I havnt done that, but I have jacked up the garage and had a company re-pour the floor. It turned out really nice. any concrete company will form and pour it.
yes, I broke up the floor first with a sledge hammer. Then had a new 4" thick slab poured. We also had to put in a new approach to the garage because it was 4" higher than the driveway. It worked well, and is still standing.
our garage had the same problems. We didnt want to build a new one, because it required new building permit, and the garage was too close to the neighbors garage/property line or something like that, so we decided to just fix the floor and some of the bottom boards. We didnt want to just lift the garage floor because the old floor was all crappy and cracked.
It sounds like it is built on a slab, maybe.
Do you know if it has a frost wall and footer?
If you pour a new floor it will probably do the same thing.
I’m sure it is just a slab.
I doubt they did anything special back in the 50’s.
A new floor would have to be above grade, and ideally place the sill above the floor and have some sort of curve next to it so that water would draing away.
I should add that tree roots were growing under the garage causing the floor to crack originally. we also had the tree cut down in the back yard before fixing the garage floor.
You said it has big cracks so mud jacking probably isn’t a good idea. You generally would do that when the concrete is in really good shape but just not level.
I had several slabs of my patio and driveway done and was really impressd with the result and cost savings vs breaking up and pouring new. But, my concrete was in perfect condition, just shifted.
Yea, there are some large cracks. The concrete in my garage is by far the best of my property. My whole driveway is a cracked mess. The winters are not kind to it at all.
If I can get something that will work for a few years I would be OK with that. It all depends on the cost vs. a new pour. I’ll have to investigate both. It might be affordable for new pour if I can dig it up myself.
(most likely, I’ll put it off for another year or two and just keep complaining about it :()
anyinfo yet about “mud jacker” … I need to bring something up about a inch but there is about 10+ tons of brick on it!! … my chimney(fire place) is on said slab and it cracked …
