In 2001, an interior drain system was installed in our basement before we bought the house. Recently I noticed damp carpet in two areas. I pulled up the carpet and found that the concrete used to seal the drain system had a crack in each of the areas where the carpet was damp. I opened up the drywall and the crack did not extend to up the wall so I am pretty sure this is the source of the water.

My question is, what is the best way to repair this? Skim over it? Some sort of epoxy injection? Bust out the concrete in that area and redo it?

Also, we do have a high water table in our area but I am still a bit concerned that water would seep up through this crack rather than runoff through the drain system. Is this an indication that it might be clogged? What would have to be done to clear any blockage?

Thanks for any advice. -- Bud
