6 Things You Need To Know Before Building A Rock Revetment

Rock Revetment

Rock revetments are a familiar site in coastal areas, whether they’re built to protect a coastline or to contain a lake. Many companies offer a wide range of services, including installation, design consultation, and ongoing maintenance. If you’re interested in building a rock revetment on your property, be sure to contact a reputable rock revetment construction contractor. Talking with contractors can help ensure that you get the best possible results.

Building a Rock Revetment

Building a rock revetment is a great way to protect your shoreline from erosion. But before you start, there are a few things you need to know.

First, you’ll need to choose the right rocks. The rocks should be large enough to resist the forces of waves and currents, but not so large that they’re difficult to work with. You’ll also want to make sure the rocks are smooth, so they won’t damage your property or injure people who come in contact with them.

Second, you’ll need to prepare the site where you’ll be building the revetment. This means clearing away any vegetation and leveling the ground. You may also need to excavate part of the shoreline so that the rocks will sit at the correct elevation.

Third, you’ll need to build a solid foundation for the revetment. This can be done with concrete blocks or timbers that are driven into the ground. The foundation should be level and firm so that it can support the weight of the rocks.

Fourth, you’ll need to place the rocks on top of the foundation. The best way to do this is to lay them in a staggered pattern so that they interlock with each other. This will help keep them in place during storms and high water levels.

Finally, you’ll need to backfill around the rocks and secure them with wire mesh or rebar. This will help prevent erosion and keep your revetment looking its best.


Before you begin building a rock revetment, you will need to gather the following materials:

-Large rocks or boulders (at least 2 feet in diameter)

-Smaller rocks or pebbles (for filling in gaps between larger rocks)



-Tamping tool (such as a tamper or hand tamp)

-Pounding tool (such as a sledgehammer or heavy hammer)

-String line and stakes


-Landscape fabric

-Construction adhesive

-Rock saw (optional)

Dealing with Water

Water is one of the most powerful forces on Earth, and it can quickly erode even the strongest rock walls. To build a rock revetment that will withstand the force of water, you need to take some special precautions. Here are a few things you need to know before building a rock revetment:

1. The first step is to find a stable location. The rocks you use for your revetment must be placed on firm ground that won’t shift or erode over time.

2. Once you’ve found a stable location, dig a trench around the perimeter of the area where you’ll be placing your rocks. The trench should be at least 2 feet deep and 2 feet wide.

3. Line the trench with a layer of heavy-duty fabric or tar paper to help prevent erosion.

4. Begin placing your rocks in the trench, starting with the largest ones first. As you place each rock, make sure it is securely seated in the trench and that there is no gaps between the rocks.

5. When all the rocks are in place, cover them with another layer of fabric or tar paper and then backfill the trench with dirt or gravel. This will help keep your revetment in place during periods of high water flow.


Assuming you are looking to build a rock revetment to prevent erosion:

You will need to have a land survey done in order to determine your property boundaries. This is important because you will need to get any necessary permits from your local municipality before starting construction.

Next, you will need to excavate the area where the revetment will be built. The depth of the excavation will depend on the height of the revetment. Once the excavation is complete, you will need to install a layer of filter fabric at the bottom of the trench.

After the filter fabric is in place, you will begin installing the rocks that make up the revetment. The rocks should be placed in a staggered pattern and should be tightly packed together. As you are placing the rocks, be sure to check that they are level so that your revetment is even.

Once all the rocks are in place, you will need to backfill the trench with soil and compact it down. Then, you can add any vegetation or landscaping that you desire.

Landscape Design

The landscape design of your rock revetment will play a large role in how effective and pleasing it is. When choosing a design, consider the following factors:

  • Your site’s natural features
  • The type of rock you’re using
  • Your aesthetic goals

When designing your revetment, keep in mind the following considerations:

  • Height and width: Your revetment should be as tall as possible while still being aesthetically pleasing, and it should be as wide as necessary to cover the entire area.
  • Design features: You may want to include features such as steps or protrusions to make the revetment more interesting and visually appealing.
  • Landscape elements: Add trees, plants, boulders, or whatever else makes your site unique and adds character. Remember to coordinate these elements with the rest of your landscaping to create a cohesive whole.

Other Considerations

There are a few other things to consider before you start building your rock revetment.

First, you’ll need to determine the slope of the land. This will help you determine how much rock you’ll need to build up the revetment.

Second, you’ll need to choose the type of rock you want to use. There are many different types of rocks available, so be sure to do your research and choose the one that’s right for your project.

Third, you’ll need to figure out how you’re going to secure the rocks in place. There are several different methods available, so again, be sure to do your research and choose the one that’s right for your project.
