My basement was poured about a summer ago. But all around the corner i have open gaps that i want close. Especially the exterior walls facing the front and back entrance.

I don't have any water leaking in but the basement get damp and that weird basement smell.

i was told by a contractor that i need to seal about 4 feet from the floor to stop the moisture from coming up.

Right now it is raining in NYC and the corners that are not sealed is moist.

So far i have dry lock Pro

I will also be chipping away all the old compound off the walls.


What cement, Portland or mortar would be best suitable to seal my walls and gaps.

Will post pics soon. phone died.

When it rains check outside or look outside to see if water is pooling up against the house. Fix that if needed so the water runs away quickly.

I think the Dry Lock Pro should stay in place and not be chipped off.

Not sure what kind of cement should be used to seal the cracks.

Too late now but the outside surface of the foundation should have been waterproffed with that black coating prior to being backfilled The Dry Lock Pro on the inside surface would have been the second best solution.

With the corner down where the floor and wall meet getting moist, you may need a perimeter French drain and sump pump.
Do a test excavation on the floor slab about 8 inches square and about 8 inches in from the wall to see if water rises up close to the floor surface on a wet day.

I don't have any water coming in. it's more of the wall needs to be sealed. i will post pics in the morning.

How Parge stone basement walls for water proofing, odor and moistness?



Is this a stone foundation with a new concrete floor? And you did not put in a water management system?

Waterproofing should always be done on the exterior!
Drylok is best for priming below grade masonry but shouldn't be relied on to stop anything more than dampness.

impo, drylock ( 'pro grade' is a misnomer as no pro would pick the stuff ) is good if 1 owns the co & wants a bigger boat,,, eg, i don't think allanj does this work for a living & mark's a painter

having posted the above, in full disclosure & fairness, i have used drylock on our own home to recoat a front buried cmu wall,,, bride didn't want to invest in a sub-floor leak management system & i couldn't convince her even tho that's how we make a living,,, nevertheless, i did paint the wall & it did come out fine,,, now that the house's for sale, i again repaint the same spots which show efflorescence again & again
instead of my work being once & done, now i have to revisit the :vs_mad: (*%#@%^*(^%$ :vs_mad: wall 1 hr before any r e broker comes to show the house,,, this is not a pro's solution, the only 1 making any $ is drylock, & i keep my mouf shut concerning my bride's sense of thrift
ps - for once in my life, i was smart enough to not remind bride of my original advice to repair it properly
