PrincipleThe structure sits on heavy timber or steel runners that rest on a prepared bed.
SuitabilityBarrels and lighter cabins that may need to be moved or placed without excavation.
SoilsBest on a level, compacted gravel bed; poor directly on soft or uneven ground.
Frost heaveModerate — skids ride on the surface, so the whole unit moves with seasonal heave together.
DrainageGood when set on a free-draining gravel bed that keeps the runners dry.
Build difficultyBeginner

A skid foundation lets a barrel or light cabin sit on heavy runners over a gravel bed, with no excavation and the option to relocate. It rides on the surface, so a level, free-draining bed is essential.
