We recently had three sides of our detached bungalow dug up, and a new weeping tile system installed. Foundation (concrete block) was parged, and a brown membrane was drilled/bolted on, then caulked all around. The company that did it seemed to do a good job, from what we could tell. Our basement had to be completely gutted due to mold, so we decided to check and make sure there were no leaks after the weeping tile was put in. Heavy wetting of the foundation with the garden hose revealed two leaks in two spots on the same side of the house: by the porch and by the gas meter. My question is, how could this happen? Could there possibly be residual water that was stored in the concrete blocks? Could there be other residual water sitting somewhere that's making its way in? I'm so baffled. I guess we'll have to call them back and have it dug up again.
