What Are the Three Types of Seawalls?

There are three main types of seawalls: riprap, cobblestone, and concrete. Each one comes with its own advantages and disadvantages, so it’s important to choose the right type for your needs.

Riprap Embankments

This cost-effective seawall is a good choice for areas with low-impact waves. It consists of a mound made from rubble and rocks, which is then covered in stone or sandbags. This creates a barrier that reduces wave impact and protects property.

Outcropping

Another type of seawall uses rocks that are stacked in an aesthetically pleasing fashion. They are usually large and irregularly shaped, giving them a unique look. They are often accompanied by grasses and other natural vegetation that helps them integrate into the natural environment.

Curved Seawalls

These walls are designed to dissipate wave energy and lessen the effects of turbulence. They also prevent erosion, help control sediment movement, and protect against flooding.

The curved shape of the wall helps to reflect the wave energy back towards the ocean, which decreases the power of the waves. This can also keep the water from overtopping the wall, which is a common problem with vertical seawalls.

Construction

It takes time and effort to construct these types of seawalls. Before you can start, you’ll need to excavate the area where you want to build your structure. Then, you’ll need to install pilings that will help support the wall.

A curved wall requires a lot of space and work, so it isn’t ideal for every beach. The curved design can also make the wall more difficult to maintain and repair, especially if the waves are strong or heavy.

Outcropping is also a popular option for beaches. It can be extremely aesthetically pleasing, and is easy to install.

However, the stones used in this style of seawall can be expensive and require a lot of maintenance to maintain their shape and integrity. They are also more likely to rot than other types of wall, which can lead to termites and other problems.

Concrete Seawalls

A popular option for properties that are prone to frequent and powerful waves, a concrete seawall is durable, low-maintenance, and easy to install. It can also be a great option for beachfront properties that experience a high volume of storms.

If you’re looking for a more aesthetically-pleasing option, you might consider a cobblestone seawall. These are made from large rocks and boulders that are piled up into a decorative form.

These are an excellent choice for beachfront properties that see moderate to light wave action, but they aren’t suitable for every body of water. You’ll need to consider the size and depth of your lake or river to find a seawall that will work best for you.

The type of materials you use in the construction will also affect its lifespan. A seawall made from wood might be cheaper to install, but it’s less durable than a steel or concrete wall.

Choosing the right seawall for your needs is an essential part of protecting your property from flooding and soil erosion. It can also ensure that your home or business stays safe from a wide range of weather conditions, including heavy rain, snow, and ice storms.
