Helical Piers and Pile Driving Anchor Services | Helical piles, also called helical pier, offer foundation support for the structures sitting above them. Screw piles are embedded deep into the ground and disperses the weight from the surface. The purpose of a helical pile is to provide foundation support for all different types of structures, no matter the type or size. Helical piles are dug underground in order to distribute the weight that they are supporting. They serve as an anchor to structures and buildings.
Some of the other advantages of helical pile installation includes:
- Can sustain a wide range of loads
- Can be adapted to a variety of angles
- Less cost that driving or drilling holes
- Minimal vibration and noise during the installation process
- Installation is not affected by the weather
- Minimal equipment needed
- Ideal for areas that are hard to access or that have a low-headroom
- Can be removed easily
- No excavation needed
- No concrete needed
- Quick and efficient installation
How Do Helical Piles Work
Helical piles are installed by being twisted into the soil like a corkscrew by an excavator. As the screw pile disappears into the ground, extension segments are connected and screwed into the soil. This results in a single pile that extends hundreds of feet below the surface. For heavier structures, concrete can be incorporated for extra stability. In most cases, however, the helical screw is strong enough on it’s own.
How Deep Can Helical Piles Go
Most helical piles are installed between 10 to 25 feet below the soil, but may be required to extend deeper. Some piles can go as deep as 100 feet underground. Screws can hold more than 500 tons; like to support a 10-story building. Helical piles are the best to use for foundations because they’re so quick to install and only require few workers to get the job done.
Benefits of Helical Pile Installation
There are many advantages to using helical piling, such as their low cost. In many cases, helical piles offer significant advantages over other digging systems. Helical pile installation is a type of foundation system that does not need to wait until concrete or the grout hardens. One of the main benefits would be that it produces minimal vibration and noise during the installation process. This is ideal for residential areas as it will not disturb the peace. Screws can be installed and removed easily with no excavation required. The piles are also very strong, holding a wide range of loads and adapting to many angles.
