Esshup........As expected he said solving the problem can only be effectively done by digging out the rock corner 2-3 feet, and refilling the whole area with bentonite layer then layer in 2-3 feet of clay soil with a sheepsfoot. Since we will be digging the foundation for the house, he said the test samples they took showed I had real good clay about 2 feet down. So, at least, I have a good, close source for the clay.
I've been through two episodes of drill and grout and it works for awhile then the water finds a new route through the limestone.
More rain today and it is full & great looking. Later this summer that project will begin.
