![]() It’s too soon to tell what 2021 will mean for water levels. They had plenty of water even with a shorter dock. As a result, many people decided not to install all the sections. What to look forward to in 2021Ģ017-2020 saw high water after years of decline in water depth. Less chance of the dock being “lifted” or rolled over. With 42% less deck surface, they allow the wave to pass through the decking and minimizes the pressure from the waves. The “Flow-Through” decking, which is standard on the 3-Season Pier, reduces the effect of the waves on the dock. We recommend the open style of decking to minimize vertical dock movement. Both of these have virtually no strength and should never be used on a dock.) One final suggestion (Compare that with the legs used by some competitors – 1 1/4 pipes or 1 1/2″ tubing. The new pier uses 2″ schedule 40, steel pipe, which is approximately 2 3/8″ O.D. What does PWS do on the new 3-Season Pier? For the structure to move sideways, it must also move the opposite leg at the base where it is firm. One end is near the bottom and the other end is under the frames and near the top of another leg. What are cross braces? They are pipe(s) attached at an angle to the legs of the dock. Cross braces will eliminate, or at the very least, cut down on the swaying. The only thing that we can do is to add cross-braces. Place your feet on the top of the ladder, and it’s precarious. Think of it this way – If you are on a 6 – step ladder, the first few rungs are stable. The pier is now less stable because the center of gravity is higher. When you experience high water, we must raise the dock to minimize damage during storms.Īt the same time, increasing the dock height brings a problem with it. The height determines how much sway you experience.īy raising the dock, the center of gravity is elevated. What if the movement is side-to-side (sway)?ĭock “sway” results when a dock is raised high out of the water. When the dock frame goes up, it takes the legs with it, allowing the wave to move the rocks around under it. If a wave makes contact with the bottom of any solid decking, it will push the dock up – momentarily. Once the stones move away from the leg, the leg has nothing supporting it. Like the sand beach, a storm may “wash out” smaller rocks under the footpads. The next storm could leave the same leg pad buried under 6″ of sand. There is no way to prevent this from happening. Even with a properly installed dock, a storm can move the sand at any time. It is not uncommon for storms to “wash out” the sand from under the footpads. Try to “wiggle” the legs around and re-tighten the bolts, if needed. Now, push up on the dock frame and tighten one bolt and then the second bolt. When you loosen the bolts, the legs will fall until the footpads hit bottom. While standing in the water, loosen both bolts on only the affected leg. If this is the case, the legs need adjustment. If you are in a sandy area, the water may have washed the sand out from under the footpads. ![]() It’s rare, but occasionally one of them is not touching the bottom. If the bolts are tight on the dock legs, the problem is at the bottom of the legs. Are the bolts loose in the affected area? The simplest way to check for the cause is to check the bolts that lock the legs. The problem should affect only one side of the dock. Usually, you will sense the bounce in one area along the dock length. Loose bolts on the dock frame in the leg pockets. A leg is no longer in contact with the lake bottom orĢ. VERTICAL MOVEMENT (BOUNCE) HAS TWO POSSIBLE CAUSES:ġ. As you may have noticed, the sensation is more noticeable when you walk near a dock leg. Vertical movement gives you a “spongy” bounce as you walk on the deck. ![]() These have different symptoms, and both have different solutions. ![]() But, we need to distinguish between vertical movement and horizontal movement. HOW CAN THE MOVEMENT BE MINIMIZED?īefore we can answer that question, there’s an important question you must answer. Due to the deep water and stronger storms, it is necessary to raise your dock to protect your equipment. Movement or ” dock sway” is the result of deeper water. ![]()
