Expansive Soil Remediation - Ionic Chemical Treatment

Expansive Soil Remediation - Ionic Chemical Treatment

(OP)
My project team is considering ionic chemical treatment to reduce shrink/swell behavior of expansive soil beneath an existing buildings. The subject building is a one-story CMU skilled nursing structure with a concrete slab-on-grade floor and shallow footings. The damage is likely caused by extreme drying/shrink during drought and from high sun exposure.

We completed our geotechnical engineering study and have lots of lab data, but no floor-level survey data yet. Dealing with "moderately" to "highly" expansive soil with a sell pressure of up to 2,800 psf, void ratio of 0.6 to 07, saturation percent is about 75 (now), and activity is about 0.6 to 0.7. I expect the depth of significant seasonal moisture content change is 7 feet.

I would appreciate any stories regarding success or pitfalls and comparison of your project to mine.
