Here's some tips & frequently asked questions on how to find the right screw pile company for your job
Screw piles are one of the most indestructible deep foundation options for buildings and other structures. Screw piles are screw-like in terms of shape and have helices around them that make driving them into the ground easy. A screw pile foundation can be created with minimum noise and vibration.
With the help of the helices, these steel sections cut into the soil with the utmost ease. These types of piles are suitable for a wide range of ground conditions. Once the screw pile has reached the required depth, it is filled with concrete for the ultimate support and positioning. There is a section of the screw pile that protrudes above the ground; this serves as a connection to the building and can also increase the pile capacity.
Screw piles can go as deep as you want them to. However, this depends on the structure or building that the piles will support, along with the type of soil. You can contact one of the many screw piling contractors through iseekplant to find the accurate screw depth for your project.
You must dig a hole of up to 4 to 5 feet for an average situation, well below the freezing zone. Note that if you use quality piles, they will not fall prey to corrosion even in this zone. The diameter of the hole can be around 14 inches. Apart from that restriction, screw piles can go as deep as 100 feet.
Once you position the pile, you will need to fix it with concrete. You will need approximately 50-60 pounds of concrete for an 8-inch screw pile.
Screw piles cost way less than other concrete bored piers. They are one of the most cost-effective options for building foundations because of their speedy installation and minimum requirement of manpower. Also, they are soil-friendly and do not require vibration or a hammer to be driven.
When you insert a screw pile, it will displace a comparatively less amount of soil. Thus, you need not spend extra dollars on transportation of the soil. When it comes to the screw pile cost, approximately 12 screw piles may cost around $3,000 or less. It is clearly cheaper than other piling options. That is, one screw pile may cost around $200-$300. However, the price may vary according to your area as well as other factors.
Screw piles are usually made of heavy-duty steel. Also, these piles consist of helices that are fixed around the shaft – this also further enhances the life of screw piles.
The average life of a screw pile foundation is 60 to 75 years. That said, some screw piles may last up to a total of 100 years. It may happen if the materials used in piles construction are of high-quality. Also, if the screws are galvanized, they can resist corrosion for a prolonged period.
Still, the life of these piles depends on the type of soil. If the soil is of poor quality, i.e., high water capacity, the piles may ruin faster than average.
