Digging out basement


Hello DIYers,

I'm looking for some technical help on supporting a bench ledge as I will be digging out the basement.

I want to go the easier route (as opposed to underpinning). So far my test holes have shown that there is three feet of sand underneath, nice for digging but worrisome as a support material.

Rebar and concrete ledge? How is it anchored?

Thanks in advance

Drawings of what you have and what you want to do are always helpful. You may or may not get anyone to advise on something this risky w/out being able to touchy/feely.

Digging out basement


Are we to understand that you are digging out a basement on an existing house? While the house is in place?

Oh boy....I'm a big DIY guy but this has red flags all over it....as well as Darwin's name...

Digging out basement


We've done this -
Dig out a crawl-space to make it a basement.
(Or, extend the depth of the basement, to acquire more headroom.)

I'm not sure that this is a "DIY" project.

As stated above - better find somebody who has experience/expertise
doing this - "eyeballs" on site!

No "underpinning" - no "needling" -
Get a "Structural Engineer" to look at it!!
Have you ever seen the ramifications, of a basement wall that fell?
I have!
What's that saying - "penny wise - dollar foolish"!
And, you're on sand!!

"Joe Carola"
You don't have to be so harsh! - so judge-mental! -
It's the "Happy", Holiday season!
Jeesh!
Everything is so "serious"!
What's the worst that can happen??!!

(My house fell over!!)

I think the person should wait until a "Tornado", "Hurricane", "Cyclone", "Tsunami" hits and moves
the house out of the way.
Put in a new foundation - wait for another "Act of God" (Or - the "Diety" of your choice) comes back; and, moves the house back onto the foundation -
(Ahhh - "Nature" - the "ultimate" "DIY'er!!)
"Permits"?? - we don't need no "stinkin'" permits!!!

I don't know what a "bench ledge" is, so I googled it. I found at least a dozen definitions, one for women's sweater, one for an open pit mining operation, one for urban skateboarding,. one for a bathtub seat. You get the picture, I have no idea exactly what you are planning to do. I will be happy to discuss possible means and methods with you if you will describe in detail the existing condition of your property, exactly what it is you wish to accomplish, and the methodology you are thinking about using.

I know what a "bench ledge" is - old term.
In this person's situation -
without proper and careful "shoring" - (driving bunches of stakes into the
soil/substrate, is not going to be enough - sand!?!)
Permits- inspections? - doesn't sound like it!
Remember - you can lead a horse to water: but, you can't make them drink!

Happy Holidays!

I don't think this is a "DIY" project!
Just my opinion.

Digging out basement


"Bench-ledge"
You dig down away from the footings - how far back, depends on the soil
conditions.

You put something in to hold up the soil/footings/foundation from
collapsing.
Forms, shoring, etc ...

Then, you address the problem from there.
No, don't dig out one side, completely.
Sand - that's going to be fun!

You try to create a bench-ledge.

rossfingal

I don't know why someone didn't, just "chime-in" and tell the "OP" -
Structural Engineer"!!

Someone did 4th post.
To the OP- we might sound a bit mocking but especially since you pointed out the sand. All I can add is please post progress pics. I don't want to miss a thing.
