How to fix unlevel floors?

[Jaepheth]

Customer to Home Depot associate: "I need to buy epoxy."

Associate: "Sure. How much do you need."

Customer: "I need to make an epoxy flood... AnandTech recommended it."

Associate, *confused look* "Who is AnandTech?"

Customer: "Quit asking so many damn questions. I need your biggest bag of epoxy, ASAP!!!"

Home depot may not carry it; it's mostly an industrial application of epoxy:

Though if the floor is very uneven you may want to fill with some concrete before putting an epoxy top layer to keep costs down.

quite brilliant, I must say.

:thumbsup:

I think they actually DO do something like this in some industrial commercial application. I was in a theatre multiplex where the bathroom floors were leveled with something like this.

Might get pricey

This would be ill advised in a house, as you cannot control the lift or where the pressurised grout is going under the slab.

I had Ramjack do my cracked foundation. 15 pillars between 25 and 50 feet deep under the slab @ 950 dollars each. It was expensive but it is now level flat and stable.

Yeah I think it is more for huge slabs underneath commercial spaces, but given the OP, it was more of a joke knowing he is not going to get past the "make a thread in OT" phase of the project.

That and usually outside slabs such as sidewalks, driveways and patios. It is also called mud jacking. In a house you want a more controlled lift as mud jacking could cause much greater problems with the structural integrity of the house frame.

25 and 50 feet deep?!?!?!

Yes. They use a sectional pillar with a 10 inch arbor on the end and they screw it into the ground with a hydraulic motor adding 5 foot sections as it goes in. They screw it in until they reach bedrock or a firm base equal to 4000 psi of back pressure on the hydraulics. It is impressive. After the pillars are set they attach the jacking brackets and hydraulic jacks, and then jack each up until the foundation is level and back where it should be. Lock them down and fill in the holes etc...

I had 1 go 50 ft, 4 went down 35 ft, the remaining 10 were all 25 ft.

There is a simple and inexpensive solution to your problem and you did the right thing by asking us here.
You first run a string form corner to corner and find the lowest spot and the highest spot.
Measure the difference which is typically 1 to 2 inches in normal homes but could be more in older homes.
You go to the eye doctor and get a pair the same thickness as the difference and the floor will be extremely level and flat.

Any ideas? I'm starting to think unlevel floors might actually make it impossible to have furniture that I want to get sit flush against the ground.

Ground is easy to level; Pick, shovel and some fill.

Silly me, of course!

It's the only way to be sure.

Okay, the girl still looks somewhat promising, and I still don't know if the glasses are real.

Not sure if serious. He means the floors will be level if you tilt your head.
