When it rains alot I get a puddle of water in one spot of my walkout basement. It appears to seep up through the floor. I have a grinder pump for my sewage that has not been filled around and notice the water level rising around it.
I have started to finish my basement but know I will need to address this problem before installing flooring.
Relevent Info: No sumppump (house built at top of a hill), House ~5yrs old, sealed outside (black sealer), tile tile around front and sides of foundation, poured concrete walls and floor (I was going to attach a picture but it asks for a url and it is on my harddrive - it would have show that my back wall is ~4 high of poured concrete that is below the floor, then at floor level it is studded with 2x6's)
I have a feeling the problem is with my ~4 ft underground wall. If that would help visualize, I can get some pictures that were taken during the construction if someone explains the best way to do so.
What can I do to stop this?
