I looked and didn't find the answer so I apologize if this is a repeat.
I have a 70 year old house that after extremly heavy rains and some water seapage at the floor wall joint where there was no longer any drylock. This has happened only once and the storm was blowing winds where blowing onto the house. My question is would you just re-drylock it and look into sump pump etc. in the spring? Or just drylock and see if it leaks again. I built up around the house and sealed concrete cracks around the area, extended downspouts etc.
you...like anyone else, had water ENTER because there IS a direct opening(s)on the outside of where you saw water at the cold joint inside...know what i mean?
if you are ONLY getting water on the floor where the wall `n floor meet, and its ONLY in 1 area, then it came in from either/both A)opening(s) on the outside of the wall below grade B) opening(s) ABOVE ground level incl`g around basement windows,any vented or screened window(new or old!),open mortar joints/porous-cracked bricks,opening where a hose for central a/c enters the house etc.
You can drylok all ya like,any paint or inside dewatering system does not stop water from entering the basement through outside openings. And if/when ya dont stop water-moisture, then one will not stop/prevent mold,efflorescence,radon,termites-insects,hydrostatic & lateral pressure and the possibility of wall deterioration.....find the opening(s) and fix.
