Friction coefficient between soil and polythene covered concrete

Friction coefficient between soil and polythene covered concrete

Hi Good Day everybody
Can anyone give me some guidance about Friction coefficient between soil and polythene covered concrete footing?
thanks

RE: Friction coefficient between soil and polythene covered concrete

My experience is the value is near zero.

I once had a load of prepared sand on my trailer for ice removal purposes when I lived in the country. Since it was salty sand, I first put a sheet of plastic on trailer. In going home I went up a road at about 10 degrees slope. Then I turned onto a side road at no more than 20 degrees lope, probably 15. Getting home I was much amazed to see the trailer empty. Going back there was a neat pile of sand on the plastic in the middle of the road at the steeper slope. I suggest you do a similar test.

RE: Friction coefficient between soil and polythene covered concrete

OG, very nice example. I also consider the value to be zero. For example, if we have a plastic moisture barrier sheet underneath the floor slab, I recommended no consider contribution of lateral resistant from the slab friction with the soils.

To which I'll ask, what's the end game? I mean If I was some researcher and claimed to know the answer was 8 degrees, what would you then do with the number?
