Re: Rock Foundation Leaks
Grading to allow water draining away from the foundation along with gutters and down pipes directing water away are the simplest things to minimize water infiltration. However, these alone won't prevent water infiltration. Unfortunately the really only way of preventing water infiltration is at the source -- the exterior.
Excavating along the perimeter down to the footings -- install a drain system -- water proofing ( not damp proofing ) the exterior wall --- it's not cheap and invasive --- but --- is the prefered method .
