How to fill GAP between house slab and sidewalk/yard??
+6
We have an ever growing/deepening gap between our house slab and the side patio and also the yard. It basically is entirely around the entire house. Is there some sort of expanding spray foam that is just for this problem? We really don't want to hire a contractor and all that.
How about filling that up with some quikrete?

Yes, there is a foam that can jack the cement walk up to the house slab where it originally was. Have it professionally done. The walk is sinking as the soil is settling and it needs to be brought back up to its original slant so water does not continue to seep under the slab of your house and walk. I did that on a slab in my carport. You can't tell that it had broken and sunk. It is not very expensive compared to having cement poured under the slab to bring it up to where it should be.
If you don't want to hire someone to jack up your concrete I would try using a fill of pebbles and polymeric sand. the pebbles would mostly fill the gap and the polymeric sand would do the rest. This would allow for expansion and contraction with temperature changes and all you need do is add more of the sand, if necessary. Caveat: do this when everything is dry because polymeric sand hardens when water is added. I used it to fill the expansion joints in my driveway to block weeds from growing in the gaps.
WE used filler foam its at home depot you spray it in and it expands and fills in what spot you want, and you just scrape it off if it comes out to far
THANKS SO MUCH TO EACH OF YOU ABOVE!
It is separating because the soil is shifting. Either due to settling or the tree roots. Just patching the separation will not fix your problem long term. It will only be a temporary solution.
