Ground Screw Foundation

When it comes to building on uneven ground, sloping terrain, or hard-to-access locations, traditional concrete foundations can be slow, messy, and limiting. Enter the ground screw — an innovative, sustainable, and cost-effective alternative that’s changing how we think about foundations, especially for ground-mounted renewable energy projects.

What is a Ground Screw?

A ground screw foundation is a helical steel pile made from hot-dip galvanized steel, designed for superior corrosion resistance and long-term performance. The screw pile typically consists of:

A drill bit

A drill pipe

Two spiral blades ground screw

A flange

This smart design enables rapid installation without the need for excavation or wet trades.

Superior Performance Through Engineering

One key factor influencing the performance of a ground screw is the blade spacing ratio (S/D = spacing/diameter). According to experimental studies, the optimal blade spacing ratio is between 3 and 4, resulting in the best balance of uplift and compressive load capacity.

Long-Lasting Durability

Depending on the soil conditions, a ground screw can last up to 200 years without significant wear. We proudly offer a 25-year anti-corrosion warranty, ensuring your investment is protected.

Why Choose Ground Screws?

Ground screw foundations are a perfect match for modern construction, particularly in renewable energy applications. Here's why:

Suitable for All Terrain
Ideal for sloping ground, rocky soils, and remote locations.

Time and Cost Efficient
Installation is 70% faster than concrete foundations — and you can build on them immediately.

Clean and Eco-Friendly
No digging. No waste. No concrete. Minimal environmental impact.

Complete Foundation Solution
A fast, accurate, and proven method for stable foundations.

Tested and Certified
Statistically tested for load-bearing, pull-out strength, and wind resistance under stringent standards.

Sustainable and Reusable
No damage to the landscape and fully removable for future use.

Conclusion

Whether you're building a solar farm, a modular structure, or any ground-mounted system, ground screws offer a smarter, greener, and more flexible foundation solution. With proven performance and long-term durability, they are setting a new standard in sustainable ground engineering.
