Sustainable Foundations
When executing a construction project, do you focus on ecology, safety, and efficiency? These aspects must be considered when planning construction work. The use of screw foundations in foundation structures provides an innovative and sustainable alternative to traditional concrete foundations.
Applications
- Solar Power Plant Construction
- Residential and Container Structures
- Road Signs
- Railway Infrastructure
- Wood and Landscaping Construction
Ground Screw Foundations
Ground Screw foundations are based on the principle of pile foundations, which are one of the oldest and most reliable types of foundations. The Ground Screw foundation uses an earth screw made of galvanized steel pipes with screw blades welded onto them, which effectively handle both horizontal and vertical loads.
These are installed using a dedicated pile driver, where rotation and pushing are controlled during installation. Ground Screws, designed with the right size and material selection based on load and soil conditions, offer performance equal to or better than traditional concrete foundations in terms of load-bearing strength.
With excellent construction efficiency and cost-effectiveness, combined with compact and mobile specialized pile drivers, Ground Screw foundations can be installed on sloped terrain or in narrow, difficult-to-work sites, shortening the construction time compared to conventional concrete foundations.
Additionally, since Ground Screws are directly rotated into the ground, they do not negatively impact the soil, avoiding soil contamination. The specialized pile driver is compact and lightweight, reducing the risk of damaging the ground. Ground Screws can be easily removed by reversing the rotation, eliminating disposal costs for industrial waste. The extracted Ground Screws, made of steel, can be recycled or reused if undamaged.
Ground Screws have been used in solar power plants, residential areas, road signs, railway infrastructure, and landscaping in over 35 countries.

Benefits of Ground Screws
Sustainability
- Ground Screws are installed by directly rotating the piles into the ground, so they do not harm the soil or cause soil contamination.
- The compact and lightweight pile driver prevents damage to the ground.
- Ground Screws can be easily removed by reversing the screw motion, which avoids industrial waste disposal costs. They can also be recycled or reused if undamaged.
Excellent Efficiency
- The specialized pile driver is compact and lightweight, enabling installation in difficult-to-reach areas.
- Because the piles are rotated into the ground, there is no need for curing time as with concrete foundations, reducing the construction time.
- Ground Screws are based on principles proven over centuries, making the technology highly mature.
- Depending on the soil and screw type, Ground Screws can handle up to 15 tons of compressive load.
- The pile driver offers excellent control over rotation and pressing, ensuring high-quality pile installation.
