4 years ago I dug out the cracks that were obivious, these are very close by them. I'm thinking the others sealed up so well that the old concrete was honeycomb in a few places that with so much drylock over the years it's seeping thru it. Keep in mind the foundation was poured in the 40's with plywood panels and they used any damn thing they could find, rock, big rocks, brick, even rock that looks like sandstone .
I'm afraid the only way to stop it is to dig into it to see if it was honeycomb when it was poured and chip it away just enough to replace it .
Either that or keep doing the drylock every 2 years...... that gets old.
BTW, can you apply that stuff with a pain gun on the walls, it is rather thick stuff ?
