The purpose of seawalls and jetties is to create a strong barrier between land and the sea, but why do they fail over time?
The coastal walls reduce the energy of ocean waves and their impact on the surrounding land and its inhabitants in order to prevent coastal erosion. Seawalls redirect waves back into the sea, preventing damage and erosion over time. Constructing a sea wall can lead to many environmental concerns. For example, the loss of concrete and exposure to corroded steel severely weakens the seawall's lid and structure.
The following are some common symptoms of seawall failure:
1. Poor maintenance
2. Lack of inspection
3. Water entry
4. Cracks
5. Rust and corrosion
6. Footing shift due to erosion
7. Natural disasters
A jetty is another type of structure that extends from land to water. Depending on where they are used, jetties serve different purposes. Jetties are most commonly found along docks, rivers, beaches, or even behind waterfront properties. Rocks, steel, concrete, and timber are among the materials they are made of. It is not ideal to build jetties from timber in marine environments because timber is a high-maintenance material that needs frequent maintenance.
