Question

Concrete basement floor.


I'm adding a basement bathroom (close to the main drain) to a 50yr old home. I have most of the trench dug for the shower drain, but I've come to a point where the concrete floor changes from being 3 or 4 inches thick to 12" thick!! The area in question is 3' from an outside wall and 6" from the main drain which I've already exposed.

Any thoughts on why this might be? Will I be compromising structure if I bust it up?

Thanks in advance.

Probably part of a footing. I doubt you'd want to "bust it up" without consulting an engineer first.

Hard to say. It is not uncommon for slabs to be thickened and extra reinforcement is added as an approach to adding some bearing/structure to the slab due to various reasons. Normally there would be a wall running on a thickened portion of a slab, but not always. It is equally likely that they just had extra concrete when they poured the slab.

Only way to know for sure is to have an engineer take a look at it.

some times an area taht does not compact well will have bad fill removed and concrete vs gravel will be used over the bad area. sometimes a stump will be found during excavation
