Rent the equipment or think about an overlay

Looks to me like an overlay might be your best bet. Before you do anything check the thickness and quality of the existing materials. The work looks bad enough that it makes sense to question materials quality. There is no point in doing a quality overlay on top of something that will fail soon.

Looks way to f ---d up to grind IMO. Assuming the concrete is thick enough and of proper quality, i would be considering an overlay... G

just imagine that it's your site, your budget is limited but you need to make it as a normal parking area

what you gonna do ?? what are any other options rather then grinding ?? what is the most reasonable way ??

Looks like they poured wet and piddled it with 2x4. Looking closer at the photos around the edges there is alot of crete just sticking up. If I was going to fix this I would probably cap that mess if posible. By the time you profile, , grind edges, and clean the area it may just be all for nothing because the floor itself looks all over the place. Do the pitches work now?

You may have to remove some of the area near the exterior door to get a good thickness. Use wire reinforcement, fiber and readymix concrete with a polymer you can add into the truck before you pour. Again I cant see the whole area to be definitive. An overlay may work on the cosmetics, but it will just mimic the pitches you have now.

what about polymer modified overlay ? wil it works ? does need any floor preparation ?

Hoven

The polymer is what gives the material it bonding properties. Overlays tend to fail at thicknesses over and inch or so. I haven't found one yet that can make up say 2 inches and feather to almost zero . If anyone does know of one let me in on that secret please. They are designed to work thin. So areas that are real low may require additional applications to make this floor appear some what flat. I still think a cap is the way to go if possible. Get a transit take some readings and see what your working with first.

what about this ?? will it works ?

Please advise

That milling head will leave about the roughest floor possible. They are used for removing a large amount of material in one pass. Think of a road resurfacing project where the entire top layer of road is removed. Very rough afterwards.

I would jack hammer it out and start over. Concrete grinding is no fun and you have A LOT to do. Don't throw good money after bad.

Hoven

Like i said before cap it and jack out what you need to near the exterior doors.

How in the world did that happen? Thats not a job for a first timer! Did the company not own a mag screed or even a bullfloat? No one even attempted to finish that! Tear out and repour!
