great product for filling gaps in cement between house and sidewalk

Great product. We had gaps around the perimeter of our house between the house and concrete. We used a spool of foam and then many tubes of this filler on top of the foam. It set up on top of the foam and worked beautifully.

I keep purchasing this product

My experience with this product has been great. I have been dealing with a leak where the concrete vault of my Bilco entryway to my basement butts up against my poured concrete basement wall. While this sealer, has exceptional expansion and contraction properties to accommodate temperature fluctuation, it firmly adheres to the concrete surfaces and requires an extensive effort to remove it once it cures in place. I just purchase a 12 tube case for other work around the house.

Great product.

I ordered this product for outdoor fixture. Unfortunately our weather in NY has changed a lot and for some reason I was getting water into the apartment to to some crack on outdoor walls. This did the trick and sealed all this cracks. Looking for something that does the work on sealing. Look no more !!

I ordered three boxes of this. Two of the boxes had 24 tubes in them, which is correct. The other box had 15 therefore missing nine tubes.
