All About Seawalls

What is a seawall, and what is its function? A seawall is a shoreline structure designed of concrete, masonry, or sheet piles. Seawall construction is typically built parallel to the shore. Investing in a professional seawall installation means that you will have a structure that protects the inland area against large waves and erosion. Smaller seawalls for private residential areas add aesthetic appeal to your waterfront property. 

Why Should I Invest in a Seawall?

You will need protection to prevent shoreline erosion from occurring for property alongside a river, lake, channel, or similar waterway. A seawall, while having an upfront cost, can be a worthwhile investment in the long run since it will help to prevent storm surges and erosion caused by wave energy. Seawalls can also help prevent flooding and property damage occurring from things like heavy storms or considerable boat traffic. Before making a decision, be sure to discuss the potential impact on the surrounding ecosystem with our seawall contractors and we'll help you determine the best solution.

Variation of Seawalls

Whether vertical, curved or stepped in structure, a seawall serves as a blocker to waves in the waterway that may otherwise cause flooding, erosion, or nuisance to a property's landscape.  Overall, there are four different styles of seawall structures:


  • Riprap seawalls consist of both large and small boulders, along with chunks of concrete. Riprap seawalls are a great choice for reinforcing the shoreline, preventing soil erosion that may result from light to moderate waves during a thunderstorm or boat traffic. Riprap seawalls are an excellent choice for shoreline protection.

  • Boulder seawalls bare resemblance to the decorative rock walls seen inland. These are aesthetically pleasing, constructed with large rocks and boulders, and are held together using mortar. This style is a great choice for waterfront properties that experience light to moderate waves.

  • Sheet pile seawalls deflect waves and prevent soil erosion. This seawall is anchored deep into the soil and laid against the bank for additional support. It's a good option for properties experiencing moderate wave action and are designed to minimize soil erosion.

  • Concrete seawalls are constructed in areas where there are frequent, large waves and storm surges that would otherwise impact the shoreline. They're built using large blocks of concrete that are poured into place. 

Seawall Materials

Seawall construction usually consists of the following materials:

  • Southern yellow pine

  • A galvanized steel tie beam system

The design of Southern yellow pine and the galvanized steel beam system is guaranteed to prevent soil from being pulled into the water and away from your waterfront property. Installing seawalls with riprap to create a natural habitat for fish and other shoreline animals is very common. At Radtke Contractors, we also welcome the incorporation of any shoreline plantings or structures into seawall design, such as docks, wall decks, and boat lifts.
