Pros And Cons of Screw Piles

Screw piles are extremely important in the construction of any building or structure on any type of soil, since they keep your foundation stable.



What are screw piles?

Screw piles, also called helical or screw piers, are steel piling systems anchored into the ground with screws. They are used in many types of construction and are very popular in earthquake-prone and flood-prone areas because they require minimum soil displacement and can withstand tensile and compression loads. Whether you need to construct a bridge or a cabin, screw piles are an excellent choice for this type of foundation. The good news is that they are very durable and can withstand a wide range of ground conditions.

Screw piles benefits

The screw pile is an efficient and fast way to install a foundation. The installation process is quick and minimally disruptive to the surrounding soil. Screw piles are constructed with hollow steel bars that are helix-shaped. They are usually filled with concrete, which increases their capacity. The type of shaft and helix-like construction of screw piles can be adjusted to meet any specific requirement. In general, screw piles are installed at a depth that is determined by the ground conditions, which is usually more than one meter.

One of the major benefits of screw pile foundations is the ease of access to the construction site. The slender diameter of the shaft is particularly beneficial, as it reduces the chances of bumping into obstacles when screwing into the ground. 

Another key benefit of screw piles is that they are completely recyclable. This makes them better for the environment than concrete. The screws can be reused as good as new, with minimal impact on the local environment. Unlike concrete, there is no need for excavation, and the installation of these structures requires no special skills or training.

Screw piles disadvantage

Although screw piles are a useful option for foundations, there is one major disadvantage to this type of foundations. As they are fabricated in sections, they are difficult to adjust. Comparing tof helical anchors, which can be extended and cut according to the project's needs, this is not the case with screw piles. 

The second disadvantage is that you can’t install them by yourself and have to hire a third-party company to accomplish the construction works.

Screw piles price

Screw piles are more economical than concrete piles and can be installed below frost levels. They are also more durable than other types of foundations and have a 50-year design life. Their cost-effectiveness is result of the fact that they can be installed by a single machine. In addition, they do not produce waste, which is important if you're working on a tight budget. When installed properly, they can save you time and money.
