How Seawalls Provide Flood Protection For Seafront Homes


Seawalls protect the soil 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. Just on a much, much smaller scale! A seawall is normally made of wood, stone, concrete or steel.

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

Secondly, a seawall helps maintain water depth. This is especially important when you like boating, fishing, or other similar activities on your piece 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. Don’t let this intimidate you! Seawalls typically require very little upkeep. Periodic visual inspection and minor fixes should make up the majority of your”chores.”

You may want to build a seawall on your property. If so, check your 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 can help you avoid wasting money on a project you can’t finish. It can also give you guidelines on the very best strategies to construct your seawall.

Repairs and Maintenance

Inspect your seawall regularly so as to identify any problems before major issues arise.

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

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

Most lake communities have resources available to help homeowners keep their piece of the shoreline.

Don’t be afraid to ask for help!

Seawall Materials

Seawalls can be built from very different substances.

  • Concrete: This is typical for many different seawalls. Simply patch any little holes or cracks in the concrete so that they don’t disperse. If you find too much damage to repair on your own, call a professional. The material provides a amazing strength and will last around 25 years. It should be treated properly to make sure that it lasts through being subjected to water.

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

  • Riprap: Many homeowners prefer riprap because of its more natural look. Riprap is a barrier of very large stones along the waterline. The stone can be granite, limestone, concrete or other materials. Repair is very basic, and typically includes replacing any broken or scattered riprap.

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

Stopping Erosion

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

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

Planting extra grass or vegetation may give your soil additional protection. Incidental erosion just beyond the seawall can happen, as well, so keep an eye out for water pooling behind it.

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

After any major storm or flood, give your seawall a visual inspection to be certain it did not sustain any damage.

With just a little attention, this unassuming structure can protect you and your lake house for a long time to come.
