Helical / Screw Piles for Dock and Boathouse Foundations
You’ll always arrive safely!
Unlike wood piles, GoliathTech galvanized steel screw piles are the ideal choice for supporting docks and boathouses. Due to their corrosion resistance and superior engineering, our helical (screw) piles provide strength, safety, and durability. Anchored deep in the ground of waterways, they can solidly support most types of docks and boathouses. With helices ranging in size from 8" to 29" in diameter, our helical (screw) piles offer optimal compression and tension performance.
A rapid and damage-free installation
Our quick installation process, carried out with light and compact equipment, allows you to avoid excavation and begin building as soon as the installation of the helical (screw) piles is complete. In addition, we can install them in all types of soils and spaces, even restricted ones that would normally be hard to reach. With the help of our certified installers, GoliathTech’s screw piles will support the foundation of your dock or boathouse for many years to come.
Before installing your dock or boathouse using screw piles, contact one of our certified installers so that they can determine the type, amount, and location of the helical (screw) piles to be installed. Depending on your project, they will be able to estimate the costs.
