Slip Zone Around Steel Piles to Reduce Frost Heaving
Slip Zone Around Steel Piles to Reduce Frost Heaving
(OP)
We are having issues with frost heaving driving steel piles out of the ground for a pipe rack. We are replacing most of the piles with screw piles which seem to perform better, but there are a few that are inaccessible and can't be replaced. Does anyone have any information on the concept of creating a "slip zone" around the steel piles to reduce the heaving? I don't have any information on how this is done, or the effectiveness of it. Someone just mentioned this to me as a possibility to explore.
Thanks.
Thanks.

A simple method commonly used with adfreeze (freezeback) piling is to wrap the portion of piles within the active layer (freeze/thaw zone) with 3 or so layers of polyethylene, tape securely.

If piles are truly inaccessible, methods to prevent frost jacking/heaving are limited.
Only thing that comes to mind is to place a shallow insulating layer to reduce frost penetration.
