Choosing Between Concrete and Helical Piers for Your Deck

When building a deck, one of the most critical decisions is selecting the right type of foundation. The two most common options are concrete piers and helical piers. Each has its advantages and ideal use cases, so understanding the differences will help you make the best choice for your project.

Concrete Piers: The Traditional Choice

Concrete piers have been the standard for decades. This method involves digging holes below the frost line, placing a footing, and pouring concrete to create a solid support base.

Pros of Concrete Piers:

• Cost-Effective: Concrete is generally more affordable in terms of material costs.

• Widely Accepted: Most contractors and building departments are familiar with this method, making permitting and approvals straightforward.

• Strong and Durable: When properly installed, concrete piers can last for decades without requiring maintenance.

Cons of Concrete Piers:

• Labor-Intensive: Requires significant digging, forming, and pouring, which can increase installation time.

• Weather-Dependent: Concrete work must be done in suitable weather conditions to ensure proper curing.

• Soil Conditions Matter: If the soil is unstable or prone to shifting, concrete piers can settle or heave over time.

  
  

Helical Piers: A Modern Alternative

Helical piers are screw-like metal supports that are mechanically driven into the ground. They are commonly used in foundation repair but have become popular for deck construction, especially in challenging soil conditions.

Pros of Helical Piers:

• Quick Installation: No need for digging or waiting for concrete to cure; installation is typically completed in a single day.

• Works in Any Weather: Unlike concrete, helical piers can be installed year-round without weather-related delays.

• Great for Poor Soil Conditions: Ideal for areas with clay, sand, or high water tables where concrete piers may not be stable.

• Minimal Site Disruption: Requires less excavation, reducing mess and damage to surrounding landscaping.

Cons of Helical Piers:

• Higher Upfront Cost: The materials and specialized installation equipment make helical piers more expensive than concrete.

• Requires Specialized Equipment: Professional installation is necessary, adding to the overall project cost.

• Less Familiarity: Some local building departments may have additional permitting requirements due to limited familiarity with helical pier technology. An engineer stamp on the helical piers is required and provided by your helical pier installer.

  
  

Which One is Right for Your Deck?

Your choice will depend on several factors:

• Budget: If cost is a primary concern, concrete piers may be the better option.

• Soil Conditions: If you have poor soil or a high water table, helical piers are often the more reliable choice.

• Project Timeline: If you need your deck installed quickly, helical piers can save time.

• Long-Term Stability: If soil movement is a concern, helical piers provide superior stability over time.

Both options are effective and durable, but the right choice depends on your specific site conditions and priorities. Consulting with a professional can help ensure you select the best foundation for your deck project.
