That appears to be a pretty low ceiling. Is that a basement meant to be finished some day?

Yes… they poured our walls too short.. add it to the list of complaints

A new concrete floor can be overlaid as long as it's at least two inches thick. But your ceiling height may already fail to meet Code for a finished basement.

I poured one foundation wall too short--the surveyor gave us the wrong cut. The cure was to simply add two courses of block on top of the poured wall.

We dont have codes and the house has already been put on top of it. our stairs, furnace & water heater have already been set on basement floor too

Where is this house being built were there are no building codes?

Is this a custom build?

Is there an architect involved?

In the country.. yeehaw. custom build, we used a plan off e plans

Expensive, but can you dig down deeper to bring the ceiling to correct height?

If you really need to use the space I'd do what modpod suggests. It will require a competent contractor (ie not the one who did this work) to dig out and reinforce the footings from inside then excav\ate and drop the floor by about 2 ft. to give you clearance and a flat floor. Not at all a cheap fix, nor without risk. Much cheaper and easier to add space above ground either as an addition or outbuilding for whatever you were going to do in the basement.

What height basement is shown on the drawings?

What height basement was built?

but can you dig down deeper to bring the ceiling to correct height?

AS mentioned above, you can underpin the existing foundation. Or you can excavate down and build a buttressing wall around the interior of the existing foundation.

I've done the latter on a 100 year old home per a structural engineer's evaluation and drawings.

But as mentioned above, likely no more costly to add above-ground space for what you need.

The support posts look crooked, too. What a mess. Hope the ground floor is coming along better...

Our posts are perfectky straight, just went to double check. it may just look that way sur to poor photo quality or because they came back to sand the floor to be more level.. which actually just scratched it up & made it worse. were more concerned with just having the floor be level vs the height of the walls.. we dont ”need” space its just more of a bonus

When some of these concrete guys gonna learn that you are supposed to drink beer/wine after the job, not on the job...

But I don't think this was a concrete crew doing this pour because even a drunken crew would have done a better job... It looks like a builder picked up a bunch of guys in the parking lot someplace, dumped 10 yards of concrete in the basement, and told them to jump in and make it look pretty... I see this type of scenario's all the time around here.

I don't know what they were thinking about leaving it like this...

If this wasn't done by a "parking lot crew and your builder has some concern for his reputation or you as his customers and this was done by a licensed contractor (which I doubt) who totally screwed this up... He will not pay him and make him repair the floor. Not to mention he knows that you can't put any type of flooring down if you going to finish your basement in the future.

That said, it looks like the portion of the floor further back looks more level (unless it only looks that way in the picture) I would make him cut and remove the bad section and re-pour and get it done right.

Good luck

I didnt know you could cut portions of flooring out?! & we have already banned the original crew from coming back which makes things harder because apparently people dont like to work over someone elses mistakes..

Yes, make sure they do dry cutting using a concrete saw with a dust attachment shroud connected to a vacuum, makes a nice clean job especially when you are inside of the existing home.

Don't let them use wet cutting, you will have a mud pit down there.
