Hello, I bought a house with a concrete floor, and the floor had a crown of about 3/4 inches in the middle of the living room. Wanting to put down Pergo, I cut out a patch roughly 10 by 10 feet and repoured the area, using the surrounding remaining concrete (about 2 feet all the way around) as a guide for the screed. All started out well… Here’s the problem — the concrete closest to the outside of the house (2 feet from the patch to the outside of the house) is now 1/4 inch lower than the patch. I hadn’t put rebar “pegs into the original concrete, and my only guess is that the expansive clay that this all sits on had been expanded when I poured the patch (April, in Northern California), and now has shrunk and sank as it has dried. I’ve given up on the idea of Pergo for the area — now I’m just looking for enough stability so that the carpet that goes over the area will not be higher some months of the year than others. Can I break out the corners, drill into both the patch and the original concrete in order to put rebar in there now, or is that just a waste of time and rebar? The opposite end of the patch seems to be holding steady with the surrounding concrete. I’m not looking for pretty at this point — just functional. Any help will be greatly appreciated. Thanks, Two Sheds |
