Replace floats without pulling your dock out of the water. PermaFloat lift tanks are hollow, one-piece air tanks: fill one with water to sink it under a dock section, then push the water out with air pressure to lift the section. With the dock raised, swap in new floats and lower it back down.
Built for Repeated Use
Extra-strong virgin polyethylene shell with UV inhibitors and a heavy .375" nominal wall
1" NPT threaded insert for a commercial air fitting
3" bottom outlets for water intake and exhaust, shipped sealed so you open only what you need
Designed for residential and light commercial dock repairs. Custom sizes are available; contact us.
Finish the Repair
Pick replacement PermaFloat dock floats in 48 sizes, and swap out worn corners and bolts from our dock hardware while the section is up. If wakes are wearing your dock down, add wave attenuators at the same time.
