What is Pea Gravel?
Pea gravel is a type of gravel that is made up of small, rounded stones. The size of pea gravel is usually between 1/8 to 3/8 inches, which is much smaller than other types of gravel. Pea gravel is often used as a decorative element in landscaping, as well as in the construction of pathways, patios, and other outdoor surfaces.
One of the unique features of pea gravel is its shape. Unlike other types of gravel, which are made up of jagged or angular stones, pea gravel is made up of rounded stones that have been smoothed by water over time. This gives pea gravel a softer, more natural appearance that is especially appealing in outdoor settings.
Pea gravel is also prized for its versatility and durability. It can be used in a variety of applications, such as in drainage systems, as a decorative mulch in garden beds, or as a top layer on outdoor surfaces. Pea gravel is also relatively low maintenance, which makes it a popular choice for homeowners who want an attractive outdoor space without having to spend a lot of time on upkeep.
In order to keep pea gravel in place and prevent it from shifting or becoming displaced over time, glue can be used to bind the stones together. There are several types of glue that are commonly used for this purpose, including epoxy resin, polyurethane, and polyurethane epoxy.
Using glue to hold pea gravel in place can offer several benefits, including enhanced durability, avoiding displacement, and reduced maintenance. For more information on the types of glue that can be used with pea gravel, see the next section of this article.
Why Use Glue?
Enhanced Durability, Avoiding Displacement, and Reduced Maintenance are several reasons why you should consider using glue when working with pea gravel. The use of glue to stabilize gravel has been increasing in popularity over the past several years, and for good reason. It not only helps to improve the appearance of landscaping projects but also offers numerous benefits. By using the right glue and following the proper steps, you can create a durable and sustainable surface that will require far less maintenance over time.
Enhanced Durability
Using glue to bind pea gravel together can significantly boost its durability. Stones can easily move and become displaced due to different weather factors or weight and use over time, which can be particularly frustrating for homeowners. However, when it is bonded with a strong adhesive, pea gravel can last longer and withstand more exposure.
Increased Lifespan: One of the most significant benefits of gluing pea gravel together is that it has an increased lifespan. The glue helps to bind the pieces of gravel together, creating a solid and robust surface. Consequently, it will prevent the stones from moving or getting displaced, which means that the surface will look as good as new for much longer. Ultimately, it can help homeowners save the time, effort, and money needed to restore their pea gravel surfaces continually.
Reduced Maintenance: Pea gravel surfaces require regular maintenance, which can be costly and time-consuming. However, gluing pea gravel together can help minimize the required maintenance, as the adhesive adds an extra layer of protection to the surface. By preventing the stones from moving, there will be fewer gaps in the surface for unwanted weeds to grow. Removing debris and dirt will be easier, as there will be no need to fill in gaps or remove small rocks.
Increased Performance: Using glue to hold together pea gravel enhances its performance. The bond created by the adhesive results in a more durable and stable surface, which makes it more comfortable and safer to walk or drive on. It can be particularly useful if being used in areas such as driveways where there is frequent and heavy traffic.
Better Aesthetics: Gluing pea gravel together can improve the exterior of a property, as it will look neater and more groomed. Having a neat and clean driveway, patio, or path can increase your home’s curb appeal, making it more attractive to potential buyers if you ever want to sell your property.
This enhanced durability provided by using glue will allow you to use your pea gravel surface for an extended time without needing repair. This added stability may also ensures that the surface is safer for activities such as walking or driving.
Avoiding Displacement
When pea gravel is used for landscaping, one issue that may arise is its displacement due to heavy rains, wind, and foot traffic. Using glue to bind pea gravel together can prevent it from spreading and moving around. This can be especially useful for areas that are most prone to displacement, such as garden paths and driveways.
By bonding pea gravel with glue, you can prevent:
| Issue | Consequence |
|---|---|
| Gravel displacement due to foot traffic | Uneven or sparse gravel patches that can cause accidents and require frequent maintenance |
| Gravel displacement due to heavy rainfall or winds | Gravel entering and clogging drainage systems, dirtying nearby surfaces, or spreading to unintended areas |
By preventing gravel displacement, you can achieve a more stable, uniform, and clean-looking surface. You’ll also save time and resources since you’ll need to replenish the gravel less frequently.
It’s worth noting that some types of glue can be more effective than others in preventing gravel displacement. For example, polyurethane glue is known for its high resistance to water and temperature changes, making it ideal for outdoor use. Epoxy resin, on the other hand, may shrink or yellow over time when exposed to UV rays, so it may be better suited for indoor or low-traffic applications.
However, in most cases, combining different types of glue can result in a more durable and customized bond, depending on your specific needs and preferences. Airplane glue, for instance, is a type of cyanoacrylate glue that can provide a strong and instant bond, but may not be as resistant to moisture or vibration as other types of glue.
By carefully considering your options and choosing the right glue, you can ensure that your pea gravel surface won’t budge, no matter what.
Reduced Maintenance
Using glue to secure pea gravel has several benefits, including reduced maintenance. Once the gravel is glued together, it is less likely to shift or displace, which means you won’t have to worry about constantly raking or adding more gravel. This also means that there will be less debris to clean up, saving you time and effort.
Additionally, using glue can help prevent weeds and other vegetation from growing in between the gravel. This is especially important for paths or walkways, where weeds can be unsightly and can even cause damage to the surface.
Take note that while using glue can reduce maintenance, it is still important to periodically check and minor repairs if necessary.

Step 3: Apply the Glue
To apply the glue, follow these simple steps:
- Clean the surface: Make sure the area where you’ll be applying the glue is clean and free from any debris or loose gravel. Use a broom or a blower to remove any dust or dirt.
- Mix the glue: Depending on the type of glue you’re using, you may need to mix it with a hardener or catalyst in a separate container. Follow the manufacturer’s instructions carefully to ensure proper mixing.
- Apply the glue: Using a trowel or a gloved hand, apply the glue in a thin, even layer on the surface. Be careful not to apply too much as it can create bumps and unevenness. Work in small sections to make sure the glue doesn’t dry out before you’re able to apply the pea gravel.
- Add the pea gravel: Once the glue is applied, carefully pour the pea gravel on top. Use a rake or a broom to spread the gravel evenly and press it down lightly to ensure it adheres to the glue.
- Repeat: Continue applying the glue and pea gravel in small sections until you’ve covered the entire area. Allow the glue to dry completely before walking or placing any heavy objects on the surface.
It’s important to note that the drying time will vary depending on the type of glue you’re using and the temperature and humidity of your environment. Be sure to follow the manufacturer’s recommended drying time before using the surface.
Step 4: Spread the Pea Gravel
Now that the glue has been applied, it’s time to spread the pea gravel onto the surface. This is a crucial step in the process, so make sure to take your time and do it properly. Here are the steps to follow:
- Start from the furthest point: Begin spreading the pea gravel from the furthest point away from where you plan on exiting. This will ensure that you don’t accidentally step on the glued area and ruin your hard work.
- Use your hands or a shovel/cultivator: Depending on the size of the area, you can use your hands to spread the pea gravel or a tool like a shovel or cultivator to help cover the surface evenly and efficiently.
- Apply pressure: Once the pea gravel is spread out, use a tamper or a piece of lumber to apply pressure to the surface. This will help the gravel settle into the glue and create a strong bond.
- Check for evenness: Walk around the area and check if the pea gravel is evenly distributed. If there are any spots that need more gravel, add it in and apply pressure once again.
- Let it dry: Let the pea gravel and the glue dry completely before stepping on it or allowing any heavy traffic. This will ensure that the glue has fully set and the bond is strong.
Remember, taking your time during this step will ensure a beautiful finished product that will last for years to come.
Step 5: Apply a Binding Solution (Optional)
For added strength and durability, applying a binding solution to your glued pea gravel can be a good idea. This optional step can help ensure that your pea gravel remains in place and doesn’t shift or displace easily.
One popular binding solution for pea gravel is polyurethane sealant. This sealant is typically a clear liquid that is applied directly to the surface of the pea gravel. Once applied, the sealant will dry and create a protective layer over the pea gravel that will help bind the individual stones together and add an extra layer of stability.
Another option for a binding solution is using a mixture of water and white glue. This is a more affordable option that can also be just as effective at holding pea gravel in place. To create this binding solution, mix equal parts water and white glue in a bucket. Mix the solution until it is well blended, then apply it to the pea gravel surface using a brush or roller.
It is worth noting that using a binding solution is an optional step and may not be necessary for all projects. If your pea gravel is only used for aesthetic purposes in a low-traffic area, you may not need to take this extra step. But if you’re using your pea gravel for pathways or driveways, applying a binding solution can help ensure that it remains in place and provides a safe and stable surface.
Below is a table summarizing the steps for applying a binding solution to your glued pea gravel:
| Step 1 | Choose the binding solution you will use. Polyurethane sealant or water and white glue can both work well. |
