We've been working on a problem of water getting into out crawl space for 8 months now. We've put up seemless gutters, french drains....and sealed places in foundation that water could have been getting in from. We've had 2 days of rain and crawl space is covered (on low end) with water. Yesterday we put a make-shift cove over back of house...thinking the water was seeping in from that end....plastic al the way across the back...this morning I checked crawl space after a night of rain...crawl space has aout 4-5 inches of water.....any suggestions...do we need to dig and check under foundation and footing????
