What are post-tension slabs and why do we use them?

In Oklahoma, our soil has high clay content, so it expands and contracts easily with the weather. A heavy rain can cause expansion, and lead to extra pressure on your home's slab. A dry spell can cause contraction, which leads to empty voids underneath. Either way, you're looking at potential foundation and structural issues.  Enter the post-tension slab system. This method allows the slab to move with the soils, which  prevents the slab from separating and causing structural issues.

The residual compression distributed throughout the slab supports the structure on top, and actively resists soil movement occurring under the slab. The StressCon System exponentially increases stability in the normal life of the structure."
