in Alexandria
Our basement floods when there is a lot of rain. Luckily, the only area that gets wet is our basement bathroom which has a tile floor. This has been going on for 3 years or so but has gotten worse in the last year (i.e., it happens more often). We have had the City of Alexandria come to see if it's a sewer problem - it is not. The water is clear and the City engineer thought that perhaps it is coming up through the floor. Please help! Thanks.
