Foundation profile
| Principle | A compacted, free-draining gravel bed spreads the load and keeps the floor dry. |
|---|---|
| Suitability | Lighter structures — barrels, pods, small sheds and cabins — on reasonable ground. |
| Soils | Best on stable, well-draining soils; poor on soft clay or organic ground without extra depth. |
| Frost heave | A deep, free-draining bed reduces heave by preventing water from pooling and freezing under the sauna. |
| Drainage | Excellent — water passes straight through the gravel away from the structure. |
| Build difficulty | Beginner |
A gravel pad is the simplest cold-climate base: a compacted, free-draining bed that spreads the load and keeps water from pooling and freezing under the sauna. It suits barrels, pods and lighter cabins.
