Prefab timber house on a slope supported by screw pile foundations
Application 03

Polyhouses, prefab & modular homes

Prefab, modular homes & polyhouses are light, but they still need a level base to sit on. We install piles to match the home's frame, which can be directly bolted. This works even on sloping or remote land, with no digging and dependency on local civil contractors. Screw pile can help you build in the remotest of the location with minimal labor.

Pile types used

Modular house single-helix pile · Light-gauge ground screw · Ground screw with single helix
