Ground Screws & Helical Piles Foundations

Screw Foundation Solutions for Any Soil, Load, or Structure

Why Foundations Fail and How to Avoid It

Choosing the right foundation system is one of the most critical decisions on any construction site — yet it’s also one of the most overlooked. Too often, contractors and engineers default to traditional concrete piers or footings without considering the risks: slow installation, weather delays, uneven settlement, and costly non‑compliance with building codes. These missteps can add weeks to schedules and thousands to budgets.

Ground conditions rarely cooperate with standard approaches. Sandy soils, high water tables, frost‑heave zones, or restricted access can make concrete and standard foundation screws impractical. In many cases, entire installations fail inspection because they simply don’t meet required load capacities or code specifications.

Today’s projects demand smarter solutions that keep pace with tight timelines, comply with U.S. standards like ASTM and IPC, and adapt to unpredictable ground conditions. Failing to plan for these challenges doesn’t just risk your project — it risks your reputation.

Heavy‑duty screw foundations provide superior load‑bearing performance in challenging soils and meet ASTM and IPC standards for permanent installations.

Adjustable Foundation Screws

Removable and Reusable Screw Anchors

Ideal for uneven or sloped terrain, adjustable foundation screws feature integrated leveling heads for precise height correction and secure footing. These earth screw foundations ensure stable, level installations even on difficult terrain, while maintaining fast installation and compliance with structural requirements.Designed for sustainability and flexibility, removable screw anchors can be extracted and reused in future projects. Perfect for temporary foundations, event structures, and projects in sensitive environments, they reduce material waste and allow for easy site restoration after use.

What Makes Ground Screws and Helical Piles the Smarter Choice

Fast Installation
Ground screws and helical piles install quickly without curing time, heavy excavation, or weather‑related delays. This allows you to keep projects on schedule and minimize site disruption while maintaining strong, code‑compliant foundations.

Adaptable to Any Soil
Engineered to perform in a wide range of soil conditions — including clay, sand, and frost‑prone areas — our screw foundations deliver reliable load‑bearing capacity where traditional concrete often fails.

Code‑Compliant Performance
All ground screws and helical piles meet U.S. standards such as ASTM and IPC. You can build with confidence knowing your foundation system passes inspection and supports long‑term structural integrity.

Environmentally Responsible
With no concrete, minimal excavation, and the option to reuse removable screw anchors, these systems reduce material waste and protect sensitive environments. Ideal for sustainable construction practices.

Permanent or Temporary Solutions
Our foundation screws are suited for both permanent and temporary applications, from modular homes to event structures, giving you flexibility to adapt as project needs change.

Cost‑Effective and Predictable
By eliminating delays, reducing labor costs, and minimizing rework due to soil challenges, earth screw foundations help you control budgets and avoid costly surprises.

Ideal for Modular and Manufactured Construction
Ground screws and helical piles are perfectly suited for modular buildings and manufactured homes. They deliver fast, level, and code‑compliant foundations that align with factory‑built construction schedules, ensuring efficient installation on site.

Compliance & Standards

Every project must meet strict regulatory and structural standards — and your foundation system is no exception. Our ground screws and helical piles are engineered to comply with U.S. codes, including ASTM and IPC, ensuring every installation passes inspection and performs reliably for years to come.

Each foundation screw and pile is manufactured and tested to meet or exceed industry benchmarks for load‑bearing capacity, corrosion resistance, and long‑term durability. This makes them suitable for both residential and commercial applications, even in jurisdictions with demanding requirements.

Working with solutions that are already code‑compliant saves time, reduces administrative headaches, and protects your project from costly delays or rework. When you build with our screw foundation systems, you can be confident they align with the expectations of engineers, inspectors, and stakeholders alike.

FAQ

What soil conditions are suitable for ground screws and helical piles?

Ground screws and helical piles are designed to perform in a wide variety of soil conditions, including clay, sand, gravel, and frost‑prone soils. Their load‑bearing capacity is determined by soil type and density, so a proper geotechnical assessment is recommended before specifying these screw foundation systems. Unlike concrete, they can adapt to inconsistent or poor soils and still provide stable, code‑compliant support.

How do screw foundations comply with U.S. building codes?

Both ground screws and helical piles are engineered to meet U.S. standards such as ASTM and IPC. Their performance can be calculated and verified according to load requirements and site conditions, making them an accepted alternative to traditional foundations in most jurisdictions. It is important to select the right size and type of screw foundation for your project to ensure full compliance.

What are the typical load capacities of ground screws and helical piles?

Load capacities vary depending on the diameter, length, and soil conditions. Standard ground screws are suitable for light to medium‑weight structures like decks, sheds, and small modular buildings. Heavy‑duty helical piles are capable of supporting significantly higher loads for permanent commercial and residential structures. Project‑specific engineering is advised to determine exact capacities.

Can screw foundations be used for permanent structures?

Yes. Both ground screws and helical piles are designed for permanent as well as temporary applications. When specified and installed correctly, they provide long‑term, code‑compliant performance and durability equal to or exceeding traditional concrete footings. They are often preferred for modular construction, solar fields, and environmentally sensitive sites due to their minimal impact and reliability.

How do screw foundations perform compared to traditional concrete in challenging environments?

Screw foundations excel in conditions where traditional concrete footings struggle. They can be installed in wet, cold, or uneven environments without waiting for curing or perfect weather conditions. Ground screws and helical piles minimize site disturbance and adapt to variable soil profiles, ensuring reliable, code‑compliant support even where concrete would require extensive preparation or fail to meet load requirements.

Why are screw foundations ideal for modular and manufactured homes?

Ground screws and helical piles align perfectly with the off‑site construction model of modular and manufactured homes. They can be installed quickly, precisely leveled, and load‑tested before delivery of the building, allowing seamless integration with factory‑built components while meeting code requirements.
