Answer: 
After it dries it is waterproof. This is crack seal. As long as the water is not under pressure it will prevent water entry. Your description of "fast flowing" water makes me think you have more than a crack. Also this works best on horizontal surface cracks. It is too thin for most vertical surface cracks.

Answer: 
this product is for flat horizontal surfaces with cracks, it goes on with a very liquid consistency. You can not use this on a vertical surface, although there are other products for that. Hope this helps.

Answer: 
No, QUIKRETE Concrete Crack Seal is not designed to seal against water intrusion. It is designed to fill cracks on any horizontal concrete surface. This problem would be better addressed at the cause, through sloping land away from the house, ensuring gutters are directed away from the house, etc. Please discuss your issue with a contracting expert or call QUIKRETE directly.

Answer: 
in my garage I have cinder blocks with cracks and used it. its runny but take your time and it will work. I was able to fill them in. I used a small trowel and gloves to push it in.They do make a concrete in a tube and you put it in a caulk gun. May be better.

Answer: 
QUIKRETE® Gray Concrete Crack Seal (No. 8640) is a latex emulsion that will flow into cracks, however it may not completely self-level. The cracks should be overfilled slightly to allow for shrinkage If you are interested in a self-leveling product with more flexibility then QUIKRETE® Polyurethane Self-Leveling Sealant (No. 8660) is recommended.

QUIKRETE® Gray Concrete Crack Seal (No. 8640) is a latex emulsion that will flow into cracks, however it may not completely self-level. The cracks should be overfilled slightly to allow for shrinkage If you are interested in a self-leveling product with more flexibility then QUIKRETE® Polyurethane Self-Leveling Sealant (No. 8660) is recommended. When repairing cracks in concrete, we always recommend trialing a small quantity of the repair material in a discrete area, and allowing it to cure for a minimum of 24 hours to determine whether the color and overall appearance is acceptable before using the material in less discrete areas. If the cracks in the concrete are due to material settling, the settling may continue, causing the cracks to propagate through the repair material.

Rated 3.3 out of 5 by 30 reviewers.
Rated 5.0 out of 5.0 by Great product. While cleaning out the shed, I fount the unopened bottle of sealer. It was so old that it had settled.. After stirring for about 30 mins I used it to seal a visible crack across 2 car driveway.. I fill the crack and feathered about 1/2" each side.to 1/16" thick...The truck tires did not disturb it and so much is left over, I will give it to my neighbor .. August 1, 2016
Rated 4.0 out of 5.0 by Great for driveways and patios The other people on here don't know what their talking about, easy to use, yes it does have dried material mixed in from sitting on the store shelf, deal with it, does exactly what it says and installs quick and easy July 23, 2016
Rated 5.0 out of 5.0 by Concrete Seal Easy to aoply and smooth out. Dries well and easy to paint over. July 25, 2016
Rated 5.0 out of 5.0 by Works well, easy to use I previously used a product for use with a caulking gun, and found that it hurt my hands after a couple of tubes. This stuff almost pours out and levels well. It is important to keep it flowing or put the cap on right away or it starts to dry inside and clogs. July 12, 2016
Rated 5.0 out of 5.0 by Good stuff This stuff is great just open and point into crack June 21, 2016
Rated 2.0 out of 5.0 by Concrete crack filler Product liquid was too thin to fill a 1/4 inch crack without leaking out of the crack. Followed the instructions especially when it came to shaking the bottle to mix the contents. July 13, 2016
Rated 5.0 out of 5.0 by Concrete Crack Sealer - Easy and quick to use to repair cracks This comes with an easy to cut top so you can pour into different sizes cracks. Pours into cracks and hardens fast. July 12, 2016
Rated 1.0 out of 5.0 by Don't waste your money! This stuff just creates a rubber barrier between whatever you squirt it on. It comes off with rain. June 14, 2016
