Some Basic Information About Seawalls
If you are a newcomer to Florida, or just new to living on the waterfront, you may want to learn some basic information about waterfront properties and the marine structures that protect them. So, let’s start by answering some general questions about seawalls.
What is a Seawall?
A seawall is a marine structure, also often referred to as an embankment, that defends a waterfront property’s shoreline from erosion and potential flooding. It’s also a type of coastal defense solution that helps protect the land (your property) from the impact of the “sea” or wave action from the water.
What Does a Seawall Look Like?
Seawalls come in a variety of shapes and sizes. And they can be constructed from various materials such as performance vinyl and composite sheet piling, stone (rip rap), concrete, or specialty treated wood. Most seawalls have a vertical or sloping structure and can be smooth, step-faced or curved-faced. But they are all marine structures built to protect the shoreline from the water.
The stability of a seawall is dependent on a variety of variables such as wall height, sheet pile length and strength, wale system, backfill, foundation soil and tide. And since each seawall project has its own unique set of requirements, Gibson Marine Construction builds each seawall using top-quality products and creates a design plan to meet each job’s unique challenges.
What is the Purpose of a Seawall?
A seawall helps to protect a waterfront property from various types of damage that the water can cause to the land. Various jobs seawalls perform include:
- Helping to defend against erosion
- Serving as a barrier to protect against potential flooding and minimize the potential damage caused by large heavy waves from storms and hurricanes
- Protecting waterfront structures from wave action and corrosion.
What is the Main Drawback of a Seawall?
Seawalls require regular inspections and maintenance. If left unchecked for an extended period of time, seawalls could require extensive repairs and/or eventually fail leading to extensive and expensive property damage.
Do I Need a Seawall?
Most structures built close to a body of water could benefit from a seawall. If water is encroaching on your land or structures or it is causing damage to your property, a seawall could help minimize or even prevent further damage by creating a protective barrier between your property and the water.
How Much Does a Seawall Cost?
A seawall in Florida will cost on average around $150 per linear foot, depending on what materials are used. For a more specific estimate on your Florida seawall project, contact Gibson Marine Construction for a free quote.
