House Slab - Cracks
House Slab - Cracks
(OP)
Hi all
We are building a new house and I work away for long periods. This trip home I noticed a crack in the kitchen area that to me looks quite alarming.
Crack is about 1mm wide and runs for approx 4 meters from the fridge recess to the external doorway.
Cannot tell if the crack is stable or still growing.
We plan to install large 900 x 600 tiles through this area and I am worried that they will crack down the track if the concrete continues to move.
Has anyone had any experiences with house cracks before.
Should I be concerned
Builder says that these are settling cracks. Easy answer from them.
First post so I hope the photos attached OK
Thanks

You could monitor it, but that will delay completion. You might want to hire a structural engineer.

Not uncommon in residential construction. We need a bit more information about the orientation of the crack and perhaps a sketch of the area, including the crack, and the surrounding concrete slab features.
There are several ways to mitigate such a crack, even when installing tile above. Please provide more information/sketches/photos so that perhaps we can help.

I am intrigued, what are the visual indications that a crack occurred while the concrete was plastic?

Per the original post- Cracks will translate through the tile unless it is stable and has been properly prepared for a new surface on top

How long since the concrete was poured and how was the slab reinforced?
