GoliathTech is a helical screw pile network that lists applications including decks, home additions, underpinning and commercial uses.
Ask which pile size and helix configuration are proposed, what torque and depth are targeted, whether engineering is included, who handles permits, and what the warranty covers. Whatever the company, ask for a written scope that names the pile type, quantity, planned depth and torque target, so quotes can be compared line by line. It also helps to ask for recent references on projects of similar size and to confirm current liability insurance and any licenses your state requires.
