What is a Jetty? A jetty is a structure that extends from the shore into the water, and is typically constructed to protect a channel or harbor entrance from silting and erosion. Jetties can be made from a variety of materials—including rock, concrete, steel or even a combination of materials. The design of a jetty will depend on the specific location, the forces of waves and currents, and the intended application of the jetty. The Different Types of Jetties There are several different types of jetty designs available—each with their own specific uses and benefits, including: Design Considerations for Jetties Each jetty design offers its own set of advantages and disadvantages.…

A large number of waterfront structures are supported on piles. The piles may be constructed of timber, concrete or steel sections. The adverse environment introduced by seawater, high humidity, high temperature and dry-wet cycles causes rapid deterioration of these structures. The most severe conditions are found in the splash zone area, which encompasses the portion of the pile between the lowand high-tide water levels. The high concentration of chlorides in seawater allows it to penetrate and reach the reinforcing steel, even in high-quality concrete. As a result, the passive layer that normally protects steel is destroyed, making the corrosion of reinforcing or prestressing steel inevitable. Because corroded steel occupies a…

The wharf is a critical component of the marine transportation system, serving all maritime travel, trade, and development activities. The wharf structure is exposed to considerable impacts from the corrosive environment, erosion caused by waves, and microorganisms when in operation. The primary priority is investigating and implementing solutions to protect and maintain the wharf structure. This content will present four anti-corrosion solutions for wharves that are highly regarded and provide the most efficient performance nowadays. Why is jetty pile protection required to prevent corrosion? Corrosion is a common problem that occurs in all seaside wharf projects. There will undoubtedly be severe consequences if proper and timely wharf coating measures are not…
