The SnapJacket is the toughest and longest lasting option to preserve or repair aging marine piling. The SnapJacket’s design makes it very easy to install, keeping dock repair costs to a minimum. By opening up and easily locking back together, using the SnapJacket does not require you to disassemble any portion of the structure built on top of the piles. Gone are the days of needing large barges to come in and take apart portions of the dock to replace a single pole. Pole replacement can be very costly, especially if there is a structure built on top of it, such as a boathouse or boatlift. Once the jacket is filled with cement, all marine boring organisms that are eating away the inside are instantly killed. The concrete flows into the voids creating a new solid piling. Using the SnapJacket will help you preserve your piling that are beginning to show signs of aging, and with proper engineering the SnapJacket can even restore a completely broken piling to beyond its original strength. The concept of jacketing pylons is nothing new, we have just made it affordable to a homeowner for the first time. Check out the video’s below for more information on how they work!
SnapJacket – Piling Repair Jacket for Timber Pilings
Snapjacket is constructed using UV protected PVC material. It’s extremely durable and we guarantee it will last at least 25 years. In reality, it likely will last much longer than that. The Timber Council published a study that says marine pilings using this technology will last “indefinitely”. You can view that study here.
Once you watch our installation video and have all the materials on hand, it should take an experience crew of 2 people about 5 minutes per piling to place the jacket. Concrete can be placed in as little as 2 minutes per pole, depending on the filling method. A homeowner would likely take about 20 mintues to mix bags of cement and pour them into the void.
We recommend that you have at least 1.5 inches of annular space around the jacket. When pumping cement into the jacket, using a flexible flat hose over the end of the cement hose will allow you to fit the hose into tighter voids, so it is easier to use a tighter jacket. When pouring mixed cement in from the top, it is easier to have more space to allow the concrete to fall in easier. You will need more concrete but will save yourself the headache of getting the cement to fall through such a small void.
You can, but we recommend upgrading to a larger diameter ring to accommodate the jackets larger diameter. Retrofitting a floating dock with SnapJackets can be tricky as adding the extra thickness around the piling can effect the way a floating dock moves with the tide. Having a very tight space with little wiggle room can scratch up the jacket as the dock repeatedly floats up and down. To best protect the jacket, we recommend upgrading to a hoop with rollers or a plastic liner on the inside. See the Pile Glide by Carolina Water Works or something similar. We recommend taking extra precautions when using the SnapJacket with a floating dock piling. Even with these Specialized hoops, wave action and tidal changes can cause the floater to hang up on the SnapJacket, causing damage. The SnapJacket’s warranty does not cover any damage done to the jacket by impact, weather it be by boat or parts of the structure.
You sure can! Just use an abrasive brush to remove marine growth. However, cleaning the SnapJacket is not required and has no effect on its useful life. The plastic is far easier to keep clean than wood. Pro tip: by using flexible irrigation line to make a circle around the jacket, the ring will float up and down around the pole. By going up and down with the tide everyday it will agitate the barnacles off before they have a chance to latch on and die, leaving you a much cleaner and more aesthetically pleasing pile.
