We recently finished construction and moved into our ranch with finished basement. Three rooms have egress windows and window wells that allow "flooding" into the bedrooms with each hard rain. The rain washes away the ground (sand) around the well allowing water to go down under the well and come up through the drain. Water builds up and floods into the bedrooms ruining the carpet, pad, etc. Does anyone have any suggestions to help stop this problem?? We've only lived in the house for two months and it has happend twice already.
