Building a deck is like crafting the perfect outdoor sanctuary; a space where family gatherings, weekend BBQs, and quiet morning coffee sessions come to life. But behind the beauty of the deck lies a robust support system that ensures its stability and longevity. Enter helical piles, the unsung heroes in the world of foundation support. If you're envisioning a long-lasting and sturdy deck, helical piles should be at the top of your list. Let's dive into what makes them so special and why they're a game-changer for deck support.
What are Helical Piles?
Helical piles, also known as screw piles or helical piers, are deep foundation solutions used to support structures. Think of them as giant screws that are twisted into the ground providing a secure foundation on which to build your deck. They consist of a central steel shaft with helical plates (helixes) welded onto it. These plates allow the pile to be screwed into the soil, much like driving a screw into wood. A helical pier has either a solid square or round shaft with helical plates welded to it. The helical plates transfer the load from structure to the soil, replacing the need for concrete.
The installation process is straightforward, yet the resulting support is incredibly strong and reliable. A Chance certified installer or professional engineer should be consulted regarding the required loading of the pile. The requirements may vary depending on the jurisdiction of the project.
Why Choose Helical Piles for Decks?
Quick and Easy Installation:
Helical piles can be installed relatively quickly compared to traditional concrete footings. They don't require excavation or concrete curing time, which speeds up the construction process. This means less disruption to your property and a faster turnaround for your deck project. Small equipment, like a skid steer or mini-excavator can be used to install the pile. This allows for installation in tough access locations and limits the impact on the landscaping and lawn.
Minimal Impact on the Environment:
Unlike traditional foundations that involve significant digging and disruption, helical piles are minimally invasive. They leave a small footprint, making them an eco-friendly option. This is particularly advantageous for decks built in environmentally sensitive areas.
Superior Load-Bearing Capacity:
One of the standout features of helical piles is their exceptional load-bearing capacity. They can support heavy loads, making them ideal for large decks with roofs, extensive furniture, hot tubs, or even outdoor kitchens. The helical plates provide resistance against both compressive and tensile forces, ensuring the stability of the deck under various conditions.
Versatility and Adaptability:
Helical piles are versatile and can be used in a wide range of soil conditions, including clay, sand, and even rocky terrain (Trust me – I work for Rocky Mountain Steel Foundations!). This adaptability makes them suitable for various geographic locations and soil types. Whether you're building on a hillside or in an area with challenging soil conditions, helical piles can provide the necessary support.
Immediate Load Transfer:
Unlike concrete footings that require curing time, helical piles can be loaded immediately after installation. This means you can proceed with building your deck without waiting for days or weeks. The immediate load transfer capability of helical piles is a significant advantage for projects with tight timelines.
Cost-Effectiveness:
While the upfront cost of helical piles may be slightly higher than traditional footings, the long-term benefits outweigh the initial investment. The reduced installation time, minimal site disruption, and durability of helical piles can lead to overall cost savings in the long run.

How are Helical Piles Installed?
The installation process of helical piles is precise and efficient. Here's a step-by-step overview:
-
Site Assessment:
-
A Chance certified installer or Professional engineer assesses the soil conditions and determines the appropriate helical pile specifications for your deck project.

-
Helical Pile Selection:
- Based on the assessment, the suitable helical pile type, diameter, and length is selected. This ensures that the piles can reach the required depth and provide optimal support.
-
Installation:
Using hydraulic equipment, the helical piles are screwed into the ground until they reach the desired depth. The torque applied during installation is monitored to ensure the piles achieve the necessary load-bearing capacity in stable soil.
-
Load Testing:
Once the piles are installed, load testing may be conducted to verify their capacity and stability. This step verifies that the piles can support the intended load of the deck.
-
Deck Construction:
With the helical piles in place, the deck construction can proceed. The piles serve as a robust foundation, providing a stable base for the deck's framing and surface materials.

Conclusion
In the world of deck construction, helical piles are a game-changer. Their quick installation, environmental benefits, superior load-bearing capacity, and adaptability make them an excellent choice for supporting decks. Whether you're building a small backyard deck or a large outdoor living space, helical piles offer a reliable foundation that ensures your deck's longevity and stability. So, the next time you plan a deck project, consider the superpowers of helical piles – they might just be the unsung heroes your deck needs.
