My mother's house was built in 1977 with a drainage tile around the base of the foundation wall. Lately we have had a considerable amount of water sepage into the basement. I have heard of a beaver system that can be installed. Would this be a good way to fix this problem? Could one install a sump pump in the subfloor of the basement also? We are trying to sell her house because she is a resident of a nursing facility.
Thanks for your help!
