For stabilizing lightweight structures such as porches, decks, or garages, helical piers are generally the more cost-effective option. This is due to several factors related to their design and installation:
- Lower Material Costs: Helical piers consist of steel shafts and helix plates, which typically fall into a mid-range material tier. In contrast, push piers require heavy-wall steel pipes and complex brackets, which occupy a higher price point.
- Reduced Labor Complexity: Helical piers are screwed into the ground using rotary equipment. This process is faster and less disruptive, leading to lower labor expenses compared to the extensive setup and skilled crew hours required for push pier systems.
- Ideal Load Capacity: While push piers are designed for heavy-duty, multi-story buildings, helical piers offer an excellent load capacity specifically suited for lighter structures and additions.
- Equipment and Access: Helical piers use compact equipment that is ideal for tight spaces and generates minimal soil disturbance. Push piers often require heavier machinery and higher daily rental rates.
In terms of specific pricing, helical piers typically range from $1,500 to $3,000 per pier, whereas push pier systems generally cost between $2,000 and $4,000 per pier.
