If you're worried about driving over it, lay a couple boards down to protect it. Once you're done, sprinkle more sand over the top so that no one steps in it and tracks it into the house. The joint will look better if you fill it slowly and let it flow out before adding more, and don't get it too full. maybe filling it halfway, then when you get to the end come back and fill it the rest of the way. If there are any cracks or dips anywhere in between you will want to block these with sand because the sealant will run out of the crack and make a giant mess.Īpply just a little at first. You want the self levelling sealant to be no more than 3/8" thick.īlock the ends by driving a stake tightly onto each end. Take a thin board (such as 1/2" plywood scrap) and tamp the sand down. Clean the gap out so that its clean, then pour some clean silica sand (you can buy bags of this where bag cement is sold) into the joint until you are about 3/8" from the top. Look for PL Polyurethane S20 Self Levelling sealant.
Sealing gap between garage floor and wall how to#
To note from thje pic, the previous owner had some of that black stuff (tar?) in that area but, since it has crumbled.Īlso, there are small pot holes in the driveway as can be seen in the pic, if anyone has any ideas on how to fill those as well, that would be useful.Īs mentioned, they make a sealant for this. I have thought of dropping some pea gravel down there to help with the water absorption or sand for that matter? I also am curious to is there a special caulk or filler I can buy to make this easy? I live in the midwest in IL, so we'll see freezing temps to the heat extremes. I want to know from those who have dealt with something similar what is the best approach? My concern is water getting down there and causing issues that could lead to the concrete slab sinking again. It has improved the gap in terms of height however, there is quite an opening in between the concrete slab and the garage. We just recently had our driveway mud-jacked. Hello, first time home owner who has been getting into the diy work.
