We have noticed over the last few years that there seems to be a crack in the concrete slab under our breakfast area. What we are seeing is a warp in the linoleum/vinyl floor that cuts off a corner of the room at the corner of the house. We are looking at replacing the downstairs flooring (vinyl flooring in the kitchen/breakfast area and carpet in the rest of the downstairs). I do not know how "bad" the crack is (i.e. how deep or wide it is) as it has flooring glued to it. Before we put anything new down, I know we should address the crack. How that should be addressed, I do not know as I do not know how bad it is. I feel like I should consult a professional to assess the slab issues. We are in southern Louisiana and we do get lots of water. Our home and yard have not flooded.

I am concerned that if I call a foundation person, they may have a tendency to look at all cracks as a serious foundation issue but I would not know who else to consult. Any options/ideas/recommendations/suggestions?

The main rule of a large slab or concrete(over 10') is, it will crack. There are usually control joints to tell it where to crack. Wether it is a major problem depends on if it grows(gets wider) or shifts vertically. There are membranes that can be laid over a crack to minimize its' affect.

Hello,

Am about to complete on a new build home. However, on inspecting the new property throroughly for the first time, there appears to be large cracks running accross the concrete floor. The developer tells me that these are superficial and not stuctural. How can I be sure and how am I protected?

Surely, an NHBC cannot be issued should there be structural defects?

Rather than a contractors word and admitting failure you will need a engineer that specializes in building material for a true answer .

Slab cracks is not big deal. Slab cracks in 90% of the houses. It’s not foundation and it’s not structural.
You can calk with any silicone calking. There is plastic under slab. Slab does not stop water and if you have flooding underneath then it doesn’t matter if you have crack or not water will come out anyway.
