Solar Farm Piles Alabama

Solar Farm Piles Alabama by Foundation Masters, LLC delivers engineer-led foundations statewide. With 25+ years in civil/structural engineering and 50,000+ piles installed across the Southeast, we provide soil investigations, PE-sealed design, pile installation, and verified testing. Recent utility-scale work includes 500 solar piles installed in Ocala, FL in under two weeks with full QA/QC.
Solar Farm Piles Alabama — Engineering & Pile Testing
We are an engineering-first contractor offering full technical delivery for developers and EPCs:
- Soil investigations per ASTM D1586 (SPT).
- Pile load testing per ASTM D1143 (compression), ASTM D3689 (tension), and ASTM D4945 (dynamic PDA).
- PE-stamped foundation design aligned with ALDOT structures guidance and AASHTO LRFD.
- Wind design per ASCE 7-22 and permitting documentation to local code requirements.
Solar Foundation Systems We Install in Alabama

We select the system around stratigraphy, corrosion exposure, uplift/lateral demand, and constructability:
- Pipe piles (ASTM A252 Grade 3, ~50 ksi yield) for high capacity and bending resistance.
- H-beam / I-beam piles (ASTM A992) for tracker rows and lateral stiffness.
- Helical piers (ICC-ES AC358) for sands/organics and torque-verified installations.
- Concrete piers (ALDOT Class AA ~4,000–5,000 psi) for permanent heavy-duty support.
- Sheet piles (ASTM A572 Grade 50) for slope/erosion control and site stabilization.
Steel protection per ASTM A123 (hot-dip galvanizing) and coatings are specified as needed to achieve a 25–30 year service life, consistent with U.S. DOE and NREL guidance.
Solar Farm Piles Alabama — Frequently Asked Questions
What types of piles are used for solar farms in Alabama?
Common solar foundation types include pipe piles (ASTM A252 Grade 3) for high axial capacity, H-beam/I-beam piles (ASTM A992) for lateral stiffness,
helical piers (ICC-ES AC358) for sandy or organic soils, concrete piers for permanent heavy-duty support, and sheet piles for slope stabilization or erosion control.
The right system depends on soil conditions, corrosion exposure, and project design life.
Do solar farm piles in Alabama require engineering or can they be installed without a PE?
Utility-scale solar projects should always be engineer-sealed.
Our team provides PE-stamped foundation designs that comply with ALDOT, AASHTO LRFD, and ASCE 7-22 wind design standards — ensuring code compliance and structural reliability.
What pile testing standards are used for solar farms?
We perform load testing to ASTM D1143 (compression), ASTM D3689 (tension), and
ASTM D4945 (dynamic PDA).
Test piles verify capacity before production driving to ensure safe embedment and long-term performance.
How deep are solar farm piles driven in Alabama?
Typical embedment depths range from 8–12 feet, but final depth is determined by soil borings (ASTM D1586 SPT) and verified through test piles and torque or load monitoring.
Depth may increase in expansive clays, loose sands, or high uplift/wind conditions.
What site conditions affect solar pile selection in Alabama?
Alabama presents expansive clays in central areas, variable rock strata in the north, and sandy loams with high groundwater in the coastal plain.
We design for these soils as well as design wind speeds up to ~150 mph under ASCE 7-22.
How long do solar farm foundations last?
Can Foundation Masters handle both design and installation?
Yes. We are an engineering-first contractor offering turnkey delivery: geotechnical investigation, PE-stamped pile design, load testing, installation, and QA/QC documentation for EPCs and developers.
Do you support fast-track or utility-scale solar projects?
Absolutely. Our crews have installed 500+ piles in under two weeks on recent utility-scale builds, with full quality assurance and engineering documentation to keep fast-track schedules on target.
How do I get a solar pile design or bid for my Alabama site?
Contact Foundation Masters with your site borings, drawings, and estimated capacity requirements.
We’ll provide a PE-sealed design, material recommendations, cost estimate, and construction timeline tailored to your site and local permitting requirements.
Alabama Site Conditions We Address
- Expansive clays with shrink/swell behavior (central AL).
- Variable rock strata and shallow refusal (north AL).
- Sandy loams and high groundwater in the coastal plain (south AL).
- Design wind speeds up to ~150 mph per ASCE 7-22.
Typical embedment depths are 8–12 ft (project-specific) with torque monitoring or test piles to verify capacity; documentation is provided to ASTM/ALDOT expectations.
