Sea walls are a must in order to protect a waterfront property. Most sea walls in Florida were constructed over 50 years ago and all are getting close to its 30 year life expectancy.
Most seawalls are in need of repair and with a fairly simple inspection one can look for those signs. Many times there are small sinkholes which indicate there is wall deterioration. Cracks with rust colored water marks on the cap or below on the wall are also signs that salt water is corroding rebar. When the
rebar rusts it expands and generates additional cracks. When a major event such as high seas or a storm further stresses the wall then you can face a catastrophic collapse. Marine - A1346
Types of Sea walls
There are several types of sea walls. Steel walls are economical and strong , however metal will rust with the environmental harsh conditions in a waterfront property. Steel wall parts are heavy and difficult to move into crowded places. Steel is generally used with concrete to which makes the wall much stronger
but might not be usable if there are environmentally issues to take into account.
Vinyl Sea walls are economical, but they will not last much more than 20 years. For a long term investment there could be other alternatives that can last much more. Composite walls are not as strong as steel ,but installation is much easier. They can be made in different colors and will maintain their color over time. They are easy to handle and can be carried easily by hand into a crowded space.
