Helical piers, also known as helical piles or screw piles, are steel shafts with helical plates that are screwed into the ground to provide foundation support for various structures.
They are commonly used in situations where soil conditions are not strong enough to support traditional foundations. Helical pier installers are professionals trained in the proper installation of these piers, ensuring stability for structures like homes, decks, commercial buildings, and more.
Helical piers consist of a steel shaft with helical plates (or flights) that act like giant screws. They are driven deep into the soil using hydraulic machinery until they reach stable, load-bearing soil or rock layers. The load of the structure is then transferred from the shaft of the pier to the stable soil, providing a solid foundation.
When Are Helical Piers Used?
- Foundation Repairs: In areas where the soil is prone to shifting or erosion, helical piers can stabilize and support an existing foundation.
- New Construction: In regions with poor soil conditions, helical piers offer a reliable foundation for new buildings.
- Decks and Patios: They are also used to support outdoor structures like decks, patios, and porches.
- Retaining Walls: Helical piers provide stability and help prevent soil movement in retaining wall projects.
Why Hire a Professional Helical Pier Installer?
Expertise and Experience
Certified installers have specialized training in soil conditions, pier placement, and load requirements. Their expertise ensures the piers are installed properly, preventing future settlement issues.
Access to Proper Equipment
Helical pier installation requires specific hydraulic equipment that can handle the torque needed to screw the piers into the ground. Professionals have access to and are trained to operate these machines.
Precision and Stability
Proper installation is essential to ensure that the piers reach the appropriate depth and can adequately support the structure. Installers use precise measurements to determine the exact locations and depths for each pier, maximizing stability.
The Installation Process
Site Assessment
The installer begins by assessing the site, testing soil conditions, and identifying potential issues. Soil samples may be taken to determine the depth and type of piers required.
Planning and Design
A customized plan is created for the number and placement of helical piers based on the weight of the structure and soil conditions. This design ensures that the piers will effectively support the foundation.
Pier Installation
Using hydraulic machinery, the installer screws the piers into the ground until they reach a stable layer of soil or bedrock. The depth may vary depending on the soil’s load-bearing capacity.
Load Testing and Connection
After installation, each pier is tested to ensure it can support the intended load. Once testing is complete, the piers are connected to the structure’s foundation using brackets or caps.
Benefits of Helical Piers
- Versatility: They can be installed in almost any type of soil and are suitable for both new construction and repair projects.
- Quick Installation: Helical piers can often be installed faster than traditional concrete foundations because they don’t require curing time.
- Minimal Disturbance: Since helical piers are installed using screw-like rotations, they create minimal disruption to surrounding soil.
- Environmentally Friendly: With less soil displacement and no need for extensive excavation, helical piers are a more sustainable foundation solution.
Choosing the Right Helical Pier Installer
Experience and Certification
Look for installers with a strong track record and relevant certifications. They should be familiar with local soil conditions and have experience in similar projects.
Positive Reviews and References
Check online reviews, testimonials, and references to gauge customer satisfaction. A reputable installer should have a history of successful installations and satisfied clients.
Detailed Proposals
A professional installer will provide a detailed proposal outlining the scope of the project, costs, timeline, and materials. Make sure you understand all terms before proceeding.
Conclusion
Helical pier installers play a crucial role in ensuring the stability and longevity of structures built on challenging soil conditions. By hiring a qualified professional, you can ensure that your foundation is strong and secure, giving you peace of mind for years to come.
