Expansive soils—especially the fat clay common throughout Oklahoma and Arkansas—pose a serious challenge to residential construction. These soils swell when wet and shrink when dry, creating powerful forces that can crack and shift conventional foundations. At Stresscon, we specialize in post-tensioned concrete systems that are specifically engineered to withstand these soil conditions - making them an ideal, cost-effective alternative to traditional rebar-reinforced foundations.

The Expansive Soil Problem

Fat clay soils can expand with enough force to lift concrete slabs and crack foundations. Left unaddressed, this leads to costly repairs, reduced home value, and long-term structural instability. Building a strong, resilient foundation starts with a design that acknowledges the local soil behavior—and that’s where post-tensioning shines.

Why Post-Tensioned Concrete?

Post-tensioned concrete is a proven solution for managing the effects of expansive soils. Unlike standard rebar foundations, which rely on passive resistance, post-tensioned systems actively compress the concrete slab, increasing its load-carrying capacity and resistance to cracking. The result: a thinner slab that performs better over time.

Key Advantages:
- Cost-Effective: Requires less concrete and reinforcement—reducing material and labor costs.
- Engineered for Soil Movement: Custom-designed for the specific soil conditions of your site.
- Improved Durability: Greater resistance to cracking, lifting, and long-term shifting.

In-House Engineering & Exceptional Service

At Stresscon, we don’t take a one-size-fits-all approach. Our in-house engineering team works closely with builders and homeowners to develop tailored foundation designs that take local geotechnical reports and soil data into account. Every slab is engineered to perform under the unique stress conditions of the project site.

And our service doesn't stop at design. We support you through every step—from layout and tendon placement to stressing and inspection—ensuring accuracy and accountability at every phase of the build.
