The Earth Truss
More strength. Less steel volume.
The patented Earth Truss™ System revolutionizes foundation technology through innovative design and proven geometry. The reliable truss structure resists wind, gravity, and seismic loads via tension and compression for more efficient use of material.
Ojjo provides a new approach to foundation longevity. With value engineering at its core, the Earth Truss foundation typically requires significantly less steel volume and labor as compared to conventional piles.
Standard Earth Truss features include:
No predrill required.
The hollow Screw Anchor is the heart of Ojjo’s foundation technology. With a crimp collar welded to the top for fast-connect coupling and a hollow tip at the end, the Screw Anchor counter-rotates into the ground while allowing simultaneous deployment of drills. This key innovation reduces costly refusals while saving on predrill costs and labor.
Eliminate subsurface risk.
Subsurface risk presents one of the most unpredictable factors in project economics and can cause unforeseen refusal mitigation costs. Unlike conventional piles, the Earth Truss foundation minimizes embedment depth and can tackle variable soils without the need for additional equipment and materials.
Seamless compatibility with top tracker manufacturers.
Ojjo’s Earth Truss foundation is tracker agnostic and fully compatible with the leading manufacturers, including Nextracker, Array Technologies, and GameChange. Designed to function as part of the tracker system using mating hardware specific to each supplier, Ojjo’s system does not require modifications to any tracker system.
Less grading required.
Customary pile foundations typically only have 1.5 feet of reveal tolerance and can require considerable grading. The Ojjo Earth Truss offers more than 4 feet of reveal tolerance—no matter the truss height—allowing for topography to be absorbed beneath each tracker row, thereby significantly minimizing grading requirements.
Advanced automation streamlines installation.
