How Seawalls Provide Flood Protection For Seafront Homes


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

In recent years, synthetic materials have become more popular. These structures serve three different purposes on the lake.

First of all, they protect property from erosion, flooding or poor drainage. Second, a seawall helps maintain water depth. This is especially important when you like boating, fishing, or other similar activities on your bit of the lake. Finally, seawalls can give your house an attractive, finished look. Particularly if your house is on a slope, it can make your property much more attractive.

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

You might want to construct a seawall on your property. If so, check the local regulations. Most lakes have requirements for any shore structure. For example, the Tennessee Valley Authority requires that you submit an application for any shore stabilization project.

Knowing regulations beforehand will help you avoid wasting money on a project you can’t finish. It can also provide you with guidelines on the most effective strategies to construct your seawall.

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

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

Maintenance and repair techniques will differ based upon the materials used.

Most lake communities have resources available to help homeowners maintain their bit of the shoreline.

Seawall Materials

Seawalls can be constructed from very different materials.

Simply patch any little holes or cracks in the concrete so that they don’t spread. If you find too much damage to repair by yourself, call a specialist.

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

  • Wood: You will 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, more economical product. It offers about 50 decades of life and comes in many different colours. On the downside, synthetic materials can be difficult to install. If you decide to install this type of seawall, hire a professional.

    Erosion happens to all land. Naturally, this is especially true for those properties located by the water.

    Rain, wind and the elements can eat away at any house over time. This can result in complications to any dwelling on the shore.

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

    For more natural seawall materials, such as riprap, promote natural vegetation. Plant growth will actually give your seawall equilibrium, and allow it to blend into the rest of your property.

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