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.

Yeah my main concern would be the foundation, I've been taught not to have any water in the ground as the water table may affect the foundation structure?

I would suggest this away from the home, if tree roots and larger shrubs were not getting water.

However wetting clay can lead to so many problems adjacent to the home. If there's a basement, hydrating the clay will cause it to expand both vertically and horizontally. The horizontal expansion pushes against the basement walls causing them to bow and/or crack. Thorough hydration of clay below interior slabs will cause the slabs to heave.
If the home is settling as a result of shrinking clay, a better approach is to support the foundation with helical piers to prevent settlement.
