It is vital to remember the importance of constructing sea walls next to your coastal home. Generally, climate change is one of the most severe topics in the 21st century.
One of the most significant consequences of climate change is increased sea levels. Since it comes with side effects on the environment across the globe, you should be serious about it and try to prevent it from affecting you. We recommend you click here to learn everything about seawall construction.
A rise in water levels can lead to an increase in tides and waves. At the same time, the necessity of the creation of shields on the shoreline is increasing. Throughout this guide, we will present numerous benefits and downsides of seawalls that will help you understand each step.
What are Seawalls?
You probably understand that coastal regions come with numerous attractions, including trade, fishing, tourism, and transport. That is why numerous coastal management strategies are preserving the coastline. The walls are part of protection measures constructed on coastlines, and you should understand the importance of their creation and operations.
People used them for thousands of years, while the early ones were in Constantinople, protecting the city from the damaging effects. It means they are critical, and some are still transparent and usable. Therefore, we must understand them before talking about the benefits and downsides.
A seawall is a system of coastal defense you must construct parallel to a coastline. The main goal is to protect the land from erosion caused by waves. At the same time, it can shield households and people from the adverse effects of tides, waves, tsunamis, and hurricanes.
Since they are stationary, they conflict with dynamical coastal nature, preventing sediment exchange between land and sea. The physical design is variable, which can be vertical or sloping and feature many materials. They are perfect in regions where shoreline erosion can cause severe damage.

You can find various types of seawalls coming from brick, concrete barriers, rubble mount structures, steel sheet piles, and many more. They also range in type, size, and materials used for the process. Of course, they require more permanent construction, which is expensive to design and build.
Remember, they require proper design and supervision, which will prevent potential issues from happening. Seawalls can protect the shoreline from erosion caused by waves, meaning they should be sturdy enough to handle them easily.
Texture and design also come with a significant impact on performance. For instance, the smooth surface will reflect the wave energy, while the irregular surface will disperse its direction. In most cases, they feature a deep foundation to enhance stability. You can also add earth anchors into the land and connect it with rods to ensure it can withstand the pressure.
Benefits
You can find numerous professionals who can make the perfect solution to flooding and erosion issues. It is a long-term solution, meaning you will experience certain advantages, such as:
- Protection – The first and most important benefit is the additional protection you will get against flooding from waves and coastal erosion, which is mentioned above. You can use waves as renewable energy sources instead of a destructive force.
- Static Barrier – At the same time, the seawalls for the static barrier, meaning you will get a frontier between land and water.
- Space Friendly – Compared with other coastal defense options such as dikes, seawalls do not require too much space for the construction. Since they are vertical, while others can be horizontal, you will save space overall.
- Durable – Remember that they are highly durable and long-term options to prevent shoreline erosion. They are better than soft beach nourishments, which is vital to remember.
- Flexible – You should know they are highly flexible regarding modifications and adjustments. Since the sea can feature different levels of threats that require effective defense, you can update them to meet the requirements. Besides, climate change discovery means you can upgrade it to assess more problems than before.
- Less Expensive – Since the land in coastal regions is prevalent, the construction will require area and less space than other options available on the market. That will translate into a more affordable option.

- Security – Another critical factor is the increase in security, which will provide you an additional safety so you can promote investments in a particular coastline without considering specific consequences.
- High Amenity Value – You can implement a wide array of designs to increase overall value. At the same time, you can incorporate promenades that can become attractions and promote tourism and recreation.
- Durable – With proper maintenance, the seawalls are highly durable. For instance, the one constructed in Galveston, Texas, in 1903 is still adequate protection against city flooding and erosion.
Disadvantages
Although they come with many benefits, you should know that we can differentiate specific cons you should remember.
- Expensive Construction and Maintenance – Everything depends on your preferences, but having a coastal household requires a seawall. Still, it is not as affordable as other options, but you must protect yourself, which is why it is indispensable.

- Curved Walls are Not Effective – For instance, constructing a curved wall will reflect the wave’s energy to the ocean. It means the waves will maintain their strength, while the wall will start eroding as time goes by. Since most coastal lines are attractions, it can reduce the area’s popularity when a specific one is unappealing.
