I am feeling much sympathy with retiredladyteacher as I am also battling water issues.
Our house has two high powered sump pumps with backup batteries and drains around the house leading to the pumps. Our ground water level is very high and sometimes the pumps pump year round – except in the drought a couple of years ago. We are also the lowest point on our side of the street.
Despite the pumps, about every 5 years we get torrential rains and a flash flood and water in the basement. We finished the basement 5 years ago when we thought we had done enough waterproofing, but we have had basement flooding twice since then – enough to saturate the carpet but not worse. Yesterday it happened again.
These pictures are not from yesterday but from a similar storm. They show all the water entering our yard from the backyards to the north:
I have two questions. First, does anybody have any ideas about how to divert all this water away from the house? Second, I am pulling up the carpet. What kind of flooring could take seepage of rainwater every 5 years or so? I am looking at vinyl plank flooring installed with adhesive on the basement concrete.
