Postech Screw Piles

What is a Thermal Pile®?

 
Invented in 2007, the screw pile is an innovative technology that allows a thermal or helical pier to be insulated from the inside of a galvanized steel tube – similar to how you would insulate the walls of a house. This insulation system specially created by Postech is durable and permanent, allowing the inside of it to maintain a temperature that prevents the formation of ice or frost at its base.
