Yes it is a polyurethane sealant but it has not been tested for radon reduction. Sikaflex Construction Sealant has been seen to reduce radon. This sealant is also a polyurethane based product.

Only its viscous nature will slow its flow on anything but flat surfaces.
More than a couple degrees and you're in trouble.
Great SELF-LEVELING crack filler.

Answer: 
Thank you for your inquiry. Actually, if you have a slope at all, I would not use the Sikaflex Crack Flex Sealant because it does have a steady flow and could puddle. Instead, try Sikaflex Concrete Fix. It's a non-sag sealant with similar properties to Crack Flex. We recommend you follow the directions on the product data sheet. You can download it at usa.sika.com/retail, click on the magnifying glass on Read More

Answer: 
It flows pretty well. You best bet might be to apply in stages starting from the bottom. But I still wouldn't use it on very steep of a slope.

Hi,
I have a corner lot, so a lot of sidewalk to take care of. I often get grass and weeds coming up in the expansion joints. Would it be a good idea to pull the weeds, and seal the joints with this? Would there be any downside to that?
Thanks!

Hello, thank you for your inquiry. Before you caulk, you will need a clean and dry joint. Remove all dirt and weeds from the joint. Our Sikaflex Crack Flex (textured finish) or Sikaflex Self Leveling (no texture) can be used, as long as the surface is flat. These products are self leveling so no tooling is required.

No downside, but expensive and a lot of work when compared to a bottle of pre-mixed vegetation killer [which is what I use for that purpose].

Rated 4.6 out of 5 by 22 reviewers.
Rated 5.0 out of 5.0 by Great Product Preparation of the crack was the hard part. This sealant is somewhat self leveling. A putty knife is required. You will want to check it as it sets up as it does flow into the crack and you may need to add more sealant and smooth with the putty knife again. It was slower curing than I expected. This was done in my son's house in Phoenix, AZ where it is dry, so I expected it to cure faster. Not drying so fast may be good if it is a long crack as it gives you time to work with it smooth it out. The crack had variations in width to be fair to the product. I had very satisfactory results. Home Depot sells a pair of Gorilla gloves, that worked well in protecting my hands and survived to protect another day. I cleaned the putty knife with a wet paper towel. Cut the very tip of the tube as it will give you more control of the sealant. May 31, 2016
Rated 4.0 out of 5.0 by fixed my crack I had a big nasty crack in my concrete driveway, I used this product to fill the gap. The directions say to just put it down on the crack with a caulking gun and let it sit. It is self leveling. After the fact I kind wish I would have used a putty knife on it to level it out. It kind has a little pump where the crack was. Look at my pictures and you can see what I am talking about. It seems durable though, and I don't expect it to fall off or anything. All I did for prep was sweep the cracked part of the driveway with a broom. September 25, 2013
Rated 5.0 out of 5.0 by Great product Great product! Not sure what to say about it.... it works. Easy to apply using a caulk gun, and it sealed my concrete perfectly. Used it on both the interior and exterior of my basement to prevent leaks. Had it there several months now and haven't seen any leaking. Now I am just trying to fill the minimum required characters because I have nothing more to say about it. December 4, 2015
Rated 3.0 out of 5.0 by OK but tedious with caulk gun This product performs as advertised. My only complaint is using a caulk gun can make this job slower than it should be job. I used it for expansion joints and it was difficult to do a professional looking job because of the nature of using a caulk gun (unless you use one regularly). I went though 2 tubes of this product before I stumbled across another brand that comes in a 32 oz plastic container. You squeeze it out like wood glue. I simply found the 32 oz container much easier and quicker. It also leveled out quicker than what came in the caulk tube. You may be perfectly fine with using a caulk gun, but I preferred the plastic container with the resealable cap.. It was also much cheaper. March 30, 2014
Rated 4.0 out of 5.0 by Sika seals shallow sidewalk splits Sikaflex flexible sealant is a cinch to use, and provides a nice, durable repair to those smaller cracks that develop in your sidewalk or driveway. I also like that the sealant, once cured, remains flexible, allowing for continued seal, even with seasonal movement of the concrete. A word of caution, however-- Sikaflex does work on cracks up to 1" wide, but only up to 1/2" deep-- a very small window of usability, in my opinion. If the cracks being repaired are deeper than 1/2", then you'll have to find a different product.. For SMALL sidewalk and driveway repairs, I'd recommend this product. August 6, 2013
Rated 4.0 out of 5.0 by Not So Long-Term I use this product to fill the "not-so-hairline" cracks developing in my exposed aggregate driveway. The best feature is its 'self-leveling' attribute ... squeeze it not-too-carefully along the crack and don't mess with it. It 'levels' so well, you'll probably need to go back over the cracks in a day or two. Needs improvement areas: the 'sand' color is too bright for exposed aggregate; its 'plasticity' lasts only a few years after which the normal expansion and contraction on the aggregate will crack the seal and you'll need to reapply. But I haven't yet found a better product. November 13, 2013
Rated 5.0 out of 5.0 by Best In Class - Have Used Sika for 5 Years I've been using this product for over 5 years to seal driveway cracks and it dispenses and holds up much better than 2 similar products I have tried. The competing products are harder to pump out of their cartridges (which is important if you are using a lot of tubes) and they do not have the flexibility and long-term elasticity of the Sika sealant. Be sure when you use this that you first fill the crack with a pre-filler (my favorite is limestone base because it compacts) else you'll waste the sealant down the crevice of the crack, which is expensive. Also, if you live in a cold climate, never let the sealant fill above the level of the concrete, else your snow shoveling equipment will snag it and pull it out. June 4, 2013
Rated 3.0 out of 5.0 by not what I expected from Sikaflex I have used Sikaflex SL Self-leveling Sealant before and really like it. This time I decided to try the Sikaflex Crack Sealant which sounded like a better product for my use. When I opened and began to use the first tube, the product came out as a nearly clear, thick fluid---not a gray, cement-like materal as expected. As I continued to use the tube, the caulk became more what I expected, but very thick. Two of the four tubes I used were like this. It also was not as good at "self-leveling" as the previous product I had used. August 22, 2012
