Ground Screws

PrincipleSteel screw piles driven below the frost line carry the structure on point supports.
SuitabilityMost framed cabins, cubes, pods and sheds, especially where the floor should sit clear of snow.
SoilsWork in a wide range of soils; length and number are matched to ground conditions.
Frost heaveExcellent — piles reach below the frost line, so seasonal heave has little grip on them.
DrainageVery good — the structure is lifted, leaving air and drainage beneath the floor.
Build difficultyIntermediate

Ground screws are the archive’s go-to cold-climate foundation: steel piles driven below the frost line that lift the floor clear of snow with minimal disturbance. They suit most framed cabins, cubes, pods and sheds.
