Why screw piles for decks

A better footing than concrete.
Concrete footings can shift as reactive clay expands and contracts, causing deck movement and cracks. Our twin-blade screw piles anchor below the active soil layer for greater stability and can be more cost-effective when excavation, labour and curing are considered.

Why use screw piles for a deck instead of concrete stumps?
Screw piles anchor below the reactive soil zone, so they don't lift or sink as clay swells and shrinks through wet and dry seasons the movement that cracks decks and the homes attached to them. You also get quick installation, almost no disturbance to your yard, and no concrete cure time.
How many piles will my deck need?
It depends on deck size, height, bearer and joist spans, and site soil. We size every job from your plans most residential decks use 6 to 20 piles.
How deep do the piles go?
Deep enough to found below the active clay layer and reach the engineered torque typically 1.5 to 3m on residential sites.
