Typical concrete seawall panels are either 5” or 6” in thickness. In order to raise the height of a concrete seawall, panels over 9 feet will need to be 8” thick. As the size and thickness of typical concrete seawall panels increase, so does the weight, impacting both the cost and difficulty of installation.
Thereof What is the best material for a sea wall? Concrete is one of the most durable materials used in seawalls. A concrete seawall will last for decades and require little or no maintenance.

What is the difference between a sea wall and a retaining wall? The purpose of a sea wall is to protect areas of human habitation, conservation and leisure activities from the action of tides, waves, or tsunamis.” “Retaining walls are relatively rigid walls used for supporting the soil mass laterally so that the soil can be retained at different levels on the two sides.
What is the main drawback of seawalls?
Seawalls can cause increased erosion in adjacent areas of the beach that do not have seawalls. This so-called “flanking erosion” takes place at the ends of seawalls. Wave energy can be reflected from a seawall sideways along the shore, causing coastal bluffs without protection to erode faster.
How long does a seawall last? Steel seawalls will typically last an average of 35 years. However, if galvanized, they will usually last a few years longer. Outcropping and rip rap, since they consist of rock and stones, usually outlast their steel counterparts. Given the proper attention and maintenance, these seawalls should last a lifetime.
