how to level a concrete slab.?

Rough it in with concrete on the half you need to bring up in order to then use the (up to 1 inch ) leveling product atop the entire surface. It's really all that's needed with no long explanation required.

Make sure to use the "smooth-semi smooth" concrete and finish with a "Smooth" top coat leveler.

You should also etch the surface between ALL coats to ensure adhesion.

Other than that, you're all set. An extremely easy beginner project with minimal experience required.

i find all that's needed for many home projects is the desire to get started and ability to read directions and review a few DIY videos widely available for free viewing on-line.

From the information gathered from your question you appear as though you'd have no problems figuring out what's needed as you go.

I find many deteriorating factors (Crumbling, chipping, flaking) can be traced back to the concrete and leveler not being mixed appropriately. Get your mixes right and that's half the battle regarding durability.

An alternative would be to jack hammer down and remove enough so you could pour a 4"- 6" top coat slab atop what's left after removing the top surface.

If it were me, I would opt for leveling it as I indicated at the beginning and be done with it.

Your best bet is to jackhammer the existing slab out, and pour in a new one. Bearing walls need a foundation, so you have to pour concrete anyway...

A slab poured on top of another slab is destined to fail.

It seems that this project is beyond your skill level. Get some bids from contractors.

PS. Have you looked into the cost of self leveling concrete? A 50 lb bag is $30, which only covers 0.50 cubic feet. You have 190 square feet to level, at an average of 2" thick. That's 15 cubic feet. You'll need at least a pallet of it delivered to the job. Do it right. Replace the slab.

And is there an elevation change between the patio and the house? You may be able to pour a foundation, and run a wood joist floor above the existing patio. Lots of factors to consider, and only experienced eyes looking at the job can determine the best course of action.

Hello ERIC .... please get some bids for the leveling and the tile work -- a good tile man will be able to help you have a professional look to the completed new den or family room [f-r] == since you are asking this Q. it is apparent that you need the help and want your f-r to be nice when done .... those bids will help you decide which way to go for end results == maybe get the tile man to level it for now then do the wall studs and string wires and put in the wall and ceiling boxes == get it dryed-in and do the rooF as it is much easier to work in the shade==== either panel or do sheetrock and make a good fire-base and back for your wood stove or fireplace == about now you are ready to pick tile and get the tile setter going === the last thing you do is the tile floor [[[[ what if you drop your hammer on you new tile -- thatz ah reel prob -- enjoy the new f-r ..... exterior material can be brick or the T-one/eleven exterior panels - either will look good ....

Get some self-leveling mix, it is very effective and easy to use.

Ask the guy at the store about its use.
