Need advice/Uneven concrete floor
Bought a house (good price) on a slab that has a kitchen floor that is,
for some reason, very uneven. Most of the kitchen floor (the eastern two-thirds) is even but the ground under the slab must have moved after the concrete was poured because the floor has a slope to it at one end. It dips about a 1.5" - 2" at the west end of the kitchen, over a span of 6 feet (sorry I'm not metric). The house is brick outside and the brick is not cracked, nor is there sign of other damage, like to the plaster. It literally looks like they poured the slab (50 yrs ago) and that area of the slab had insufficient support underneath. Maybe the ground was not compacted properly. Anywho this floor is ridiculous. If I do floor leveler to bring it up, it will create a 1-2" step as you go thru the doorway into the dining room, which would be ridiculous as well. Previous owners just put linoleum down and probably spent decades putting things under the table legs to even it out. Questions - Can I put laminate down over such an uneven surface ? Would you level it anyway and accept the dropoff into the dining room ? TIA ! |

Questions - I would have a foundation or certified structural/civil engineer, paid by the hour and not associated with a builder, look at it, before you level it. It could be more serious than an uneven floor. Check to see that surfaces around it, like the ceiling over it, has the same slope. If so, that area of the house has settled and tilted, and may better be addressed by foundation or floor leveling. If that area of the house has settled, then down the road when you want to correct it, right up to the rafters, the "levelled" floor will be pitched yet again so it is crooked. |

Good points roger. This might be a good candidate for mud jacking the
low area, but it takes a specialist in inside work. |

If it is only the floor that is unlevel then I don't see any method of
raising the low end that won't leave some sort of step into your dining room. There are certainly ways of dealing with a small step like sculpting the threshold between the rooms so that the slope exists over a more manageable area It might be possible to grind the high side of the floor down to the level you want but it sounds like a noisy messy proposition. Maybe you only need to grind out the middle of the floor and leave the floor under the cabnets and appliances alone, this way the step will be at the edges of the cabnets where it can be hidden. wrote in message oups.com...

This is commonly caused by pouring a concrete floor without stripping the
organic material first...the stuff under the slab rots out and this is the end result. Remove the slab and repour as radon gas entry and cancer is the new factor. -- Remove the obvious to reply.
