Post-tension foundation design in Aliso Viejo offers superior performance for residential and commercial slab-on-grade foundations, particularly in expansive soil conditions common throughout South Orange County. Our licensed Professional Engineers with over 20 years of foundation engineering experience serve homeowners and developers throughout Aliso Viejo, Laguna Niguel, Mission Viejo, and surrounding communities.
Post-tensioned (PT) foundations use high-strength steel tendons stretched after concrete placement to create a compression force that resists cracking and differential movement. This technology is particularly valuable in Orange County's expansive clay soils, providing durable, crack-resistant foundations.
What Is Post-Tension Foundation Design?
**Direct Answer:** Post-tension foundation design involves engineering concrete slab foundations reinforced with high-strength steel tendons that are stressed after concrete curing. This creates a compressed, crack-resistant slab system ideal for expansive soils. In California, PT foundations require PE-stamped design meeting CBC and PTI requirements.
Post-tensioned foundations offer key advantages:
- **Crack resistance** through compressive stressing
- **Reduced slab thickness** compared to conventional slabs
- **Expansive soil performance** with better deflection control
- **Span capability** for larger unsupported areas
- **Long-term durability** with minimal maintenance
