What is a ground screw?
A ground screw is a tubular steel shaft with a continuous welded helix thread that is driven directly into the ground using torque — no excavation, no concrete. It creates strong, durable, and removable foundations for virtually any construction application.
No excavation
Driven with low-speed, high-torque equipment. The soil is displaced and compacted, greatly boosting load capacity.
Immediately loadable
Ready to build on minutes after installation — no curing time like concrete requires.
Removable and reusable
Simply reverse the rotation to remove. Ground screws can be relocated or reused on a different project.
Soil or rock
Works in sand, clay, rocky soils, and hard-to-build sites where other foundations cannot reach.
The ground screw advantage over concrete.
Concrete requires excavation, formwork, rebar, pouring, curing, and cleanup. A ground screw eliminates 8 of the 11 steps in the conventional foundation process.
Weather independent
No dry days needed for curing. Installs in any weather condition year-round.
Minimal environmental footprint
No concrete means no cement carbon. ASTM-certified Environmental Product Declaration (Cradle-to-Gate).

The first ICC-certified ground screw foundation in the U.S. Complies with IBC 2015/2018/2021 and IRC.
