Ice lifting (or “ice-jacking”) causes significant damage to Wisconsin piers when freezing water expands and adheres to pilings, pulling them from the lakebed as water levels fluctuate. This often destroys docks and boat lifts, particularly on larger lakes necessitating removal, de-icers, or specialized, heavy-duty structures to prevent damage.

Ice jacking occurs when the water rises to a higher level, freezes, and then recedes, leaving a layer of ice along the high-water mark. As the water settles, it freezes again, leaving another layer of ice. As the water rises again, it breaks the second level of ice and pushes it into the first.
The process is similar to jacking up a car to change a tire, hence the name, “ice jacking.” If ice jacking is allowed to persist, pressure will increase, and it can eventually lift your dock enough to pull the pilings out of their foundation, and sometimes even snap them in half.

The Ice Jacking Progression
- Freezing and Gripping: As water temperatures drop, ice forms around a pier leg or piling, locking it firmly.
- Water Level Change: The water level rises due to wind or lake ice expansion forcing water up through cracks. The ice sheet rises with it, pulling the pier leg up.
- Refreezing: As the water level recedes or the ice settles, the ice freezes at a new position around the piling.
- Repetition: This cycle repeats throughout the winter, gradually “jacking” the post out of the lake bed.
Common Causes and Effects
- Water Level Fluctuations: Tides are a common cause of lifting on the coast. In the Great Lakes region, wind and rapid weather changes or manual water regulation (dams) can cause similar fluctuations.
- Ice Expansion: When water turns to ice, it expands by approximately 9-10%. This puts massive pressure on the shore, sometimes called an “ice shove” or “ice ridge” formation, which can damage shorelines and attached structures.
- Damage: Pier legs can be lifted out of their foundations, resulting in crooked, unstable, or destroyed docks.

Prevention
The most effective way to prevent ice jacking is to keep an ice-free zone around the pilings, often achieved by:
- Installing De-icers or Bubblers: Using agitators or air blowers to bring warmer, deeper water to the surface, preventing thick ice from forming around the pilings.
- Removal: Removing floating or temporary dock sections for the winter.
- Using Sleeves or wrap: Placing pile sleeves or wrap over the pilings to reduce the grip of the ice.
Dock Protection Solutions

De-icer
A dock de-icer (Ice Eater) is a great solution, which works as an agitator by circulating the water toward the surface. The device is submerged underwater, where it creates a thrust of water toward the surface. This creates a vertical current effect, which keeps the water moving outward to open up large holes in the ice.

A dock de-icer can also be angled closer to horizontal to create a longer but narrower opening.

Dock Bubblers
Bubblers work by releasing small air bubbles through an underwater hose. The hose has small perforations and is powered by an air compressor. Bubblers can be beneficial if the water near your dock is shallow as they don’t stir up as much sediment as agitators can in shallow water.
Removal
The safest method for preventing ice damage is to completely remove three season and floating pier sections from the water and store them on dry land. Store them far enough away from the shore to protect from ice shoves. This eliminates the risk of ice damage altogether.

Protective Sleeves or Wrap
Placing HDPE (high-density polyethylene) sleeves or specialty wraps on pilings prevent ice jacking by reducing friction, allowing ice to slide along the pile rather than lifting it as water levels shift. These jackets, which can be installed before or after installation, often feature smooth surfaces to prevent ice adhesion.
Using these preventive methods help maintain the structural integrity of the pile, preventing the need to replace or re-drive pilings that have been lifted by ice.

Are you a Pro with a Pontoon Boat?
Pontoon boats are a relaxing way to enjoy boating any season of the year.
It’s Fall, and there are still days when you will wish you could be out on a pontoon boat. It might be a little cooler, but after the hot summer, it will be refreshing.
Pontoon Boats are unique
Pontoon boats have their own style with many amenities available. These boats are different in many ways from a normal powerboat. Handling them is another animal to tackle. Check out this article to get the most use of your pontoon boat.
Docking and Undocking
Pontoon boats leave the dock like any other vessel on the water. Yet, their body shape creates more surface area for the wind to push around. It amounts to a “giant sail.”, the tubes and vertical fences found around the deck act as a sail.
Adding to that difficulty are the boat tubes, which provide your floatation. Large gusts of wind are your mortal enemy. They can knock you off course on the water. The ability to push your pontoon into other boats means you need to know how to handle a pontoon boat. Plus, you must have stellar insurance coverage. SEE
To counter the winds, you have to be aware of them at all times. The pontoon boat’s secret is its exceptional control when used with short bursts of power. Regardless of what type of boat you use, idle the engine and point the motor in the direction you want to go. Then shift into gear. Next, use short bursts of power as you steer the boat. Before you know it, you’ll be out of the dock.
You’ll use the same understanding of the wind and maneuvers when heading back into the marina. Docking any powerboat (pontoons included) requires a little more side-to-side motion. You can learn more about these actions via this link.
Beaching
Beaching or mooring your boat to swim is half the fun of boating, no matter what type of vessel you own. People love beaching their boats to explore islands or soak up the sun. Luckily, both are simple processes and the same for every type of powerboat.
Start by traveling slow when you hit shallow waters, so you don’t damage your motor. Beaching requires you to push the front end of your vessel onto land. Do this carefully to prevent damage to the tubes.
Don’t head onto the beach too far; allow enough room to spin the boat around out into the water using the motor.
For mooring, make sure you have the proper tools to secure your boat via the anchor. Pontoon boats are more buoyant, so use fenders to protect your boat from other vessels.
Turning and Handling
Pontoon boats soar across the water, which makes handling them a ton of fun. Before you lose yourself in the moment, remember that there are no lanes out on the water. Always check your surroundings before making a turn or spinning your boat around.
With that safety tip in mind, you’re ready to tackle the water. Pontoon boats are very stable. You don’t have to worry about flipping or rolling the boat over in normal conditions.
But rough waves and tight turns mean you can’t rule out the possibility. Still, it isn’t much of a concern for the modern pontoon boat.
You do have to worry about causing the propeller to leave the water when making a tight turn. You can either back off of the turn, deaccelerate or trim the engine downwards to remedy the issue. When making sharp turns, equipment and people on your deck are likely to be tossed to one side depending on the speed. Do they have life preservers?
Acceleration
Once you hit open waters, you’re ready to pick up speed. Don’t treat your pontoon boat like a race car, though. Instead, speed up steadily until you reach your desired speed. Keep in mind that the bow will level out, which means you’ll need to trim the engine if you want more speed.
Your engine might rise too far out of the water as you speed up. That’s normal and easy to fix by trimming the motor. Your boat may slow down, and you’ll hear a howling sound near the propeller. Or, the boat will lose a little stabilization when this happens.
Keep in mind that every boat comes with a manufacturer’s recommendation for top speeds or RPM. Most recommend 75% of fully open throttle. It helps to read up on this statistic before pushing your boat to its limits. Use less throttle for more fuel efficiency.
Keep in mind that more crowded waters demand slower speeds. There are rarely legal speed limits on open water, so be mindful of other boaters in the area. Keep an eye out for swimmers as you approach other boats or the shoreline.
Stability Tips in Rough Waters
A pontoon boat handles well, even in rough water, thanks to its dual or triple hull design. Yet, even with the added help, you need to drive a pontoon boat carefully in these conditions.
Experienced boaters recommended that you keep an even load on board. To do this, you must include both objects and passengers. When rough waters arise, make sure your passengers know to even out their weight on deck and sit down. Don’t forget to make them wear life preservers for their safety. The larger your boat, the easier this is to maintain.
Try to avoid heading straight into giant waves. Excessive splashing could damage the electronics in your boat if they take on water. If you must head nose-first into oncoming waves, trim the engine down to help keep the boat’s nose/bow upward. Otherwise, take the waves at a 30 to 40-degree angle.
Finally, sports handling packages are an enormous benefit here. These include better nosecones, power-assisted steering, and higher horsepower to combat choppy waters.

Pontoon Boat Lift
That means don’t head out onto the water when you know a storm is on the way. A pontoon boat is an investment you don’t want to risk for a few more minutes of fun. If inclement weather strikes, head back to the dock and put your boat back on your lift.

Does Shoreline Stabilization Work?
Creating shoreline stabilization sounds pretty easy to do. Just throw some big rocks on the shore. Right!? But when you leave your shoreline, do you really think it will do the job you intended it to do?
In reality, it is labor and equipment intensive and requires special equipment and permits.
What do I have to gain by stabilization of my shoreline?
You have a lot to gain from shoreline stabilization. Waterfront property is always more expensive in comparison to a property with no waterfront. Therefore by installing erosion control (in this case, riprap), you are protecting your investment. If the shoreline is washed away or damaged, your property values diminish along with it.

Shoreline Stabilization required
Shoreline erosion can happen from numerous conditions. The typical way is from waves crashing into the shoreline. As this happens, the waves begin to undermine the foundation of the beachfront. When the shoreline is not stable, you’ll lose your lawn, trees, shrubs, and your waterfront. When a bank is unstable, it’s not safe.
There are different ways to “shore” up a beach. The two most common ways to stabilize your shoreline – riprap (limestone or granite) and steel sheet piling.
The riprap method consists of using 8″ – 30″ stones to cover the shoreline’s exposed areas. Adding riprap allows the waves to lose their energy as they pass over and into the rocks.
NOW for the proof!
Pictures are worth a thousand words!
Have you ever watched riprap in action?
Thanks to one of our many customers, we have a short video that demonstrates how riprap works. Press below –
Notice how the waves start to climb the riprap, but they dissipate in the rocks’ openings. Once the water drops below the riprap’s outer surface, it is further dispersed by more rocks under the surface.
In a major storm, some waves go so high that the spray from the waves will break over the top, as shown near the end of the video.
Be sure to call Pier & Waterfront Solutions if you would like information about the design, permitting, or erosion control estimates.
At Pier & Waterfront Solutions, we provide a free site survey to determine the best material and design for your next dock.
