Will this stop water from leaking into the basement?

I have water leaking in from the bottom cement block where the wall meets the floor. Can I cover my basement wall and corners with this to stop water from leaking in?

Foundation crack

I have a crack in my foundation wall that never dries. It's a very small crack but it never dries. A good amount of water comes in and I'd put a water proofing over it once it cures. Will this hold?
Asked by: Southside
QUIKRETE® Hydraulic Water Stop Cement is designed to be mixed to a heavy putty consistency for use in filling active leaks in small cracks or holes in concrete and masonry – a golf ball size mix is appropriate for most applications. QUIKRETE® Hydraulic Water-Stop Cement is not meant for applications to flat surfaces, and cannot be used for resurfacing or coating a surface or large repairs. Note that prior to making the repair, the substrate needs to be clean, unsealed/uncoated, and free of any dust, loose debris, and any other bond breakers. It is always difficult to get a color match when making repairs. We always recommend trialing a small quantity of the repair material in an inconspicuous area, and allowing it to cure for one week to determine whether the color and overall appearance are acceptable before using the material in less discrete areas. We typically recommend that QUIKRETE® Hydraulic Water Stop Cement be cured for at least 28 days prior to applying a waterproofing coating. Please consult with the manufacturer of the waterproofing coating for their recommendations on how soon their material may be applied over freshly placed concrete.

20 lb. Hydraulic Water-Stop Cement is rated 4.3 out of 5 by 32.
Rated 5 out of 5 by from This stuff is awesome Had water in the basement, seeping in from cracks and seams where the wall and floor meet. Applied this water stop cement. It immediately stopped the water. I even used it where there was a some water. Like other reviewers said, it sets up fast so you have to work fast and do it in small amount. I found the easiest way to have it mix up with water to to put water first then add the cement until it's to the form that you want. I also just put the mix into area where water was coming out and mixed it there. Worked great too! I can not be happier with this product. By the way, I had never used cement before and not a very handy person. If I can do this, anybody can.

Rated 5 out of 5 by from I love this stuff I used this to stop seepage between the base of a concrete block wall and a concrete slab in a basement. I loved working with the stuff. It sets up in a very few minutes, even in cool temps, so don't mix much. It is very sticky and stays where you put it. I placed it in the corners and used a 2" piece of PVC to trowel it into a fairly attractive, very functional concave shape with lots of sealing surface. Two cups would get me a good 3 feet of corner filled. The next batch blended well into the previous one. It took about 25 pounds to make it around the perimeter of a 15x15 foot basement using this technique. The second tub set up considerably faster than the first, despite identical temperatures and moisture.

Rated 1 out of 5 by from Not worth your effort or money I'm a homeowner that has waterproofed over 100 feet of basement walls in 3 homes. These projects have spanned 25 years, all have remained dry to date. This product is no more then ordinary cement. it does not waterproof anything, least of all a basement wall. Don't waste your time and money using this product to waterproof your basement walls. This weekend will be spent hammer drilling this stuff and starting over.

Followed directions from start to finish. Leak pushed all material out of crack within minutes. Tried mixing it a little "hotter". Same results. Warmed up the are to be used on, and also had light heat applied near area. Same results. The purchase was a waste of time.

The other big hardware store sells the same brand, but with a slightly different formulation that cures in 1 to 2 minutes, which is just not enough time and forces you to work with very small batches. This 3 to 5 minute curing time available with the Home Depot version is much easier to work with.

Rated 5 out of 5 by from Works perfectly. Our front yard flooded during a recent storm and water started coming in the basement through cracks. Had to make a quick trip to Home Depot for this stuff. Applied a patch to the cracks and the water stopped almost instantly.

Used this product to seal and patch up cracks that showed up in a much more expensive product used to final coat pools of a water fall. I should have used this Quickrete product first and foremost.
