My house is 2 years old,I had it built. within 6 months of moving in my basement flooded. I sued Keystone to fix the problem, and fought over their solution, I folded to their solution after lawyer fees racked up. they did there fix, and it, flooded again (4.5 feet of water!), I added another sump pump, 2 inch pump and have an 1/4 inch pump. With a backup generator. I thought I was good, today it flooded again. The foundation has Delta MS on the outside. It looks like this time the water came in through the area between the wall and the floor, or came in through the bathroom rough in grinder pit (all unfinished) I would think that the water would flow up through the sump pit before coming up through the floor, several questions, did the water come in through the sump pit, grinder pit, or from the floor, I re-graded 2 times, so it can't be that. the sump pit area was dry before the water rushed in and wet in other areas of the basement. My neighbors downspouts are pointed at my house as well as his sump pump ,I tried to get permission to move those to the back of his yard but he would not let me ( one of Keystones fixes) I'm not sure what to do, and don't have much money as I am off due to the gov't shutdown, so any advice sent to me would be a big help.
