Traditional Concrete Foundations
A common foundation method for certain site and engineering conditions
Poured concrete foundations and stem wall systems are still used on many projects and may be required in some cases depending on site conditions, engineering, or local requirements. They can be a solid solution when the job calls for them.
PowerFrame is a state-approved foundation system designed for speed, strength, and simplicity. It offers a clean above-ground installation approach with no unnecessary concrete on many projects, while delivering strong performance in seismic, wind, roof load, and uplift conditions.
The key is choosing the right foundation for the home, the property, and the conditions on site. That’s where experience matters. We help owners, builders, and developers determine whether PowerFrame or a traditional concrete system is the better fit.
