Sorry to hear that it was sounding like an awesome project.I hope you figure something out.Maybe an extension on the house with a designed foundation is in order
Well hell sakes man, Y'ALL'RE IN Texas...
PreStressed Reinforced Concrete Slab...
Make the Base of the system 100" x 36" x 12" PSR Concrete and build the stand off that.
Don't matter where the house settles to ...your Rock will still be standing...
well the problem is from the lack of rain. The soil is moving away from the foundation and the corners of the house have cracks, its going to be around $17,000.00 to repair.
