Snap Jackets

The SnapJacket system has become very popular with customers in our area because it provides a durable solution to repairing damaged pilings.  This system includes three components. First, a special PVC “jacket” is wrapped around your existing wooden piling. The PVC diameter is slightly larger than that of the piling, and the jacket is not applied flush against the pile. Rather a small space is left between the jacket and the piling that will eventually be filled in order to reinforce and strengthen the piling. The PVC extends about a foot into the ground and above the water to provide additional protection.

Once it’s in position, the jacket is then “snapped” into place with a locking device that helps the PVC to maintain its shape and location around the pile. This also prepares the piling for the following step.

Next, concrete is poured into the jacket, filling any gaps. This serves to provide additional support to the pile, fill any holes left by wear and tear, and extend the longevity of your dock. Gaps left by marine boring organisms, hourglass erosion from the water, and other defects are completely covered and filled. Even holes within the pile that may not be visible to the human eye are filled. Marine organisms eating away at your pilings will die and no longer be able to damage your dock.

Once the concrete dries and hardens, your deck will be safer and more secure than before. Plus, it will last longer.



Replacing piles is a time-consuming endeavor. While there’s a chance that you’ll need to do it at some point, if you can invest in SnapJacket, you can address your piling issues without ripping out your entire dock.


PVC doesn’t experience the same wear and tear as lumber. And when combined with a concrete core, it really stands the test of time. SnapJacket is a durable alternative to replacing wooden piles. Plus, SnapJacket offers a 25-year warranty, though your pilings will likely last much longer.


By protecting your existing piles, SnapJacket helps you get more from your current structure. SnapJacket is an affordable alternative to piling replacement and it also serves to reinforce your existing structure. Plus, by allowing you to get more life out of your dock, SnapJacket helps you save money down the line.
