How Seawalls Provide Flood Protection For Seafront Homes


Seawalls protect the land from erosion with a body of water. If you have seen a seawall on the beach, just know that seawalls on the lake serve the same purpose. A seawall is normally made from wood, stone, concrete or steel.

Recently, synthetic materials have become more popular. These structures serve three distinct purposes on the lake.

To begin with, they protect property from erosion, flooding or poor drainage. Second, a seawall helps preserve water depth. This is especially important if you enjoy boating, fishing, or other similar tasks on your bit of the lake. In the end, seawalls may give your property an attractive, finished look. Particularly if your property is on a slope, it can make your property far more attractive.

If you own a house on the waterfront, you may be liable for a seawall. Do not let this intimidate you! Seawalls typically require very little maintenance. Periodic visual inspection and minor fixes should compose the vast majority of your”chores.”

You may choose to build a seawall on your premises. If so, check the local regulations. Most lakes have requirements for any shore structure. By way of example, the Tennessee Valley Authority requires you to fill out an application for any shore stabilization project.

Knowing regulations beforehand will help you avoid wasting money on a job you can’t finish. It can also give you guidelines on the very best strategies to build your seawall.

Repairs and Maintenance

Inspect your seawall regularly in order to identify any problems before major issues arise.

If your seawall is new, be cautious and make note of any sinkholes or cracks. Other defects may occur due to age.

Care and repair techniques will fluctuate depending on the materials used.

If you don’t know the local guidelines on maintaining a seawall, ask your neighbors. Most lake communities have resources available to help homeowners maintain their bit of the shoreline.

Don’t hesitate to ask for support!

Seawall Materials

Seawalls can be built from very different substances.

  • Concrete: This is typical for many different seawalls. It will last around 30 years, if built correctly. Simply patch any little cracks or holes in the concrete so that they don’t disperse. If you find too much damage to repair by yourself, call a professional.

  • Steel: Steel sheet piling is typical for both seawalls and bulkheads. The material provides a amazing strength and will last around 25 years. It should be treated properly to ensure that it continues through being exposed to water.

  • Wood: You may see wooden seawalls in more rural and residential areas. Just like steel, it should be treated properly in order to last.

  • Riprap: Many homeowners prefer riprap for its more natural appearance. The stone can be granite, limestone, concrete or other materials. Repair is extremely basic, and typically includes replacing any broken or scattered riprap.

  • Vinyl or Plastic: This is a newer, cheaper product. It offers about 50 decades of life and comes in several different colors. On the downside, synthetic substances can be difficult to install. If you choose to install this sort of seawall, hire an expert.

Stopping Erosion

Erosion occurs to all land. Of course, this is especially true for those properties located by the water.

Rain, wind and the elements can eat away at any property over time. This may cause complications to any home on the shore.

Planting extra grass or vegetation may provide your soil additional protection. Incidental erosion just beyond the seawall can occur, too, so keep a look out for water pooling behind it.

For more natural seawall substances, such as riprap, promote natural vegetation. Plant growth will actually provide your seawall equilibrium, and help it blend in to the rest of your premises.

After any significant storm or flood, give your seawall a visual inspection to be certain it didn’t sustain any damage.

With only a little attention, this unassuming structure can protect you and your lake house for decades to come.
