Contractors in Virginia can purchase helical piers directly from specialized foundation material suppliers like Walder Foundation Products. These suppliers provide the structural components, installation tools, and technical support required for deep foundation systems. This guide covers how to source the right equipment, understand the installation process, and select the appropriate pier type for your specific soil conditions.
Understanding Helical Piers
Helical piers are steel foundation support systems that are screwed into the ground to reach stable soil or bedrock. They are ideal for areas with expansive clay soils, which are common in parts of Virginia. Unlike driven piles, helical piers can be installed with less vibration and are easier to remove if necessary. This makes them a versatile choice for both new construction and retrofit projects.
Types of Helical Piers
There are several configurations available to contractors. Standard helical piers are used for general load-bearing applications. Pile caps and brackets allow the pier to connect to the existing foundation. Lead sections determine the initial penetration depth, while extensions allow the pier to reach deeper strata. Understanding these components is crucial for accurate material ordering.

Sourcing Materials in Virginia
Contractors in Virginia have several options for purchasing foundation repair materials. Local building supply yards may carry basic items, but specialized suppliers offer a wider range of deep foundation systems. Walder Foundation Products is a national supplier that ships helical piles and related components to contractors across the United States, including Virginia.
Benefits of Specialized Suppliers
Specialized suppliers like Walder Foundation Products provide more than just hardware. They offer technical documentation, installation guides, and customer support. This expertise helps contractors ensure their installations meet local building codes and manufacturer specifications. Access to a wide inventory also reduces project delays.
Shipping and Logistics
When ordering heavy steel components, shipping logistics are a key consideration. Suppliers that ship nationwide can often deliver to job sites in Virginia within a few business days. Contractors should verify shipping costs and lead times before placing an order. Planning ahead ensures that materials arrive when the crew is ready to install.
Foundation Repair Contractors
Foundation repair contractors in Virginia use a variety of methods to stabilize structures. While some specialize in push piers, others focus on helical systems. The choice of method depends on the specific problem, such as settling, heaving, or lateral movement. Contractors must be trained and certified to install these systems correctly.
Choosing the Right System
Selecting the right foundation system requires a site assessment. Soil borings and load calculations determine the required pier capacity. Helical piers are often chosen for their precision and minimal disruption. Push piers, on the other hand, are driven into the ground and may be better suited for certain soil conditions. A thorough evaluation ensures the best long-term solution.
Contractor Resources
Suppliers often provide resources to help contractors succeed. This includes marketing materials, technical training, and pricing programs. Requesting contractor pricing can help businesses secure better rates on bulk orders. These resources support contractors in growing their foundation repair services.
Installation Equipment and Tools
Installing helical piers requires specific equipment. A hydraulic or electric drive head is used to screw the pier into the ground. This equipment can be rented or purchased. Contractors also need torque wrenches to measure the installation resistance, which indicates the load capacity of the pier. Proper tools ensure a safe and effective installation.
Essential Tools
Beyond the drive head, contractors need a range of hand and power tools. These include angle grinders for cutting extensions, welding equipment for attaching brackets, and leveling tools. Safety gear is also essential, including hard hats, gloves, and eye protection. Having the right tools on hand improves efficiency and reduces the risk of accidents.
Training and Certification
Comparison of Foundation Systems
Understanding the differences between foundation systems helps contractors make informed decisions. The table below compares helical piers and push piers, two common deep foundation solutions.
| Feature | Helical Piers | Push Piers |
|---|---|---|
| Installation Method | Screwed into ground | Driven into ground |
| Vibration | Low | High |
| Removability | Easy to remove | Difficult to remove |
| Best For | Expansive soils, retrofits | Stiff soils, new construction |
| Equipment Needed | Drive head, torque wrench | Hydraulic ram, heavy equipment |
Both systems have their place in foundation repair. The choice depends on the specific site conditions and project requirements. Contractors should evaluate each option carefully before proceeding.

Frequently Asked Questions
What are helical piers used for?
Helical piers are used to stabilize foundations that are settling or moving due to soil conditions. They provide a deep anchor point that bypasses unstable soil layers.
Can I install helical piers myself?
While it is technically possible, it is not recommended. Installation requires specialized equipment and expertise to ensure the pier is installed to the correct depth and torque. Professional contractors are trained to handle this safely.
How much do helical piers cost?
Costs vary based on the number of piers, depth, and load requirements. Contractors can request pricing from suppliers like Walder Foundation Products to get accurate quotes for their projects.
Are helical piers permanent?
Yes, helical piers are designed to be a permanent solution. They are made of galvanized steel and are installed to provide long-term stability to the foundation.
What tools are needed to install helical piers?
Do helical piers work in all soil types?
Helical piers work in most soil types, including expansive clays and sandy soils. However, the specific configuration may vary depending on the soil conditions and load requirements.
