Asked by: Rob
If the cut is four inches deep then it would most likely work depending on the width of the cut you may have to double it. If you are asking about a four inch wide cut then it would need multiple layers to fill the gap.

How much will this compress (after installation) if the slabs move or expand?

Asked by: 35th
Installed last summer. Have not seen any compression. To ensure product did not lift, covered with concrete caulking. Looks great. Held up through New Jersey winter. Product can be cut to ensure tight fit in joint. Highly recommend.

Rated 4 out of 5 by from Seems to be working as a joint material About 10 years ago, I decided to pour concrete slabs beneath my canales. So the water that runs off the roof falls on a concrete slab. 10 years ago I used the asphaltic fibrous joint material between the concrete and the house. Most of it has deteriorated to the point that there is nothing left. I had several other canales that I never put a slab under, but decided to do that this summer and I also decided to build a sidewalk along a portion of the house, so I bought the foam to try out. See attached pictures of the foam joint material, which seems to work ok. You need to glue it to the surface, in my case the house,to keep it in place where as with the aliphatic fibrous material, it was much stiffer and did not have to be glued as much. The aliphatic material could get by with only 3 or 4 spot glues just to keep it from falling down while pouring the concrete. If you are going to screed off the foam material it needs to be continuously glued near the top so it doesn’t push down while using it as a screeding surface. One of the pros to the foam is it will easily go around a rounded corner. Again see picture. I also found that it is better to put a bead of caulking or glue material all along the top of the foam to keep concrete and aggregate from getting behind it, since it is so much more flexible than the other joint material. Con: The need for gluing and calking requires additional time to allow the glue and calking to dry good before doing the concrete work. 5-10 years from now, I will know if this new foam joint material holds up better or worse than the aliphatic fibrous material which I put many, many tubes of chalking on over the years to try and keep anything from getting between the concrete slab and the house, but ultimately the dirt, grass, weeds, moisture, snow and ice won that battle, due to the deterioration of that joint material. Hopefully this material will hold up better over time.

Rated 5 out of 5 by from Easy to Install. Looks good With some construction adhesive , works beautifully. Make sure that it's still stuck to the concrete before glue hardens.
