# The Basics of Foundation Screw Jacks
Foundation screw jacks, also known as helical piles or screw piles, are innovative tools used in construction and engineering to provide support and stability to foundations. These jacks consist of a steel shaft with helical plates that are twisted into the ground to create a strong anchor for buildings, bridges, and other structures.
## How Do Foundation Screw Jacks Work?
Foundation screw jacks work on the principle of helical resistance, where the helical plates act as blades that cut through the soil, creating a secure foundation. This method is more cost-effective and environmentally friendly than traditional concrete foundations, making screw jacks a popular choice for many construction projects.
### Benefits of Using Foundation Screw Jacks
- **Cost-Effective**: Screw jacks are quicker to install and require less labor and materials than traditional foundations, saving time and money.
- **Environmentally Friendly**: Screw jacks have a minimal impact on the environment, as they do not require extensive excavation or concrete pouring.
- **Versatile**: Foundation screw jacks can be used in a variety of soil types and conditions, making them suitable for a wide range of projects.
