are minimal and most can be returned to the pipe of the foundation or easily and thinly spread in the vicinity.
None from foundation installation! Minimal vibration from drilling.
