Can screw piles be used for a full house slab, not just decks?

Yes — while screw piles are commonly associated with decks and lighter structures, they’re genuinely also used for main residential foundations, particularly for elevated or suspended floor designs on challenging sites.

Suitability for a full house depends on your specific soil conditions and building loads, assessed by your engineer the same way any foundation system is properly evaluated — not automatically ruled in or out based on typical use cases alone.

Where genuinely appropriate for your site, screw piles offer the same speed and reduced disruption advantages for a house foundation as they do for smaller structures.
