With having access to the ocean or gulf, you have to prepare for potential hazards that can bring damage to your home or property, from floodwaters or other natural disasters. Building a well-structured seawall and maintaining it, can help protect your investment and keep your home safe from encroaching floodwaters. What is a seawall? A seawall is a wall or embankment that is expressly designed to prevent the sea from encroaching onto your land or eroding it over time. This is particularly important if you've built a house or other buildings on your land that could be damaged by the approach of ocean or gulf waters. Gardens, decorative areas, and playgrounds should also be protected by seawalls in order to secure your investment and protect yourself and your property. Visit Our Featured Seawalls Gallery VIEW OUR SEAWALL GALLERY The Advantages of Seawalls Building a seawall on your property is not without its advantages--and there are three key benefits you should consider when adding one to your property. Home value: Your seawall can increase the value of your home and property, helping it to sell faster and at a higher price when you're ready to move. Property protection: A well-built and well-maintained seawall will help protect your property in the event of a natural disaster. Personal protection: Floodwaters can rise fast and uncontrollably. By building a seawall on your property, you’ll gain valuable time when evacuating and could even prevent floodwaters from encroaching on your home. Types of Seawalls There are several different types of seawalls made with a range of materials. The type of seawall you choose will depend on the size of your property, your budget, and a range of other factors. Consider these types of seawalls and how their construction could potentially provide the protection you need for your home. Steel Seawalls Steel is both economical and sturdy, making it an excellent material for your seawall. Metal, in general, is designed to stand up well to a range of weather conditions, making it a wise choice in terms of both initial construction and longevity. Note, however, that steel is known to rust or corrode over time, especially when exposed to saltwater--something that you certainly have in large quantities just outside your seawall! Steel supports are often used as part of concrete seawall construction, which often makes it sturdier and more effective. It's also important to note that moving and installing steel may require heavy equipment that can be hard to move into certain areas, especially ecologically sensitive ones. For this reason, you should carefully evaluate your choice of materials before moving forward with steel. Vinyl Seawalls Vinyl seawalls are a more economical option that will allow you to more quickly and inexpensively install a seawall on your property. They provide an effective buffer against the waves that may encroach on your property, preventing you from losing soil and rocks across your property. These vinyl seawalls can also help provide a buffer against weather emergencies. Note, however, that vinyl seawalls are only intended to last for around 20 years, which can decrease your enjoyment of those seawalls and your property over time. Having them inspected and maintained regularly can help increase their longevity, while financially preparing for their replacement will ensure that you aren't surprised by the need to replace your seawall. Concrete Seawalls Concrete seawalls, which may include steel or other metal reinforcements, are one of the most durable seawall materials. Intended to last for fifty years or more under the conditions you're most likely to experience living near the water--including rain, waves, and salt water--concrete seawalls are made tough. The panels used to construct your concrete seawall can be custom designed to reflect the overall appearance of your property or to create the look you're after. Not only that, concrete seawalls require comparatively little maintenance. Once they're in place, you'll be able to thoroughly enjoy this long-term addition to your property. Composite Seawalls Composite seawalls aren't as tough as concrete or steel, but they will allow for a faster installation. They are made of pre-colored materials that are easy to install on your property, which means they'll be more likely to maintain their look long-term than other materials, which may need to be stained or painted in order to be maintained. Composite seawalls are also ideal for installation in areas that are difficult to get to or where ecological situations must be maintained. Wood Retaining Seawalls Wood retaining seawalls create a gorgeous natural look that will help prevent soil and land erosion around your property. These seawalls, however, may require more maintenance than other types of seawalls--especially on oceanfront properties, where increased erosion may be harder on your materials. How often you have to conduct maintenance on your wooden seawall will depend on your unique environment, the types of materials used, and the weather conditions during the lifetime of your wall. Seawall Construction Methods There are several methods commonly used to construct seawalls. The right one for your property will depend on the type of land you're covering, how much ground you need to cover, and a range of other factors. Curved seawalls are designed to follow the shape of the water, creating a simple curved effect around your property. They help disperse the energy of the waves more effectively than vertical seawalls, but must be specifically engineered to your property. Vertical seawalls are simply seawalls that go straight up. They're often built in a straight or semi-straight line. While they'll absorb the energy of the sea, they take more damage than curved seawalls, which help to redistribute the force of the ocean waves. Mounded seawalls are built of stacks of materials. Typically, these seawalls are temporary. They may be used during emergencies to help protect shorelines or to decrease the impact of waves. The type of seawall that works best for you may depend on where your property is located. For example, properties on freshwater lakes may be able to work more easily with vertical seawalls, while beachfront property owners may prefer the benefits of curved seawalls to help decrease the dangers to their property. Learn How the Condition Of Your Seawall Can Effect the Selling of Your Home DOWNLOAD THE FREE GUIDE The Evolution of the Seawall Seawalls have evolved substantially over the years. Consider some of these early seawall methods and how modern seawall construction has changed to shape more effective walls that are more likely to last. Seawalls have been around for a very long time. Early examples of seawalls were written about in Constantinople by 439--but there are traces of ancient seawalls that are even older. The first seawalls in the Boston area were made of cobb cribs. These early model seawalls required near-constant maintenance in order for them to continue to provide protection. In Pondicherry, India, an early seawall, constructed of granite boulders, was constructed around 1735. In 1784, the earliest stone seawalls were constructed in the Boston area. These walls were rough-hewn, with wooden bases that were sunk into the water. The 1800's saw a better understanding of how the base materials used behind seawalls could influence the maintenance and benefits of those seawalls over time. Modern soil mechanics became better understood in the 1920's, which led to more effective seawall construction across the United States and around the world. Today's seawalls are made from a wide range of materials utilizing a deep understanding of the way soil erosion and wave damage occurs over time. By better understanding these things, today's contractors are able to create more effective, longer-lasting seawalls. The Impact of Failed Seawalls Failing seawalls can lead to serious consequences for your home and property--especially in the event of a natural disaster or a weather emergency. Failed seawalls--which can be caused by long cracks, erosion holes, settling soil, or other property problems--can cause several issues, including: Difficulty selling your home, since failing seawalls can indicate other problems that can lead to financial difficulties later. Sinkholes Property damage caused by soil erosion or encroaching waves in the event of a natural disaster. Properly maintaining your seawall and ensuring that it will be able to easily protect your home will help prevent these problems--and regular inspections can help you get there. DIY Dangers There are plenty of articles out there on building a seawall yourself. Unfortunately, there are several problems associated with going the DIY route. First and foremost, building a seawall is a very technical process that should be completed by a professional team. While the DIY process may save you money up front, you'll quickly discover that working with a professional for more accurate seawall construction will lead to a more efficient seawall that will better protect your home and property as well as providing you with immense savings in repairs over time.
