Hello,

I have a small window into my crawl space area that has cracked
masonry around it. When it rains, water flows into the crawl space
area via these cracks. I'm not sure how I should repair this. Is
there a special crack filling compound I can use on the masonry? How
about waterproofing paint to seal it up?

I've been to Lowe's and see that they have:

1) UGL Drylock - Latex Based Masonry Waterproofer
2) UGL Drylock - Oil Based Masonry Waterproofer
3) UGL Drylock - Fast Plug Hydraulic Cement

What is the difference between these, and are they any good? Is there
a better product out there for what I'm hoping to do (ie: seal and
waterproof this window).

Thanks
Sam

You don't say how big the cracks are, or where exactly they are
located.

The two waterproofers are intended to prevent moisture flowing through
undamaged masonry. They won't seal any but hairline cracks. In
general, the oil based version works better than the latex, but smells
horrible and is harder to clean up after. They are really
dampproofers, not waterproofers in that they won't stop serious
amounts of water against the wall.

The hydraulic cement is designed to fill holes and larger cracks. It
sets chemically and can be used even on wet materials. It swells
slightly when it sets so it seals tightly. You have to work very
fast, it sets in minutes.

The hydraulic cement should only be used on cracks or holes within the
masonry, not between the masonry and the window or other non masonry
material. For sealing cracks between dissimilar materials, use caulk.
Caulk can tolerate movement that occurs between dissimilar materials.
For this you would want a polyurethane caulk made to stick to masonry
surfaces. The surfaces generally have to be dry (and above freezing)
to caulk.

All of the above assumes this problem area is inside or outside above
ground level. If it's outside below ground, you need a different
approach.

Hope this helps,

From the way I've used it, the first two are for painting on the masonry to
prevent water from seeping through it. The Hydraulic Cement is for patching
cracks and what I would use for the repair.

*What exactly is the "Masonry" around the window. Is it poured cement,
concrete block, cinder block, brick or stone? How long and wide are the
cracks? Do you have some pictures to post?

If it's hairline cracks, waterproofing paint might work.

I had some thin cracks in a wall, went to Home Depot. The woman in
the paint department said that the HD brand worked better than the
other one they sold, and the HD brand was more expensive! (when does
that ever happen?)

I bought it-- it's thick paint, you paint two coats. I did it
figuring it was easier and worth the try, and had low expectations.
But it worked very well-- stopped all water seepage through the wall
(you can't use it on floors, by the way, as it's too slippery)

I've been to Lowe's and see that they have:

I used UGL in my poured-concrete basment walls (Two of my basement
walls are underground and the other two walls are above ground.) After
16 years there is some cracking but my basement has been dry due to
landscaping changing and adding longer drain lines, extending existing
downspouts, etc. Seeing a picture would help. Do you have
spaulding? Watch carefully where the water is entering and where it
puddles nearby, you may need flashing, better overhang, etc. Sealing
a crack or two may be just the beginning of a larger project. There
are a number of caulk products available that are specific to masonry,
and that may be what you need. Follow the preparation instructions
carefully.
