When you install dock posts in water a crucial step is to build it in a sturdy and reliable dock. Whether you’re constructing a new dock or replacing existing posts, proper installation ensures the stability and longevity of your structure. In this guide, we will walk you through installing dock posts in the water, providing you with the steps and tips for a successful installation.

What Is A Dock Piling?

A dock piling is a vertical structural element that provides support and stability to a dock or pier. It is typically made of solid and durable materials such as wood, steel, or concrete. Dock pilings are driven or installed into the ground, usually submerged in water, to anchor the dock and provide resistance against various forces such as waves, currents, and loads from boats and people.

Dock pilings come in various shapes and sizes depending on the specific requirements of the dock structure and the environmental conditions. They can be cylindrical, square, or rectangular in shape and are available in different lengths and diameters to accommodate the intended use and load capacity of the dock.

Step 1: Gather the Required Tools and Materials

Before you start to install dock posts in water, you may need to gather all the necessary tools and materials. These typically include:

  • Dock posts: Choose posts made from durable materials such as steel, aluminum, or treated wood that can withstand water exposure.
  • Concrete footers: Pre-cast concrete footers or individual concrete bags are commonly used to secure the posts in place.
  • Water-resistant hardware: Galvanized or stainless steel bolts, brackets, and screws are ideal for connecting the dock posts.
  • Level: Ensure you have a reliable level to ensure the posts are straight and plumb.
  • Measuring tape: Use a measuring tape to ensure accurate positioning and spacing of the dock posts.
  • Power drill or screwdriver: Required for fastening the hardware.
  • Shovel or auger: Use a shovel or auger to dig holes for the concrete footers.
  • Safety gear: Don’t forget to wear safety glasses, gloves, and appropriate footwear throughout the installation process.

Step 2: Determine the Placement and Spacing of Dock Posts

Before you install the dock posts in the water, carefully plan the placement and spacing to ensure the stability and functionality of your dock. Factors to consider include water depth, local regulations, and the size of your dock. Typically, posts should be spaced around 4 to 8 feet apart, depending on the size of the dock and the anticipated load.

Step 3: Dig the Holes for Concrete Footers

Using a shovel or auger, dig holes in the water where you need to install the dock posts. The depth of the holes should be based on local regulations and the desired stability of the dock. Typically, we recommend a depth of at least 1/3 of the post height.

Step 4: Insert and Level the Dock Posts

Place the dock posts into the holes and ensure they are straight and plumb using a level. Make any necessary adjustments to achieve the desired positioning. You may need assistance to hold the posts in place while you proceed with the next steps.

Step 5: Secure the Dock Posts with Concrete Footers

Once you install the dock posts in water and you are properly level them, pour the concrete footers into the holes around the posts. Follow the manufacturer’s instructions for mixing and pouring the concrete. Ensure that the footers are well-packed and reach the desired height above the waterline. Smooth the concrete surface and allow it to cure according to the manufacturer’s recommendations.

Step 6: Attach Brackets and Secure the Dock Structure

After the concrete footers have cured, attach brackets or hardware to the dock posts for connecting the dock structure. Use galvanized or stainless steel bolts, brackets, or screws to ensure resistance to corrosion and water damage. Securely fasten the dock sections to the posts, following the manufacturer’s instructions.

Step 7: Perform Final Checks and Adjustments

Once the dock structure is securely attached to the dock posts, perform a final check to ensure everything is properly aligned, level, and stable. Make any necessary adjustments to ensure the dock posts is safe and functional after you install them in the water.

Additional Protection for Dock Pilings

Dock piling wrap, dock piling caps, and SnapJackets are essential components for the maintenance and protection of concrete dock pilings. By investing in these protective measures, you can enhance the durability, longevity, and performance of your dock posts after you install them in the water, ensuring safe and enjoyable experiences for years to come.

Dock Piling Wrap

Dock piling wrap, also known as piling wrap sleeve, is a protective covering specifically designed for dock pilings. It is typically made of durable materials such as high-density polyethylene (HDPE) or fiberglass. The wrap is wrapped around the concrete or wooden pilings, creating a barrier that helps prevent water infiltration, corrosion, and damage from marine organisms.

Dock piling wrap serves as a protective layer between the piling and the harsh marine environment. It shields the pilings from the corrosive effects of saltwater, chemicals, and UV radiation. Additionally, it helps deter the attachment of marine organisms such as barnacles, teredos, and algae, reducing the risk of biofouling and prolonging the lifespan of the pilings.

Dock Piling Cap

A dock piling cap is a protective covering that is placed on top of dock pilings. It is designed to provide an extra layer of defense against the elements and physical damage, prolonging the life of the pilings and maintaining the integrity of the dock structure.

The primary function of a dock piling cap is to shield the top of the piling from moisture, rain, and other environmental factors. It helps prevent water from seeping into the dock posts when you install them. Water seepage can lead to rotting, decay, and weakening of the structure over time. By keeping the top of the piling dry, the cap helps preserve its strength and structural integrity.

Concrete SnapJacket

A SnapJacket is a type of protective sleeve or covers designed specifically for concrete dock pilings. It serves as a barrier between the piling and the surrounding environment, providing an additional layer of defense against corrosion, impact, and other forms of damage.

SnapJackets are typically made from durable materials such as high-density polyethylene (HDPE) or PVC. They are designed to be lightweight, yet strong enough to withstand the harsh marine conditions and the weight and movement of boats or vessels that may come into contact with the dock pilings.

The main purpose of SnapJackets is to protect the concrete pilings from the corrosive effects of saltwater, as well as other damaging elements such as marine organisms, UV radiation, and impact from floating debris. These factors can cause deterioration and weakening of the concrete over time, leading to structural issues and potential safety hazards.
