Inside a basement, block wall, efflorescence, homeowner only leaked near corner. They only saw the water at–along the very bottom of where the wall and basement floor meet, got dat?
Here’s the outside of corner, where the water was first getting into the hollow-blocks, caused the efflorescence on inside blocks.
Saw cut a small piece of concrete aka concrete apron, in order to hand dig the biaaatch out and fix the actual problems correctly.
Oh, did we talk the homeowners into any more footage than necessary?
Nope, never have. But many others do that, especially interior basement system cupcakes.
This article, ‘gets’ efflorescence…

…“The best way to prevent the problem is to prevent water from infiltrating the blocks… whenever we see this problem, there is usually a leak somewhere that allows water to enter the block wall…” (see all videos posted, photos as well),
Raising and sloping the grade does not repair/waterproof/tuckpoint whatever the problems are.
Neither does mudjacking slabs and other rookie type suggestions.
Here’s a homeowner, Don Williams, who posted his own leaky, moldy basement problem… appears unfortunately he’ll fall PREY to some interior system company because, as many others do.
2:15 appears someone applied Drylok etc to at least part of block wall, good luck with that.
2:50----3:50 Took some drywall down, some mold and there is at least 2 cracks that are visible inside. Exterior cracks in block and brick foundation walls are NOT always visible on the inside.
Oh, and that moisture barrier? lool Ya mean, Reynolds Wrap! That doesn’t do sqqquat! Another cupcake-idea.
More efflorescence, some mold etc. WHY? Because yet again there were multiple EXTERIOR cracks in the basement wall, hello. NO interior basement system and 69 sump pumps would stop further water from entering hence, would not stop/prevent further efflorescence and mold, nope.
Oh and duh, raising and sloping the grade would not have stopped further water/moisture from entering the actual problems/defects… exterior cracks, so raising the grade would not have stopped/prevented further efflorescence/mold, nope.
