PRODUCT DETAILS

Screw piles, also known as helical piers, are a type of deep foundation system used to support structures in challenging soil conditions. They consist of a steel shaft with helical plates (or blades) that are screwed into the ground. These piles are ideal for use in areas with poor soil quality, as they provide a stable foundation without the need for excavation or concrete. Screw piles are often used in construction projects for buildings, bridges, and telecommunications towers. Their quick installation and minimal disruption make them an efficient and cost-effective solution for foundation support.

screw piles are a popular and effective foundation solution that offer several benefits over traditional foundation methods. Firstly, they can be installed quickly and with minimal disturbance to the surrounding area, making them ideal for use in areas with limited space or where there are existing structures. screw piles also provide superior support and stability, as they are designed to distribute the weight of the structure evenly across the soil. This means that they can be used to support a wide range of structures, including residential, commercial, and industrial buildings. Additionally, screw piles are resistant to the effects of moisture and environmental factors, making them a durable and reliable solution that can last for decades with little maintenance. Overall, the use of screw piles can provide significant benefits in terms of cost, efficiency, and performance, making them a popular choice for many construction projects. screw piles have many benefits that make them competitive against other deep foundation technologies! Here are some of the few reasons screw piles stand out.

Size: screw piles use a much smaller working footprint then Caisson or Auger piles. They can be installed in tighter areas using smaller drill rigs and take up less storage on job sites.

Speed: screw piles can be installed much faster than other deep foundation technologies. Between Larger equipment, curing time, weather delays, etc. The Helical Pier goes into the ground with no delay. At a rate of 15 rpm’s and an advancement of 3” per revolution, a typical 30’ section can be completed in about 10 minutes!

Cost: screw piles take much less time to install than other deep foundation Technologies. They can also be loaded immediately after install, compared to other technologies that may need to be curated and tested before moving on to the next step in your plan.

Vibration and Noise: screw piles produce little to no vibration during installation. This minimizes the chance of possible damage to existing structures from the movement of soil. Vibration and noise can disturb surrounding areas/buildings and the people in them. screw piles can prevent disturbance and even damage to surrounding areas.

Our piers can custom manufacture helical piles up to 24” in diameter with a .875 wall and up to a 42” helix to suit your specified material requirements and standards.

All the sizes can be customized.

Applications

Power Transmission Infrastructure‌

Widely used as foundations for high-voltage transmission towers due to their exceptional load-bearing capacity and resistance to lateral forces. The helical design enhances soil friction, ensuring stability in diverse geological conditions

Renewable Energy Projects‌

Essential for solar panel installations (ground-mounted and rooftop systems), providing rapid deployment and corrosion resistance. Hot-dip galvanized variants withstand harsh outdoor environments

Construction Engineering

Temporary support: Used in excavation shoring and trench stabilization.

Permanent foundations: Employed in lightweight structures like greenhouses, signage, and fencing

Specialized Applications‌

Composite soil reinforcement: Combined with CFG (Cement Fly-ash Gravel) piles to improve soft soil strength

Disaster-resistant designs: Patented models incorporate anti-settlement features with T-shaped anchors for flood-prone areas

Advantages Summary‌:

Minimal vibration during installation (ideal for urban areas).

Reusable and adjustable for temporary projects.

Cost-effective compared to traditional concrete foundations
