I purchased a house last year and discovered over several months that I live in an area with highly expansive dark clay soil. This has caused cracks in my floating slab foundation, drywall, and of course affected doors.
I'm looking at solutions to this problem. Neighbors have had piering and mudjacking done with some less than ideally successful outcomes.
I see it as two problems. One the soil, and one the existing damage.
I've been trying to get a company that uses Ionic Clay Stabilizers to give me a quote, but have had challenges getting someone that serves Kansas.
In my research a lot of the advertising on Polyjacking seems to suggest that foams/and or resins provide soil stabilization under the house, however my intuition is a bit questioning of this as the expansion and contraction of the soil seems like it would still cause issues unless the resins and foam cause the entire subsurface to be more resilient to expansion.
I found this article which also seems to suggest poly improves soil stabilization.
Can anyone enlighten me to if polyjacking simply fills voids and corrects damage or additionally mitigates on going damage of expansive soils?.
Related guidance, experiences, and info/advice are also appreciated. I've currently gotten a quote for piering (16 piers) and polyjacking, but I want to make sure I understand my options and have the best chance of a good solution.
