How to fix a poorly poured concrete floor?
I am looking to buy a new house soon, and like all of the houses where I live (apartments and free standing house structures) the house is a mess of poured concrete from the floors to the walls to the ceiling.

The problem is that most of the houses I have looked at the floors have laid exposed and untreated for so long they look like they have water damage, and the pouring is just horrible. But the cost of going with a finished house where all these problems are hidden away is double the cost of the unfinished house.

So is there away to fix the floors so that they are smooth and level with out a jackhammer and construction crew?
I took these photos while I was looking at the last place, 1 year after the house was completed.

Concrete is seldom used as the final finished floor--Consider using ceramic tile over the top.

True, I do plan to put bamboo flooring as the finisher.
However, the look of the concrete is not the main issue, the main issue is that is is so poorly poured that it looks like your walking through a gravel pit, thats why I am asking this question. Since I have not seen a house with decent flooring put in where the cement slab was so ruff and uneven.

Where I am living now, due to my job I have to live in X community and since all the houses were built by the same construction crews they have the same problems, and before I throw down 100-200 grand to buy a house I want to make sure that its going to not cost me a fortune after when I start the interior work. And I am sure reflooring a poured cement house will cost a fortune, especially if its the upper 2 floors of the house in multiple rooms that require reflooring.

I did not see you location when I posted my response----I've seen some truly awful finishing jobs in my travels---You may need to contact a local cement man to see what your options are---

and what products the locals can successfully use.---I have seen concrete floors that have major voids,rake marks and even foot prints.

Post some pictures if you have any---Good luck---Mike---

So my pictures still don't show up...?
Sorry I just opened the account so I didn't get around to adding the detailed info until after I saw the first reply.

Ok, yea the finish job is terrible and the house I want is by far the best.
So, this sounds horrible and please don't judge me too harsh because its a joke, but I told my coworker that I should import a few mexican to teach how to lay cement and to get a proper job done. :laughing: sorry if this was offensive:sweatdrop:

These were taken with my camera phone, so they are not super resolution or anything, but you can see why I am asking fixing the floor.

I just saw the pictures--Yuck---Import those Mexican finishers!

Actually--You can have tile set over that mess and have it turn out very nicely.

That is one sloppy looking floor--but ceramic or stone could hide that ----Mike----

I live a long way from Mexico--but I have enjoyed many weeks in that wonderful country.
Fine people there---I wish them well with their current political and crime issues.--Mike---

I had to google--Guangzhou---That's close to Hong Kong and Macau---This is an international DIY site.

Some times our advice must sound pretty funny----Mike---

As poorly done as those floors appear to be...Like Mike says tile is still do-able and I would think so is bamboo. I'm wondering if you could rent a floor grinder locally and smooth out the floors in that manner.:) Grind the serious high spots then fill the low spots.:yes:

I have seen floor challenges like this where they have had the floors themselves ground off by about 1/2 of an inch to expose the character of the concrete and it looked superb, just a thought....

I agree. That, plus a good subfloor should make for a great-looking space.

I know that for concrete floors that have been damaged by foundation settlement, some contractors will clean the floor, ground down the mess, and pour a new concrete floor surface on top. That technique doesn't work well for settling floor slabs because future settlement of the floor causes new damage, but the concept would work perfectly for leveling a concrete floor like the one you speak of.

Here's a video on it:

Those floors look like there may have be some bad weather immediately after pouring, plus the local traditions in your area are marble ot tile, so the concrete surface appearance is not that important. All the floors are probably poured in place concrete or possibly are precast concrete that is topped.

One way to check the general quality of the floors is to check the quality in the "wet" rooms (baths and possibly the kitchen) where they have sloped floors for floor drains.

I was in Guangzhou several times and the first time I assumed it was a small place. After seeing it, the modern buildings and metro area, the area population of over 20,000,000 is understandable. It also very new and modern. I have heard it is second to Tokyo as a metro area. You certainly get lost with you head buried in the ground and not looking around.
