Boat Dock Bulkheads
Boat Dock Bulkheads Charleston SC are a vital part of waterfront property. They serve many purposes, from protecting the land to creating water depths for boats. They can also be a great place to moor your boat.
Pile, panel, and concrete pile or block walls may have a life span of 30+ years. A variety of materials are used for their construction.
When you own waterfront property, erosion is a common problem that can destroy your home or marina. Waterfront bulkheads protect the shoreline by retaining the soil, and they also give you more water depth right at the edge of your property. This prevents erosion from occurring on your property and carrying dirt into the water, which would damage your dock and your boat.
In addition, waterfront bulkheads help outline where your property begins and ends. This prevents land disputes with your neighbors, and it keeps erosion that occurs on their property from affecting yours. A quality bulkhead can last decades and is a worthwhile investment for your home or marina.
Bulkheads are often confused with seawalls, but they have different purposes. The main difference is that bulkheads are designed to retain soil, while seawalls protect upland areas from wave action. In general, a marine construction company will design a bulkhead that best suits your property.
Both bulkheads and seawalls slow erosion by limiting the force of pounding waves on the shoreline. They are an important component of the armoring of the coastline and can be made from a variety of materials, including wood, steel, aluminum, vinyl, or concrete. Marine construction companies on the Florida Gulf Coast will be able to discuss the advantages of each type of bulkhead and assist you in selecting the best one for your needs.
Regardless of the type of material, bulkheads need to be properly maintained to ensure that they are functioning correctly. If you are using a wood bulkhead, it should be treated or painted periodically to keep the wood from becoming rotted and damaged. If you have a steel or aluminum bulkhead, it should be galvanized to prevent corrosion and protect the metal from the elements.
The walers on a bulkhead are another critical piece of the structure that should be inspected regularly for signs of damage or deterioration. These rods are used to anchor the sheeting and hold it in place. It is important to replace these woods if they become damaged or rotten.
They create water depth along the shoreline.
Bulkheads are primarily designed to retain soil and help control the erosion of the surrounding shoreline. This helps preserve property values and protect boats and other marine structures, such as piers. Bulkheads are constructed from a variety of materials. Pricing for each type depends on the number of linear feet needed. The cheapest types of bulkheads are constructed from concrete. These are usually poured-in-place, but precast concrete slabs or a combination of poured-in-place and precast slabs may also be used. The most expensive types of bulkheads are often made from steel or concrete pilings driven into the ground. These are then anchored at the back with a “dead man” piling installed behind each one. A helical tie rod is then attached to the dead men and runs back to a concrete deck at the water’s edge.
A deteriorated bulkhead is an indication that it has been subjected to loads in excess of those it was designed to withstand. It may also be a sign that the structure has reached the end of its service life. In either case, it is important to have a qualified marine engineer evaluate the bulkhead and make recommendations for repair or replacement options.
Unlike seawalls, which are meant to contain and stabilize the soil, bulkheads primarily retain soil, but they are also engineered to resist wave overtopping and the erosion of the adjacent coastline. The design of a bulkhead is generally based on a soil analysis, site conditions, and a review of the water conditions to be expected at the location.
In addition to the concrete panels themselves, there are several other components that add strength and stability to a bulkhead. On the upland side, the top of the seawall is typically covered with a reinforced concrete cap to prevent erosion from the sides and bottom. On the water side of the panel, there are often “weep holes” drilled to facilitate efficient drainage and prevent the buildup of hydrostatic pressure that could cause the structure to collapse. Finally, on the toe of the bulkhead, there is often a berm or area of earth that is reinforced with riprap to promote stability and support the toe of the panel.
They are often used as mooring places for boats.
A bulkhead is a great mooring place for boats because it protects them from severe storm surges, pounding surf, and eroding shorelines. It also creates water depths along the coastline, and it can be used to extend a dock or gangway into the water. Bulkheads are commonly found at marinas, and they can also be a source of revenue for marina customers.
One big benefit of mooring your boat alongside a bulkhead is that it’s easy to access. It’s easy to get in and out of the boat, and there are usually hookups for water and power nearby.
However, there are some drawbacks to mooring a boat alongside a bulkhead. First, you may experience some swaying during a strong squall. This can be annoying, especially if you are trying to sleep. Second, being tied up close to a bulkhead can leave your boat vulnerable to thieves or vandals who may try to climb aboard. It’s a good idea to install some high-visibility fenders that will make it hard for anyone to climb aboard the boat and to keep anything valuable out of sight from possible vandals or thieves.
Another problem with being tied up alongside a bulkhead is that you will not be protected from the wind, which can cause a lot of spray. This can make it harder to enjoy your time on the boat, and it’s important to have some good-quality fenders that will help reduce the spray from the waves.
Finally, it’s a good idea to have some high-density spring lines that are made of a material such as polyester, which can withstand greater loads than nylon and will not stretch as much. This will help to reduce fender loads, and it will also minimize the likelihood of your fenders pushing out of place during a strong squall.
Bulkheads are a common sight in coastal areas, and they serve many vital purposes for the people who live there and visit there regularly. Marine construction companies such as RG Murphy can install bulkheads for residential and commercial clients, and they offer a wide selection of construction specifications.
They are often used as gangways.
Bulkheads are often used as the base for docks or as access routes to a boat’s mooring. In these cases, they are also called “gangways.” They must be strong enough to withstand the weight of boats, equipment, and people. They must also be designed to allow for easy passage and navigation.
A proper bulkhead condition study should be completed on a regular basis to extend the service life of the structure. The analysis should include both above- and below-water inspections as well as a comparison of the results from previous reports. This information will help marina management plan for the cost of repairs or replacements and understand when the bulkhead is nearing the end of its useful life.
Typically, a marine construction project requires a permit from the environmental resource agency and the building department. The excavation and installation of a bulkhead should be done by a licensed professional engineer. The underlying waterway needs to be stabilized as well, which can be done by dredging.
There are many factors that go into the design of a bulkhead. The type of material to use and the method of construction can influence the overall cost. Some types of materials are more durable than others, and some are better suited for certain environments. The local weather conditions can also have a major impact on the performance of the bulkhead.
The construction of a bulkhead will require pilings for support and a sheet pile that is meshed or interlocked to form a diaphragm or wall. In some cases, a concrete or poured-in-place bulkhead may be required. For other projects, a steel sheet pile or a concrete-and-wood composite may be suitable. The components and hardware should be galvanized or protected from corrosion with coatings and cathodic protection.
A bulkhead not only protects the shoreline and provides an economical interface between upland and wet slips, but it can also be a source of revenue for the marina. In addition, the construction of a bulkhead can help with the maintenance of the wet slips and the upland docks that are attached to them.
