Precast, prestressed concrete pilings are often the preferred choice for permanent, durable, and economical foundations - especially in marine or bridge environments - due to their excellent adaptability and resistance to corrosion.
Typical sizes: 10 to 12in. for dock projects; larger for bridges.
Typical shapes: 12-in.-square (the most common), plus octagonal and round (cylindrical) in sizes as needed.
Finishes: They are cast in a horizontal position, with an as-cast finish and rotated to their final position at the jobsite by the erection crew.
