What are Ballast Tubes?

FLSI Sand Bags are typically custom fabricated ballast tubes made from flexible plastic that’s reinforced to help contain the ballast material and keep the shape it was made into. Our ballast tubes are made to order and are all completely custom in virtually any diameter and length. We can also add additional material for grommets to fasten the tubes together in a string to create a large, modular section as opposed to a large, heavy and hard to maneuver ballast tube. Also available are NSF-61 certified materials; such as the liner, sand and hardware, for drinking water applications, along with materials that can resist harsh chemicals and acids. Contact us today to see how FLSI can facilitate your ballast tube needs!

How can FLSI help you?

FLSI custom fabricates all of our liners in our state-of-the-art fabrication facility. These liners are used to protect the environment from corrosion, to prevent leaks and contaminants from leaching into the ground. We fabricate both flexible plastic drop-in liners and rigid plastic drop-in liners. We also fabricate rigid plastic free-standing tanks. We are professional, trained and certified installers that can perform any size project.
