Digging the foundation...

So we did down at centre front of the house, thru the landscaping, to the stone.
We reach the insulation.
Cut thru the insulation, expect to see gushing water draining from under the house. Nothing. Not even any dampness?!?!?!
The stone is bone dry - no sign of any wet. Absolutely baffling!

We filled it all back in and continued to scratch our heads!
