basement water seepage under concrete porch
During a rain, or shortly thereafter, we have water seepage on the basement floor as well as dripping from the concrete ceiling in an area that was once an old coal bin and is located under the concrete front porch. Any ideas on how we can we eliminate this seepage and waterproof the concrete front porch?
P.S. We don't believe the water is coming from the foundation as all windows are glass block and the basement was professionally waterproofed with drainage tile placed inside and outside, as well as vapor barriers and 2 sump pumps installed.
