The Ultimate Seawall Inspections Guide (2024)

In this comprehensive guide to seawall inspections, we’ll examine these evaluations’ role in protecting your property and the surrounding area. We will explore the various types of inspections available, how often they should be performed, and the components of a seawall inspection. We’ll also explore the options for seawall repair and provide tips for maintaining your seawall to extend its lifespan.

What Are Seawall Inspections?

A seawall inspection comprehensively evaluates a seawall’s condition and structural integrity. A seawall inspection aims to identify any issues or problems with the seawall. Additionally, it helps determine the necessary repairs or maintenance to keep it in good working order.

Exploring the Different Types of Seawalls: Vertical, Curved, and Mound

Coastal erosion and wave damage can pose significant threats to properties and infrastructure located along the coastline. To protect against these hazards, many communities and coastal businesses have turned to seawalls as a solution. Seawalls are structures built along the shoreline that absorb the energy of incoming waves and prevent erosion. So, let’s look at the three main types of seawalls and understand them in depth.

Vertical Seawalls: A Solid Solution for Coastal Protection

A vertical seawall is a coastal defense structure that protects against erosion and wave damage. Professionals construct them by driving vertical pilings into the ground. Further, they attach a facing material, such as concrete or stone, to the front of the wall. The purpose of a vertical seawall is to absorb the energy of incoming waves and prevent them from eroding the shoreline. It also prevents causing damage to nearby structures. These seawalls are often used in areas with high wave energy and strong storms. They provide a more robust and effective form of protection than other seawalls.

However, they can be expensive to build and maintain. They may negatively impact the local ecosystem by disrupting the flow of sand and sediment. Despite these challenges, vertical seawalls are a common choice for coastal protection in many parts of the world.

Curved Seawalls: A Flexible Option for Coastal Defense

A curved seawall, also known as a revetment, is a coastal defense structure that shields against erosion and wave damage. It’s constructed by placing large, curved blocks or stones in series along the shoreline, creating a semi-circular or crescent-shaped structure.

The purpose of curved seawall is to absorb the energy of incoming waves and prevent them from eroding the shoreline. Also, prevent causing damage to nearby structures. Unlike a vertical seawall, which is a solid wall, a curved seawall allows water to flow through and around it. This reduces the impact of waves on the shoreline. This can be beneficial for the local ecosystem, as it allows for the natural flow of sand and sediment.

Additionally, curved seawalls are often more aesthetically pleasing than vertical seawalls. It’s because they blend in with the natural surroundings and do not block the view of the ocean. However, a limitation is that they may not be able to withstand strong storms, as well as other seawall types. In addition, the movement of the individual blocks may require more frequent maintenance to ensure the structure remains effective.

Mound Seawalls: A Natural Approach to Coastal Protection

A mound seawall, also known as a sand-filled seawall, is another coastal defense structure protecting against erosion and wave damage. Experts construct them by placing a large mound or embankment of sand along the shoreline. Then, they cover it with a protective layer of vegetation, such as grass or plants. The purpose of a mound seawall is to absorb the energy of incoming waves and prevent them from eroding the shoreline. Or, even cause damage to nearby structures.

A key benefit of a mound seawall is that it allows for the natural flow of sand and sediment. This can help to maintain the health of the local ecosystem. You may witness leveraging mound seawalls in conjunction with other coastal defenses like breakwaters or groins to protect against erosion. But they may not be suitable for steep slopes or cliffs.

The weight of sand and vegetation may not be sufficient to hold the structure in place on a steep slope. This leads to instability and potential failure. In addition, the construction of a mound seawall on a steep slope may be more difficult and costly. This is due to the challenging terrain. These factors may limit the use of mound seawalls in certain areas.

Materials to Leverage When Building a Seawall

The following are the most commonly in-use materials when building a seawall:

1. Concrete: Concrete is popular for seawalls because it is durable and long-lasting. However, installing it can be expensive and may not be the most aesthetically pleasing option.
2. Steel: Steel is another strong and durable material used to build seawalls. It is resistant to corrosion but can be more expensive to install than other materials.
3. Timber: Timber is a natural material that can be used to build seawalls. It is relatively inexpensive and easy to work with, but it may not be as durable as other options and may need to be replaced more frequently.
4. Stone: Stone is a natural material that can be used to build seawalls. It is durable and long-lasting, but it can be expensive to install and may not be the best choice in areas with high wave action.

When deciding on the material for a seawall, it’s important to consider the location, surroundings, budget, and desired appearance. It’s advisable to seek the advice of an engineer or contractor to identify the most suitable option for the specific project.

Some Common Seawall Inspection Types

Several types of seawall inspections may be performed, depending on the specific needs of the structure and the area it is protecting. Some common types include:

• Visual inspection: A visual inspection is a general evaluation of the seawall’s condition. During a visual inspection, the seawall examination provides for any visible signs of damage, such as cracks, erosion, or other defects.
• Structural inspection: A structural inspection is a more in-depth evaluation of the seawall’s condition, focusing on the structural integrity of the structure. This type of inspection may involve testing the seawall’s stability and strength and evaluating its foundation and materials.
• Elevation measurement: An elevation measurement estimates the seawall’s height and position relative to the waterline. This type of inspection is important for determining the effectiveness of the seawall in protecting against flooding and erosion.

Why Are Seawall Inspections Important?

These inspections are important for maintaining these vital protective structures’ structural integrity and effectiveness. Regular evaluations help identify potential seawall issues, allowing for timely repairs or maintenance. This is crucial for protecting your property and the surrounding area from damage caused by flooding or erosion.

Regular seawall inspections can catch problems before they become major issues, saving you money in the long run. Neglecting such inspections can lead to the seawall repair cost going through the roof down the line, as minor issues can quickly escalate into more significant problems if left unaddressed.

In addition to protecting your property, regular seawall inspections are also essential for maintaining the structural integrity of the seawall itself. Seawalls get constant exposure to the elements and can suffer from wear and tear over time. By performing regular evaluations, professionals can identify the potential issues and address them, helping to extend the lifespan of the seawall and ensure it continues to provide the necessary protection.

In short, a seawall inspection is essential for protecting your property, maintaining the structural integrity of the seawall, and saving money in the long run. Don’t wait until it’s too late – make sure to schedule regular inspections to keep your seawall in top condition.

How Often Should Seawall Inspections Be Done?

The frequency will depend on various factors, including the age of the seawall, the type of materials one leverages to make it, and the specific needs and conditions of the area it is protecting.

In general, it’s best to perform a seawall inspection at least once every three to five years. However, more frequent inspections may be necessary for older seawalls or those constructed with certain materials. For example, wood seawalls may require inspections every two years due to their susceptibility to decay and damage.

Other factors that may affect the frequency of such inspections include the level of exposure to the elements, the condition of the surrounding area, and any past issues or repairs that have been made. By considering these factors, you can determine the appropriate interval for seawall inspections to ensure your seawall is in good condition and provides the necessary protection.

It’s important to note that a seawall inspection is not just a good idea – it may also be required by law in some areas. For example, local building codes or zoning regulations may dictate the frequency of seawall inspections, so it’s essential to be aware of any applicable laws and regulations in your area.

Common Problems Found During Seawall Inspections

When inspecting a seawall, it is important to identify potential hazards that could lead to further damage or collapse. Common problems during seawall inspection include cracks, erosion, corrosion, and settling. Cracks can be the result of misalignment of the wall or due to the pressure of the water against the wall. Erosion could happen from water seeping into the wall and can weaken it over time. Corrosion possibly happens from moisture and salt air reacting with the metal components of the wall. Lastly, settling is caused by poor soil conditions that cause the wall to sink over time.

What Happens After Seawall Inspections?

Once the seawall inspection is complete, the inspector will provide an assessment of the wall’s condition. They may recommend repairs, maintenance, or even replacement, depending on their findings. If repairs are necessary, you’ll need to decide whether to do them yourself or hire a professional. If you choose to hire a professional, research their qualifications and experience before committing to any services and ask about the total seawall repair cost. Once the repairs take place, you can follow a few maintenance tips to ensure your seawall stays in good shape for years to come.
