Deck installation enhances both the enjoyment and curb appeal of your property. While concrete foundations are most common during installation, many homeowners are choosing helical pier systems these days. Also known as screw piles, helical piers offer a quick process and lasting reliability for your deck's foundation. Here are a few essential facts about them to help you make an informed decision. 

4 FAQ for Helical Piers & Deck Installation

What are helical piers?

Helical piers or screw piles are long shafts made from galvanized steel. At one end of the shaft is a circular flange, which allows the shaft to be easily rotated into the soil. In essence, these supports are similar to giant screws that possess the weight-bearing capacity to keep a deck safe and stable.  

How does screw pile installation work?

Many installations involve the use of a bore piling machine, which drives the pier into the ground using massive amounts of force. In most cases, no pre-drilling is required. However, the presence of bedrock under the installation site can require pre-drilling to ensure the pier is installed correctly. 

How do piers create a solid foundation?

Creating a solid foundation under your deck is a major safety concern. Fortunately, helical systems offer assurance of foundational stability thanks to the way they're installed. The rotational resistance of the pier is measured as it's pushed into the ground, which ensures it reaches the proper depth for optimum soil bearing capacity. These calculations allow installers to make accurate, reasonable decisions when determining the depth. 

What benefits can I expect?

In addition to good foundation stability, screw piles can be installed quickly. You won't need to wait for concrete to set or cure, as the foundation is ready as soon as the piers are installed. Heaving or settling of piers is also less of a concern than with concrete foundations due to the depth of installation. By registering the PSI (Pounds per Square Inch) while installing the piers, we are able to determine when we have reached solid and adequate soil to support the structure.
