Traditionally in the construction of porches, decks, retaining walls and docks etc, tropical hardwoods or pressure treated woods have been used. As an alternative, the use of Screw Piles provides a durable green alternative thus potentially reducing the use of clear cutting forests. You don’t need, for example, have to remove the terrace first, simply drilling a few holes is already sufficient and the screw piles can be screwed in. A porch without too much clutter or extra work.
