Permanent Wood Foundations
A foundation is more than structural support, it sets the stage for durability, comfort, and long-term performance. Permanent Wood Foundations (PWFs) offer a proven, engineered alternative to traditional concrete foundations, combining strength, flexibility, and energy efficiency. Foundation King of Oregon specializes in the design and installation of Permanent Wood Foundations for residential and commercial applications across Oregon.
Permanent Wood Foundations are built using pressure-treated lumber and engineered wood components designed to resist moisture, decay, and soil contact. When properly installed, they provide exceptional structural integrity while allowing for faster construction timelines and improved thermal performance. PWF systems are recognized by building codes and have been successfully used in North America for decades.
Whether you’re constructing a new home, addition, or replacement foundation, Foundation King of Oregon delivers expertly engineered wood foundation systems tailored to site conditions, soil composition, and project goals. Our team ensures each foundation is properly drained, insulated, and reinforced to provide long-lasting performance in Oregon’s varied climate.

What Is a Permanent Wood Foundation?
A Permanent Wood Foundation is a load-bearing foundation system constructed from preservative-treated lumber and plywood, designed for direct contact with soil. Unlike temporary wood structures, PWFs are engineered for long-term use and meet strict building code requirements when properly designed and installed.
These foundations rely on controlled drainage systems, granular backfill, and moisture barriers to maintain durability. The result is a strong, flexible foundation that resists cracking, accommodates minor soil movement, and provides superior insulation opportunities compared to traditional concrete foundations.
Permanent Wood Foundations are ideal for basements, crawl spaces, additions, and replacement foundations where speed, performance, and energy efficiency are priorities.
Key Advantages of Permanent Wood Foundations
- Structural Strength: Engineered systems designed to support residential and commercial loads
- Moisture Resistance: Pressure-treated materials resist rot, decay, and soil contact
- Energy Efficiency: Easier insulation integration for warmer, drier living spaces
- Faster Installation: Reduced curing time compared to concrete foundations
- Design Flexibility: Ideal for additions, remodels, and site-specific conditions
