Installations with portable or vehicle mounted equipment is accomplished by means of adapters. Helical piers are round or squire, tubular or bar steel shafts with round helix plates welded to them.
Their applications include both light and heavy foundation systems for new construction, tie downs for structures subject to uplift, piers to underpin and level structures subject too settlement, and tiebacks and soil nails for the retention of slopes and structures.
