That’s why choosing the right erosion-control structure is essential. Two of the most common solutions, breakwaters and seawalls, are often confused, but they work very differently. While both structures are designed to manage wave activity near the shore, only one effectively protects your coastal property from long-term erosion. Let's take a closer look at these two types of marine construction.

A breakwater is built along the shoreline, extending into the sea or standing independently. Typically made of rocks or concrete, it forms a wall, or submerged barrier, parallel to the shore. This barrier breaks the wave and reduces its impact on the shore. Breakwaters are typically installed in small harbors to shield boats from the open sea while they dock.   ![idan-levi-IYkXSjgIi1o-unsplash](https://blog.duncanseawall.com/hs-fs/hubfs/idan-levi-IYkXSjgIi1o-unsplash.jpg?width=900&height=506&name=idan-levi-IYkXSjgIi1o-unsplash.jpg)     ## Can Breakwaters Protect My Waterfront Property from Erosion? Breakwaters used to be constructed on beaches and shorelines to protect them from erosion until marine contractors found that they heavily depleted the sand and sediment from their immediate and wider surrounding areas. So, the short answer is no.   Unfortunately, [the breakwaters caused a great deal more in erosion damage expenses](https://www.sciencedirect.com/science/article/pii/S2405844022039147) than the original cost of constructing them. Nowadays, knowing that breakwaters actually create additional erosion to their surrounding areas, they are typically only used to protect boats as they dock.   ![expanalog-2jwBANCu4_I-unsplash](https://blog.duncanseawall.com/hs-fs/hubfs/expanalog-2jwBANCu4_I-unsplash.jpg?width=900&height=608&name=expanalog-2jwBANCu4_I-unsplash.jpg)     ## What Is a Seawall? [A seawall is a durable structure that protects your property's waterfront](https://blog.duncanseawall.com/what-is-a-seawall-and-how-does-it-work) by deflecting waves as they hit the shore.

Seawalls work by stopping waves at the shoreline and reducing the force that reaches your land. Their structure absorbs and redirects wave energy, which helps prevent erosion right where it usually hits hardest.   [They can be built with different materials and structural designs ](https://www.duncanseawall.com/seawalls)that match the unique geography and marine conditions of each property. This customization ensures long lasting protection that fits the specific needs of your shoreline.   ![Seawall Duncan Sarasota-min](https://blog.duncanseawall.com/hs-fs/hubfs/Seawall%20Gallery%20-%202019/Seawall%20Duncan%20Sarasota-min.jpg?width=1000&height=660&name=Seawall%20Duncan%20Sarasota-min.jpg) --- While breakwaters may seem like a solution, they often cause more erosion to waterfront properties than they prevent.
