We have been in this house for about 2 years now with no water problems to speak of. Tonight we had a hurricane like rain storm and where my PVC sewer line exits through the poured concrete basement wall water just gushed through the wall around that pipe and ran down onto the basement floor. This pipe appears to have been stuck through a hole in the cement and then sealed using some kind of gray foam that expands. Obviously this is not a good way of sealing around the pipe where it goes through the concrete basement wall. Do any of you have any suggestions for me to fix this problem the correct way? Is there some kind of hydraulic sealing cement mix I should put around the pipe instead of the expanding gray colored foam? I am going to attempt to attach pictures, but don't know if I know how. Thanks in advance for any help you can provide.
