Seawalls, which are used to protect bays and canals from the damaging effects of waves, are a form of coastal defense. These huge structures protect coastal land from crashing waves. They are usually parallel to the shore and act as buffers against erosion.

Seawalls are designed to reflect waves back into the ocean instead of letting them impact the land, causing damage and erosion. Professional seawall installation services are recommended for waterfront properties.

Seawalls can be made of any material provided that they can withstand saltwater as well as impact forces. Vinyl, concrete, and even wood are all possible options.

The area, frequency, and power of waves will determine the material. The seawalls used for lakes will be different from the ones for rivers. They will also differ from the best for oceans.

Let's take a look at the most popular materials:

Vinyl Sheet Piling is the Most Popular Option

Many people choose vinyl sheet piling as their preferred seawall material. It is more attractive than concrete, and easier to maintain than wooden.

Vinyl is more popular in residential areas (and also for municipal waterfronts) because it looks great and is less expensive. Vinyl is resistant to rust, rot, and cracking when exposed to saltwater. Vinyl seawalls are easy to transport and set up because they are lightweight.


Concrete isn't as well-known as vinyl but is still used in many industrial applications for its strength. Concrete seawalls are made from rebar (reinforced steel) and can last for over 30 years if maintained properly.
