Basement Sealer...what Product

Gordo

I have a full service client who called and wants his basement 'sealed' to prevent water from filling into this space.

Here in So. Va. we only have basements in a certain area of Norfolk.
I do not have any experience with this problem and would like to hear solutions from those with any knowledge.

The basement stays dry 99% of the time. The other 1% it will fill with 1/2" of water (usually after 6-10" of rain due to hurricanes).

Home built circa 1915. Seems as if water is coming up from below.

Drylock or Thoroseal.

I googled basement sealers and saw two products that you spray on. They reportedly will seal the capillaries of the concrete up to 4-6", thus eliminating any water penetration via that route.

All cracks are to be epoxy filled prior. Another benefit with this product is it eliminates radon migration.

Thanks T, I will research those. Still looking for advice from anybody.

I coated half a basement with Drylok before finishing it into a family room.

The basement had been similar to yours - 99% of the time dry, but in the heavy/long rains it would have some seeping.

I never got a callback due to water, and it's been 5 years. I'm really skeptical about any interior waterproofer, but UGL advertises that it will stop hydrostatic pressure up to 10 lbs and I guess the claim holds water, at least under the ideal conditions.

Yep, I am very skeptical about any product that promises to provide negative side protection, but Drylock has worked for me for 20+ years, with no issues.

Is there a cutout in the slab with a sump system?

I cannot remember specifically. I have worked in other homes in this area that do have sumps. Most of those homes flood on a more regular basis. The street this home is on is of the dryier variety.

I will get more specifics on Monday.

Is there something to know in regards to sump systems? Obviously, this is a hole where water can pressure up.......will there be any negative consequences using the drylock?

Check this product out. What do you all think? Do not let that hot chick with the shirt falling off sway your opinion.
