Level Tolerances in Concrete Construction
Level Tolerances in Concrete Construction
(OP)
Hello,
I'm going out of my area of expertise but I'd like some help from the Structural group. I am buying a new (concrete) apartment and the floor is slightly bumpy in different regions in the main family/dining room. The contractor mentions that the concrete building code suggests that such a difficiency within 1/4" is tolerable by the Concrete Construction code. While doing some extra research I stumbled upon an American document that never stated any reasonable tolerances, but had solutions to keep it flat/level. Does anyone know if such tolerances exist? If so, what are they?

I don't recall which ACI publication addresses this.
For residential construction, the tolerances are going to be less unless specifically spelled out during construction.
The low spots can be leveled out with different concrete products. It will depend on the size of the low spot and the depth to fill as to which prodect and/or repair procedure is used.

Or get an allowance from seller to fix the floor yourself.
If you were installing tile, the concrete bumps may not be a serious fault as I think grout could account for this. Possibly wood flooring could cover this as well.
This situation is common in European countries like Ukraine. They cover floor with some type of wood and this was acceptable for them.

The disturbing part is this is a luxury style condo that was expensive, so I'm going to pursue this further!
The fact that the contractor even acknowledged the problem existed makes me wonder if they were hoping the laminate flooring that was placed on top of it would hide the defficiency. Upon visual inspection its difficult to tell, but once walking upon it it's easily noticeable.
Thanks for your responses, I'll dig deeper with the developer!

Do you know what the typical tolerance for residential construction would be? I don't have open access to those standards.
