Over-excavation

Got a soils report saying we need to "over-excavate 3 ft." and add compacted fill. (expansive native soil).
What does it mean to 'over-excavate'? It looks like it means in the horizontal direction, not vertically?

Alright, I'll help you out here. You are right, it means over excavate horizontally by 3'. But then you need to "add compacted fill" horizontally. For this you will need a horizontal tamper and gravity sensitive expansive native soil. This will give you the required horizontal structural integrity required.

Best of luck

Anytime for my architect friends!

Soils are level 3 of an Arch's education right?

Re: Over-excavation

A monkey could understand that over excavating means "digging more then needed" Make sure you wear you helmet.

Re: Over-excavation

Horizontal tampers are hard to find and very expensive. I suggest you go to Home Depot and rent one.

I take issue with this. He would need the gravity insensitive variety of expansive soil. The insensitive variety will compact much better.

An experienced contractor such as yourself overlooking such a simple thing, for shame.

Not to be rude, but what the F... are you talking about.

Overexcavate means go deeper, not wider.

Horizontal tamper? all compaction is done by compressing DOWN. Best if done by driving a track loader over it at optimal moisture content. Must be compacted to 90% density of surrounding natural soil. Easy test is to put all your weight on a #4 rebar. You shouldn't be able to push it in more than about 4 inches.

Compact with expansive soil?

Oh I get it! you want the guys house to fall down. Tragedy plus time equals comedy!
