Overview

Not all steel pontoons are built equally. If not properly prepared, steel pontoons can rust very quickly — the epoxy coatings that are designed to keep steel safe from corrosion can fail, leaving your steel pontoons unprotected.

Watching your investment sink into the lake — and the bills stack up as you hire cranes and barges to lift your now-submerged steel dock — can be discouraging. Hiring a carrier to take it to a salvage yard for recycling or to a shop for repairs will cost you both in down-time and the cost of freight.

We have a better solution.

NyDock’s 22” sleeve pontoons are compatible with most 24” steel pontoons and will extend the life of your existing dock infrastructure. While other options like foam slurries and inflatable bags are available, none are as durable or reliable as our 22” NyDock sleeve pontoon system. If you’re looking for a long-term solution to keep your docks from sinking, purchase a sleeve today. Once the first sleeve is installed, you will agree that NyDock’s 22” sleeve pontoons are the best product to get your docks floating again and restore your confidence in your docking system.

Our 22” sleeves are made with NyDock’s heavy-duty HDPE carbon black pontoons, complete with fusion-welded end caps to ensure a monolithic seal that is backed by our lifetime warranty. A minimum 5/8” wall thickness and 1”-thick caps ensure that the sleeve is strong enough to be forced into the steel tube even when installed while in the water.

There are many options for installation — removing the dock from the water, then opening the steel tube and installing the new sleeve on land is the most common. This is typically the easiest solution if you have the space and equipment available. Another option is to cut holes in the top of the steel pontoon, use a barge with a crane to lift one end, and then cut the cap and force the sleeve into the pontoon while it rests in the water. However you decide to get the sleeve inside your steel pontoon, once you see the results you will want to breathe new life into all of your sinking steel-pontoon docks.
