For a standard home foundation stabilization project, the number of helical piers required typically depends on the specific project type and the section of the foundation being supported.
General estimates for residential projects in the Centennial and Denver areas include:
- Small Basements (under 1,000 sq ft): Usually require 4 to 6 piers to provide corner and mid-span support.
- Full Foundations (1,500–2,000 sq ft): Typically require 6 to 10 piers, depending largely on the soil’s bearing capacity.
- Additions or Sunrooms: Generally require 2 to 4 piers, as support is often focused on the perimeter.
- Retaining Walls or Decks: Often require 1 to 3 piers per load point.
- Foundation Sections: Most individual foundation sections require between 2 and 6 piers to achieve proper support.
As a preliminary budgeting guide, you can estimate roughly one pier per 250 square feet for moderate clay soil. However, the exact number is determined by a structural engineer based on the building’s total load (weight), local building codes, and soil conditions—specifically whether the site consists of stable sandy soil or expansive clay, which often requires more piers.
