Expansive Soil And Foundation Cracks Video

i think this is a laudable idea but what about swelling as water gets into it. Can it affect the foundation? or shd there be limit to water ingress that should be based on its natural moisture content, which should be determined during ground investigation? thanks

please do not recommend to people to "wet" the expansive clay beneath their home. This is antiquated thinking, and does not work. Instead, FIX the clay with an ion-exchange fluid, injected into the clay. it will rob the clay of its electrical charge, permanently. The clay will not attract water, and movement will stop. THEN permanent repairs can be made. We have been manufacturing this technology for 40 years.
