How To Mitigate The Risk Of Frost Upheaval?

Earth Anchor mounting system can mitigate the risk of frost upheaval. Frost upheaval occurs moisture in the soil freezes and expands. This expansion tends to push against large surfaces like concrete or steel posts. The unique quality of the Earth Anchor which has proven itself time and time again is that there is virtually no surface within the frost column for the frost to push against thus eliminated the fear that frost will somehow pull the anchor out of the stable ground below.

In regions where the frost depth is 48" below the surface Century Metal provides an anchor that gets driven to 5' below the surface. This allows for the anchor to be embed into soil which will always remain stable. Unlike large pile steel or concrete piers which have a lot of surface area for the frost to push against the Earth Anchor only provides a small stainless-steel cable. Combine that with the weight of the system pushing down from above which is roughly 200 lbs. per shoe plate, and you get a push and pull situation which is very effective in combating uplift by both wind and frost. What generally happens is the frost takes the path of least resistance and rises around the shoe plates.
