How deep do you dig a footing?
Depth of Footings Footings should extend to a minimum depth of 12 inches below previously undisturbed soil. Footings also must extend at least 12 inches below the frost linefrost lineThe frost line—also known as frost depth or freezing depth—is most commonly the depth to which the groundwater in soil is expected to freeze. The frost depth depends on the climatic conditions of an area, the heat transfer properties of the soil and adjacent materials, and on nearby heat sources.https://en.wikipedia.org › wiki › Frost_lineFrost line - Wikipedia (the depth to which the ground freezes in winter) or must be frost-protected.Jan 12, 2021

How much do helical piles cost to install?
The cost of a helical pier depends on the design, size, and weight of the structure and the adjacent soil conditions. Due to these many variables, an installed helical pier can range in price from $15-$30 per foot. So, a typical 20-foot helical pier can cost between $300 – $600 each.
