Sea Walls & Piers
A seawall is a coastal barrier constructed where the water, and related processes such as waves, directly impact the landforms of the coast.
The shoreline is a dynamic environment that changes over time due to the effects of erosion. A seawall's purpose is to protect developed land on the coast of a large body of water from the effects of erosion caused by wind and waves.
Due to the constant exposure to the forces of nature, seawalls do require periodic maintenance to retain their effectiveness, as well as needing to be eventually replaced.
