Boat Dock Bulkheads serve to protect the shoreline from erosion and flooding. They also prevent damage to nearby structures. Bulkheads are designed to last 30+ years but require routine inspections to ensure deterioration doesn’t occur.
Inspecting a bulkhead involves examining its components, land and water conditions. The inspection process varies according to the type of bulkhead being inspected.
Steel sheet piles are a commonly used material for bulkheads. They have excellent strength characteristics for high wall exposure applications, interlock to form a watertight seal and can be driven in soft to medium soils. However, they can be susceptible to corrosion when exposed to the marine environment, particularly in warm climates. They should be protected from the elements with coatings and regular inspection and maintenance.
Sheet piles are generally made of corrugated steel, with aluminium sheet piles also available. They are used in a variety of projects including retaining walls, cofferdams, quay walls, manmade island seawalls and bulkhead walls for docks. Steel sheet piles are available in a range of sizes, shapes and grades. They are often used in conjunction with other types of seawalls and bulkheads, such as concrete walls or timber piers.
ESC Group offers a range of sheet pile profiles to meet the requirements of each project. The most popular is the Z-shaped sheet pile, which has good shear force transmission at the interlocks and offers a high strength to weight ratio.
Another type of sheet pile is the U-shaped section, which can be driven in a shallower depth than the Z-type. The U-shaped sections have a lower section modulus than the Z-type, which can help to reduce costs.
Cantilever or anchored wall: A cantilever bulkhead is typically designed for a retained soil height of up to 6 meters. It has the advantage of a minimum of property encroachment and interference with adjacent structures. An anchored wall can accommodate greater retained heights, but requires more anchorage and is less flexible than a cantilever wall.
If your existing bulkhead is damaged or deteriorating, it’s important to undertake a detailed assessment of the structure before making any repairs. The evaluation should include an investigation of the existing seawall or bulkhead, site conditions and use, soil analysis, scour potential, currents, wave action and the anchorage system.
Repairs to existing seawalls or bulkheads can be costly, but it is possible to reduce future repair costs by upgrading the original design to incorporate modern materials that are longer lasting and more corrosion resistant. This can be achieved by using a system like the SPiRe bulkhead repair. This uses lightweight FRP panels that are fabricated near the jobsite to match the shape of the existing seawall or bulkhead being repaired.
Wood
A bulkhead is a structure that decelerates erosion and flooding of waterfront properties. It also helps to create more usable space on the property and can serve as a barrier between your dock and the water. Because Charleston’s coastal area is so fragile, the material that you choose for your bulkhead must be able to withstand constant onslaught of elements.
Wood is a popular choice for building boat docks because it’s relatively affordable and has good aesthetic appeal. However, it can be vulnerable to marine borers and rot and requires regular maintenance in order to keep it safe from the elements. Fortunately, there are several options available for wood bulkheads that will provide you with the durability and longevity you require.
The most common and inexpensive option for a wood bulkhead is pressure-treated southern yellow pine. This type of wood has been treated with chemicals that increase its resistance to rot, parasites and fungi, as well as making it stronger and more durable. It can last a couple of decades, especially if it is regularly maintained with waterproof sealants and staining.
Composite materials are also a great choice for constructing a bulkhead. They are highly resistant to rot, pests and disease and are more resilient against harsh weather conditions than natural wood. They are also more resistant to UV rays, meaning that they will not deteriorate as easily as natural wood.
Another advantage of composites is that they are much easier to work with than natural wood. They can be shaped and cut with the use of power tools, allowing you to achieve a more custom look. Composites also come in a range of colors and textures, which makes them ideal for homeowners who want to build a bulkhead that complements their surrounding scenery and personal style.
Regardless of which type of bulkhead you choose, it’s important to consult with local laws and regulations regarding construction of bulkheads in your area. Some states, including Alabama, require you to obtain a permit before starting any project that may impact coastal resources. This includes constructing new seawalls or bulkheads, and even repairing existing ones.
Vinyl
In marine construction, there are several different materials that can be used to construct bulkheads and seawalls. Each material has its advantages and disadvantages. A marine construction expert can help you choose the best option for your project. There are many factors to consider, including the budget and how long you want your wall to last.
Vinyl bulkheads are a popular choice for people who own waterfront property. They are durable and require little maintenance. They also have a modern look that adds to the beauty of your waterfront. They are also resistant to rot, bug infestation, and saltwater damage. This makes them a cost-effective alternative to other materials, such as wood or concrete.
There are three main types of bulkheads and seawalls: timber, vinyl and stone. Timber is a classic option that works well in coastal areas. It is typically constructed with 2.5 CCA treated lumber and can be backfilled with fill dirt or sand. Wooden bulkheads can also be made with recycled plastic lumber or commercially developed vinyl products. They are usually designed to slow large landslide erosion caused by wave action.
Vinyl is a new technology in marine construction that offers several benefits over traditional materials like wood and steel. It is durable and long-lasting, and it can be easily adapted to your specific needs. It is also resistant to chemicals, mildew and marine borers, making it a great choice for your seawall or bulkhead.
Marine construction contractors use vinyl sheet piles to build a variety of marine structures, including retaining walls in marinas and coastal erosion protection. They are also frequently used to construct seawalls, piers, revetments, and cofferdams. They are highly resistant to corrosion and other environmental conditions, so they can be easily adapted to your specific project. Vinyl is an environmentally sustainable alternative to other marine construction materials, such as wood and steel, because it doesn’t leach chemicals into the environment. In addition, it is lighter and easier to install than other materials. This allows contractors to complete projects faster and more efficiently. It is a safe, cost-effective, and durable solution for all of your marine construction projects.
Aluminum
Bulkheads are a critical component of any marine construction project. They can prevent erosion, flood damage, and provide stability to adjacent structures like seawalls or docks. They can also be constructed from a variety of materials, including wood, vinyl, steel and aluminum. The best material for a bulkhead depends on how long it is expected to last and the environment where it will be placed. It is important to work with a professional who can determine the right type of bulkhead for your needs and budget.

A bulkhead is a structural element that forms a diaphragm or wall. It is usually made from a durable material such as concrete, vinyl or steel and may be designed to accommodate various loading conditions. The design of a bulkhead should take into account the wind load, hydrostatic pressures and any surcharges. It should also be engineered to withstand the full applied load.
Generally, bulkheads are constructed from piles of wood or concrete. However, the most common material is CCA (Chemically Treated Lumber or Pilings). These are pressure-impregnated with a preservative to make them resistant to marine borers and fungi that cause decay. However, these chemicals have been shown to be dangerous to the environment and are being phased out in many areas. As a result, some marina owners are looking for alternative options for their bulkheads.
Aluminum sheet piles are an excellent choice for bulkheads because they have a high strength-to-weight ratio, are easy to install and are corrosion resistant. They are available as interlocking corrugated sections in a variety of alloys and can be used in fresh or salt water. They can also be fabricated into a number of different shapes and lengths, and are ideal for deepwater applications.
