Foundation Design for a New Home
Engineered footing, slab or basement foundation design based on your soils, loads and local code.
What the work involves
Many homes can use prescriptive foundations from the residential code, but expansive or soft soils, slopes, high loads, post-tensioned slabs and areas with special requirements call for engineered foundations. The engineer uses a geotechnical report and loads to design footings, slabs, piers or basement walls and stamps the drawings.
Local conditions we plan for
- Expansive clay soils and foundation movement
- Hurricanes and coastal flooding on the Gulf Coast
- Flash flooding (Hill Country, Houston)
- Karst in the Edwards Aquifer region
Building code: 2012 IBC/IRC listed at the state level; local jurisdictions may adopt newer editions (ICC adoption chart, April 2026).
When you need it
- Expansive clay, fill or soft soils
- Post-tensioned slab common in your region
- Hillside or stepped foundation
- Building department requires engineered foundation
- Heavy or unusual structure loads
