A practical, low-impact alternative to poured concrete footings — fast to install, easy to remove, well-suited to modular and lightweight structures.
A ground screw is a helical steel pile — a galvanized shaft with one or more spiral flights at the bottom — driven into the ground with a hydraulic motor. The flights engage the surrounding soil, and the shaft becomes a slender pier capable of carrying surprisingly large loads.
Ground screws work for modular homes, manufactured buildings, solar panel installations, and lightweight structures. Their adaptability to varied soil conditions makes them especially well-suited to projects with challenging or unpredictable terrain.
Unlike concrete, ground screws need no curing time, no excavation, and no heavy machinery. A deck can be ready to frame on the same day the foundation goes in. The site stays clean, the surrounding landscape stays intact, and the screws themselves can often be pulled and reused on the next project.
A fraction of the time of poured concrete — minutes instead of days.
No excavation, no spoil pile, no concrete curing — the site stays as it was. Most screws are also reusable.
Adaptable to residential, commercial, and industrial use in varied soils — every screw is sized to the loads.
No concrete, no curing time, no heavy machinery — lower labour costs and faster project delivery.
