When comparing steel push piers and helical piers for your property in Centennial, you must look beyond the initial per-pier price. Several technical and environmental factors will influence the overall effectiveness and total cost of the project:
- Soil Composition and Behavior: Centennial’s expansive, bentonite-rich clay soils fluctuate with moisture. A geotechnical report is essential to determine the soil’s bearing capacity, groundwater depth, and expansion potential, which dictates how deep piers must go to reach stable strata.
- Structural Load: The weight and configuration of your home (e.g., a multi-story heavy structure vs. a single-story wood-frame addition) determine the necessary pier spacing, depth, and load capacity. Push piers are often preferred for heavier loads, while helical piers suit lighter structures.
- Site Accessibility: Access constraints on your property can dictate the method. Helical piers use more compact equipment (torque motors) and require less headroom, making them ideal for tight spaces or crawl spaces where heavy hydraulic rams for push piers cannot navigate.
- Installation Timeline and Disruption: Helical piers generally offer a faster installation and immediate load capacity. Conversely, push piers may require more extensive excavation and specialized heavy machinery, which can increase mobilization costs and site disruption.
- Engineering Requirements: The need for professional geotechnical reports, structural engineering calculations, and custom material requirements (like corrosion-resistant coatings for Colorado’s clay) are critical considerations for a long-term, permanent solution.
