When there is a heavy rain or massive thawing, my basement floods with water entering where the wall and floor meet. The gutters seem to be fine. (I ran water through the downspouts which tie in to drain tile originally installed outside around the foundation, and water exited at the ends of the pipes.) Would hydraulic cement or epoxy around the inside perimeter (maybe after chiseling out a "V") solve the problem? There's no sump pump.
