Due to its affordability, environmental friendliness, and corrosion resistance, vinyl sheet pilings are a preferred material for seawall construction. A Vinyl piling is more corrosion resistant than most conventional materials. Having a strong and stable seawall, protects and adds value to your home.


Now for the question, how is a seawall built? When building vinyl seawalls, you can feel secure in the decision that your installation will be easier and faster than other material choices. it installs fairly quick and easy. Building a seawall typically takes around two weeks.

Other pros to using vinyl are that it is environmentally friendly, and prevents dangerous substances from seeping into the water to be fed to organisms and the wall-mounted feeders.

Vinyl is a durable substance, so elements like the sun won’t harm it over time. Polyvinyl chloride is the chemical that creates vinyl sheet piling. The interlocking design, (PVC) is frequently used to reinforce and protect fresh concrete from the constantly moving water.

Required Components for Building A Seawall


The sheeting establishes the material strength, depth, and thickness, and is the most crucial component of the construction.

Deciding on a cap design depends on careful consideration and comparison. These aspects depend on the level of durability, appeal, and price you desire. Other options include those made of concrete, wood, steel, and aluminum.

Deadman and Manta Ray Systems

The deadman system is utilized when there is sufficient space. A swimming pool in the path, for instance, would require using a different strategy.  A deadman anchor is a poured concrete block that anchors structural support with tie rods around 15ft back from the seawall. If a pool is in close proximity, the manta ray, a toggle bolt that resembles a manta ray fish, is another earth anchoring method.

Wale Systems

Wale systems come in a variety of materials and price points. The system runs along the face of the wall and acts as a key support system beam. It increases stability from the earth giving way underneath and disperses the pressure from the deadman rods. How many anchors used and how frequently may depend on how strong the materials are. For taller walls, wales are utilized and positioned according to the soil pressure behind the wall.

Drainage Installation

Drainage is essential when installing a seawalls and pilings. The stability of the soil serves as the property foundation and a drainage system. You can prevent seawall damage by adding a drain which will balance the pressure on the land and water sides of the seawall.

Cost Factors

A seawall can cost between 10,000 and 100,000 dollars. The cost depends on a number of factors, including the material, location, government licensing and restrictions, and the integrity of the existing foundation. The upfront expense of permits and licenses does not sound unreasonable if you build a long-lasting seawall.

Materials like concrete and steel cost more than rocks and vinyl. Permit prices vary depending on the state you’re in. For these kinds of licenses, Florida has some of the highest price points. Poured concrete and vinyl both have a 50–60 year lifespan. Steel and aluminum have a 30- to 40-year lifespan. Wood has a 25-year lifespan.

Materials corrode quicker in saltwater than in freshwater. Materials for saltwater will therefore be more expensive. Whereas the water’s composition varies, it’s also important to take into account how the tides will change and what the sea level will ordinarily be.
