Helical plates are spaced at distances much enough apart which they operate independently of each other as individual bearing factors; As a result, the capability of a certain helix with a helical pile shaft is not affected from the helix previously mentioned or under it.
The size and diameter from the shaft change according to the soil situations and helical piles supposed load. The above-ground termination could be a flat base to assist a put up or possibly a screw plate which can be linked to a foundation.
