Helical Pier Installation in Raleigh

Helical pier installation is a specialized foundation solution used in Raleigh, North Carolina, and surrounding areas. This technique offers a reliable and efficient method for stabilizing and supporting structures. Helical piers, also known as screw piles, are installed deep into the ground to provide a solid foundation. This process is especially useful in areas with challenging soil conditions. Helical pier installation is a cost-effective solution for new construction and foundation repair.

Understanding Helical Piers

Helical piers are steel shafts with helical plates welded to them. These plates resemble large screws. These plates provide the gripping power needed to secure the pier firmly in the ground. The size and number of helical plates are determined by the soil conditions and the load requirements of the structure. Engineers carefully calculate these factors to ensure a stable and long-lasting foundation. The piers are driven into the earth using specialized equipment until they reach stable, load-bearing soil.

Types of Helical Piers

1. Round Shaft Helical Piers: These are the most common type, used for a wide range of applications.
2. Square Shaft Helical Piers: These offer greater torsional resistance and are often used in heavier load situations.

Advantages of Helical Piers

1. Minimal Soil Disturbance: Installation causes less disruption to the surrounding landscape compared to traditional methods.
2. Quick Installation: The process is generally faster than other foundation methods.
3. All-Weather Installation: Helical piers can be installed in most weather conditions, including rain and snow.
4. Environmentally Friendly: The installation process is considered environmentally friendly due to minimal soil disturbance and no concrete curing required.

The Helical Pier Installation Process in Raleigh

The helical pier installation process begins with a thorough site evaluation. Soil conditions are assessed to determine the appropriate pier size and depth. The installation process is carefully planned and executed by experienced professionals. Specialized equipment is used to drive the helical piers into the ground. The process continues until the piers reach the desired load-bearing strata. This ensures a stable and secure foundation for the structure.

Steps Involved

1. Site Evaluation: A thorough assessment of the soil conditions is conducted.
2. Pilot Hole Drilling: A small pilot hole is sometimes drilled to guide the helical pier.
3. Pier Installation: Helical piers are driven into the ground using hydraulic equipment.
4. Load Testing: Load tests are performed to verify the capacity of the installed piers.
5. Bracing and Connection: The piers are then braced and connected to the structure’s foundation.
