Foundation Types for Solar & Structures
The foundation is chosen from a soil investigation, matching type to bearing and uplift needs.
| Type | Installation | Best for |
|---|---|---|
| Driven pile | Hammered/pressed in | Good drivable soils |
| Bored pile | Cast in drilled hole | Hard/variable ground |
| Ground screw | Screwed in (helical) | Fast, low-disturbance installs |
| Pedestal / pad | Cast concrete footing | Near-surface bearing soils |
Wind uplift often governs pull-out; only a geotechnical test can confirm the right choice.
Frequently asked questions
- Which foundation is fastest to install?
- Ground screws avoid concrete curing and civil work where the soil suits, giving fast installation.
