ALSO "Watch & Learn" ™👀 🔃 Concrete slab settlement 🔃 from Improper backfill at driveway, sidewalk & garage slab /watch/EKDY4zYHQSZHY #missingfooting ADDITIONAL INFORMATION: Concrete Settlement and Improper Backfill In the construction trades there is a term used that is called backfill. Backfill is soil that is applied against the exterior of foundations. It is one of the last stages of construction. When the builder digs out the ground for a foundation to be installed, it’s actually a wider area than the foundation, allowing the builder to set up & breakdown the concrete forms. Once the foundation is complete and the concrete forms have been removed the builder continues building and framing in the house then once completed the open area in the ground around the outside of the foundation gets filled with what is called “backfill”. Backfill material may contain many types of soil depending on the builder, location & the year it was built. Some backfill such as sand is brought in from other locations because the existing soil may not be good for drainage and compacting on homes built in areas with clay and high water tables. Sand is the most preferable for drainage and compacting purposes and clay is not good because it can retain water causing long term damage to foundations. If the builder does not compact the backfill soil properly by using high volumes of water or vibrating machines, settlement will typically start to occur within 5-10 years after construction. Due to the lack of compacting of soil it starts to sink towards the foundation effecting outer surrounding structures such as sidewalks, patios, porches, air condenser pads & garage slabs. Fortunately there are methods that concrete companies use known as concrete lifting. They simply drill large holes into the slab and affected settlement areas and pump concrete into the underside of the settled area forcing it upward into its original position which is half the cost of busting out the concrete and re-pouring. #construction #realestate #home #maintenance #inspection #realestateagentlife #craftsman #concrete #structure © Copyright 1999 - 2023 John Frejeris

That space looks to be about 24’ wide assuming it is 8’ tall like most homes.
You can also tell because they added a spanned TJI for the duct chase. The other TJI are attached to it instead of being supported by that wall.
That wall was added later to split up a basement or something and has nothing to do with bearing a load.
If that isn’t obvious to you, you shouldn’t be inspecting homes. If you failed someone on a purchase or sale inspection they should sue you.
Edit: wanted to add, cracks due to overloading slabs cause deflection. There is no deflection in that slab. How could that wall have caused the slab to crack without causing any sinking in the joint 4” away?
So the “load bearing” wall has enough weight to crack the slab but not enough to push it down any?
Without any signs of deflection those cracks are meaningless.
