30-50 years
A seawall that is properly maintained can last from 30-50 years, if not properly maintained you can expect to have to repair it in as little as 20 years.
What is the best type of seawall?
Concrete is one of the most durable materials used in seawalls. A concrete seawall will last for decades and require little or no maintenance. Concrete panels are preferable in large seawalls, since reinforced concrete is stronger than most other materials and can be custom designed for aesthetically appealing results.
Can you build a seawall yourself?

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?
The high cost of construction and maintenance. Its elevated cost leaves some people wondering whether its expensiveness is worth it. But despite having high construction and maintenance costs they offer a long-term solution. Some designs of these seawalls might be unattractive.
How tall should a seawall be?
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.
What is the difference between a levee and a seawall?
However, a seawall is specific to larger bodies of water, like an ocean, sea or gulf. Unlike a levee, a seawall constructed out of precast concrete will not erode, allowing the beach itself to withstand erosion as well (a major problem in most coastal areas).
What are alternatives to sea walls?
Green infrastructure provides a viable alternative to seawalls for storm surge risk. Parks, green spaces, and plant-covered hills are an effective defence against storm surges and tsunamis, according to a Stanford University study.
