Breakwater Installation


Situated on the Gulf of Mexico, Bay St. Louis is home to more than 10,000 people. The city offers pristine beaches, a pedestrian bridge with an art walk, restaurants, shops and beautiful water views. Like several other Gulf Coast cities, Bay St. Louis, MS experienced extensive damage after Hurricane Katrina. Once recovery efforts were underway, the city put together a local business group, the Bay Area Recovery Team, to find opportunities that would enhance the visitor and citizen experience. After assessing various options, the team decided that a new downtown harbor would be the biggest asset to the city. The new harbor creates a waterfront gateway for the Bay St. Louis downtown and the harbor is connected to a recreational fishing pier. The downtown boulevard provides access for both tourists and residents to the new development.
Breakwater Design

Project Scope

After Hurricane Katrina devastated its waterfront and downtown area, the city of Bay St. Louis, MS. embarked upon a multi-year municipal harbor and pier project designed to spur economic development and increase tourism. The project includes four piers with room for a fifth, approximately 168 boat slips, a fuel dock, convenience pavilion, parking, restrooms and a harbor master facility. Thousands of feet of ShoreGuard® vinyl sheet piling was used for the project.
Marine Wall Installation


Unlike traditional construction materials such as wood or steel, ShoreGuard is corrosion-resistant, UV-resistant and impervious to marine worm damage. Vinyl sheet piling is also lightweight and easy to install, saving time and money on-site.
Heavy Duty Bulkhead


The design included approximately 1,100 linear feet of CMI’s 22-foot ShoreGuard 950 vinyl sheet pile, which was used as a breakwater on the North side (lee side) of the new harbor. Though a thinner ShoreGuard profile was originally specified, the SG 950 was ultimately selected for its high design strength, durability, performance and sustainability. In addition to providing extra structural support, ShoreGuard incorporates the company’s patented I-Beam Lock Technology, which enhances the lock integrity and seam reliability of the sheets.
