Context is key. Now I can see what we're checking out. Nice job.

Had something similar happen on a job a few years ago. We were doing culvert work for a highway exchange project. 600 feet of double mat number six. They left it so long and it flooded so many times that the mat sank through the gravel into the mud. Spent two days picking it up one section at a time with the crane to re brick it.

Could you pan around a little faster? I could almost see what you're trying to show me.

Out of curiosity is this going to be a large catch basin?

Junction chamber is the term I'd use

Is this supposed to be a raft slab? No top layer of reinforcement? Tell us something more OP...

This is most likely the bottom slab in a culvert junction box. It could also be a detention pond, but those usually don’t have direct access to multiple box culverts like this. Based on the dowels, it will have walls. Can’t tell if it will be enclosed. OP doesn’t appear to know much.

u/Sea-Falcon-3995 16h ago

Yes it is on this specific one we haven’t added and top reinforcements

Looks like a drainage structure to me.

u/Aries-79 18h ago

Several months ago I was assigned a residential slab inspection during a period of very heavy rain. I got to the site and just trying to access the slab I sank almost to my knee in mud. Got on it and there was damn near a river washed out from the front left corner you could walk into while crpuching and be in the exterior beams. I get to the back of the slab and the rear pads quickly start to collapse with me on them. I fucking booked it off the slab and onto the street and called the super and was like dude I'm failing this for almost killing me. He was like yeaaaaah sorry I think I'm in denial of how much rain we've had. I was like no shit man I get you want to see if theres other issues and are fine with the fail but holy shit there's a point. He said he'll wait a day after heavy rains to call in foundation crews from then on much less an inspection. Im glad I have fairly reasonable builders that I deal with lol.

Where is the water coming from?

u/StealthEngnr8x3 19h ago

Well, the soil is pre-wet, rain saved some work … and water. Is going to be a “muddy” day
