I purchased a house last year and only noticing a very, very think
hairline crack in my below ground basement concrete wall (maybe a foot
in length). When a heavy rain occurs (really heavy), some water tends
to get in and pools on the floor. How can I take care of this thin
crack? I've tried some instant concrete powder which stopped it for a
few days but now that is not working. I heard of some stuff I can
inject into the crack and expands, like a needle etc...any ideas?
Some notes: Our neighbours driveway is paved right to the foundation of
our house (long story, but the guy who lived in the house before be let
him do this)....would this be causing the problem? It is not sloping
towards the house and not sloping away either, its pretty level.
I recently installed rain gutters but it didn't help
Any help or insight would be appreciated
