Seawalls – What Are They?

If you’ve ever been to the beach, you’ve likely heard of something called a seawall. Individuals that have lived along the coast, or visited these areas, know a bit about seawalls but not much. What are these walls beneath the ocean’s waves and how do they impact your life? Professionals in marine construction services have answered these questions to make the sea just a bit less mysterious.

What’s A Seawall?

Seawalls are sort of like a defense system for the shore. They work by minimizing the amount of erosion that takes place when waves crash against the shore. They also lessen the amount of energy that waves have when they reach the land, making it safer for inhabitants of the area and reducing the amount of damage done over time. Seawalls can either be vertical or riprap embankments.

Vertical

Seawalls that are vertical are the easier of the two to build. They protect the coast with their strong walls and keep waves from reaching their maximum strength when they make contact with the shoreline. Some walls may be further improved by the installation of piles, which are placed in front of the wall.

Embankments

Riprap embankments are often used for areas that do not receive heavy waves as much as other beaches. They are used to break up the energy that is present in small waves, reducing erosion and keeping the coastline intact. These can’t withstand heavy waves, but they’re cost-effective.

Depending on the area you are in, a seawall may be recommended. On your next visit to the beach, look out into the water and try to look for a seawall. With this information, you can have a better understanding of what goes into making sure that you and your loved ones are safe while on the shore and in the water.
