Dock height and layout

When determining the height of your boat dock, it is important to balance accessibility with avoiding excessive submergence. You need to ensure that enough of the dock remains above the water level to withstand general wear and tear, while still allowing easy access to your boat and enabling activities like fishing.

As a rule of thumb, position the bottom beams a few inches above the highest potential waterline. Take into account factors such as fluctuating water levels due to rainfall or seasonal changes. For lakes, you can identify this by locating runoff points, which are typically placed at maximum lake levels. For smaller bodies of water, historical records or natural stone outcroppings can give insights into past high-water marks.

The water depth is a crucial factor in determining the type of dock you need and how it will be anchored. Shallow waters are best suited for fixed docks with pilings, while deeper waters may require floating docks that can adjust to changing water levels. Consider any variations in the lake or river bottom to ensure proper construction and stability for the safe mooring of your vessel.

If you are in an area with fluctuating water levels, a floating dock system is an excellent option. This type of dock can adapt to changing water levels, preventing damage and ensuring your dock remains safe and functional.

If you are considering a permanent dock made from materials such as galvanized steel or pressure-treated wood, check local regulations first as there may be specific guidelines in place. Permanent docks are fixed structures built on pilings driven into the lake or river bottom and are ideal for areas with consistent water levels.

Hybrid docks combine the benefits of both floating and permanent docks. They are partially submerged in water and rest on supporting poles or pilings driven into the lake bottom, offering stability and durability in areas with fluctuating water levels or moderate wave action.

Dock foundation

The foundation of your boat dock is critical to its strength and durability. When constructing a dock foundation, sinking wooden posts directly into the seabed may not provide the best stability. For a sturdier option, consider using PVC pipes filled with concrete as footers.

PVC pipes, either 12-inch or 18-inch in diameter, can effectively support the structure of your dock. Ensure that the pipe extends several inches above the water level to prevent any exposed wood from submerging. For added stability, sink the PVC pipe at least three feet into the bed using a post-hole digger.

Once the PVC pipes are secured in place at the desired depth, pour concrete around each post inside its designated PVC sleeve. Allow ample time for the concrete to cure before trimming any excess height from the posts. Now you have firmly attached 8- to 10-foot-long treated lumber posts that will support your dock.

Choosing the Right Materials

The choice of materials for your dock foundation is essential to ensure its longevity. Treated wood is a popular option for dock construction due to its affordability and availability. However, all types of wood are susceptible to issues like splintering, rotting, and warping over time, requiring regular maintenance.

Composite decking, made from a blend of wood fiber and plastics, offers durability and reduced maintenance. On the other hand, metal options like aluminum or steel provide excellent strength but may have their own considerations, such as maintenance or installation challenges.

PVC (polyvinyl chloride) decking is an excellent choice for its lightweight composition, easy maintenance, and resistance to rotting and splintering. Additionally, PVC decks maintain cool temperatures even in hot weather.

Piling Foundations

Piled foundations are deep-set foundations formed from long, column-like structures made of steel, concrete, or timber, driven into the ground. For a dock foundation sitting in water, piling is crucial as the surrounding soil may not provide sufficient support. A deep-set foundation is necessary to prevent excessive settlement.

Driven piling is an effective engineering solution for dock foundations. Driven piles are relatively easy to install as they displace the soil, providing additional support and strength. They are also cost-effective and save time compared to other foundation methods.

To ensure the longevity of your piling, it is essential to protect it from deterioration. Apply a pile sleeve, typically made from PVC, to your piling before setting it on the ground. This protection will significantly extend the lifespan of your piling while reducing environmental impact.

Dock decking

When it comes to dock decking, there are several options to choose from, each with its own advantages and disadvantages. Here is a detailed guide to help you select the best decking material for your DIY boat dock:

Wood Decking

Wood is a popular choice for dock decking due to its affordability and widespread availability. Pressure-treated wood, in particular, is commonly used as it tends to remain cool to the touch, even in bright sunlight. However, wood requires regular maintenance as it is prone to issues such as splintering, rotting, and warping over time. All types of wood will eventually rot when exposed to the elements, and it can become slippery when wet. Modified wood boards can be used to construct dock planking and benches, providing a cost-effective and durable option compared to purchasing expensive furniture.

Composite Decking

Composite decking is made from a blend of materials such as wood fibre and plastics. It offers durability and requires minimal maintenance compared to traditional wooden docks. Composite decking can last 25 to 30 years and is environmentally friendly. However, organic components within composite materials may make it vulnerable to mould or mildew growth. Composite decking is more expensive than wood but is available in a variety of colours and textures that mimic the look of real wood.

Metal Decking

Metal options for dock decking include aluminium and steel. Aluminium is lightweight, strong, and corrosion-resistant. It requires less maintenance than wood but can get hot under direct sunlight. Steel, on the other hand, offers superior durability and strength but may be more challenging to install. Steel is extremely heavy and will rust over time unless treated. Metal decking products, including aluminium, can be expensive and may be hot to the touch on sunny days.

PVC Decking

PVC (polyvinyl chloride) decking is an excellent choice for those seeking exceptional resistance to moisture-related problems such as mould or mildew growth. PVC decks are lightweight, easy to maintain, and do not rot or splinter easily. They also maintain cool temperatures even during hot weather. Trusscore's DockDeck is an example of a PVC decking product that is designed to handle harsh environmental conditions. It has low heat retention and a unique open-cavity profile, and is available in a variety of colours and slip-resistant textures.

When choosing the best decking material for your DIY boat dock, consider factors such as maintenance requirements, durability, cost, and environmental conditions. Additionally, ensure that your decking choice complies with local regulations and is suitable for the intended use of your dock.

Dock types

There are two main types of boat docks: fixed and removable. Here is a closer look at some of the most popular options within these categories:

Fixed Docks

Fixed docks, also known as stationary or permanent docks, are ideal for shorelines with minimal fluctuations in water height. They are securely anchored to the shoreline or have pilings driven into the waterbed.

Pile Docks

Pile docks are sturdy structures supported by driven pilings, typically made of wood, steel, or concrete. They provide exceptional stability and can bear significant weight. The foundation is commonly made of steel or concrete for stability, while the top level can be wood for a more pleasing aesthetic.

Crib Docks

Crib docks are constructed with wooden frames filled with rocks or gravel. They offer stability and a more rustic aesthetic but do not allow for easy water movement, which can create marine habitat issues. Some places ban these docks due to their adverse effects on wildlife and water flow.

Fixed Sectional Docks

These dock systems consist of interconnected sections anchored to the shore using posts or legs. They are ideal for shallow water or uneven shorelines, offering unparalleled versatility and customization.

Removable Docks

Removable docks are practical for areas with fluctuating water levels or deep waters where installing fixed docks is not feasible.

Floating Docks

Floating docks are connected to the land but float on the water using airtight drums. The materials range from buoyant foam, plastic, or a combination of these with wood. They are removable, relatively inexpensive, and easy to install.

Pipe Docks

Pipe docks are similar to piling docks but use aluminum poles instead of steel or wood. They are removable, which is beneficial in cold climates, but are less sturdy and only work in water less than 12 feet deep.

Lift-Up Docks

Lift-up docks have a sturdy galvanized steel frame and a lift function to protect them from cold weather damage.

Hybrid Docks

Hybrid docks combine the benefits of floating and permanent docks. They are partially submerged in water while also resting on supporting poles or pilings. This design offers stability and durability, making it ideal for fluctuating water levels or moderate wave action.
