Three months ago I had my drains replaced under the basement. The plumber broke the basement floor, laid new pipes and then replaced the broken part of the floor with cement.
Since then, I've been concerned that the cement never seems to fully dry out. Last night, after a day of torrential rain, water started leaking out of a crack in the new cement.
The plumber claims it's not his fault. He says cement is not supposed to be waterproof. That there's something wrong with my foundation, because water should not be getting under my house.
If this is so, then why doesn't every house's foundation simply crumble after 3 months?
The house is 40 years old, and there has never been an issue with water seeping up from the cement floor.
Is it possible the plumber should have used a better material? Is there a cement used for foundations that can resist water for more than 3 months? Any suggestions as to what I should do now? Thanks.
