Introduction
Interlocking concrete pavers are also known as segmental pavers. For many decades, in the United States, the manufacturing and use of interlocking concrete pavers have been a decorative alternative to brick, clay, and concrete.
These versatile paving solutions are not only functional but also provide an aesthetic appeal that can enhance any outdoor space. Whether for a driveway, patio, or walkway, interlocking concrete pavers have become a favored choice among homeowners and landscapers alike.
The first interlocking concrete pavers were shaped as 4″x 8″ bricks, called Holland Stones; and they are still called that today. From those days, we have come to a wide variety of choices, too many to mention in this article.
With advancements in manufacturing technology, modern interlocking pavers come in various shapes, sizes, and colors, allowing for endless design possibilities. Homeowners can mix and match different styles to create unique patterns that reflect their personal taste.
The individual concrete pavers were not set in concrete but placed in sand, which performs better than concrete. The term interlocking comes from the fact that each concrete paver is locked to another paver and they cannot move independently from each other.
This interlocking mechanism not only provides stability but also allows for flexibility in the paving surface, which is particularly beneficial in regions prone to freeze-thaw cycles. This adaptability can reduce the likelihood of cracking and shifting, making interlocking pavers a durable option for various climates.
The interlock is the result of the sand placed in between each individual concrete paver. Not just any sand can be used for interlocking pavers. Sharp, angular joint sand must be used to maintain the interlocking properties.
Using the correct type of sand is crucial for the longevity of the installation as it helps to lock the pavers in place and prevents them from shifting under pressure. Homeowners should always consult with a professional to ensure the right materials are used for their specific project.
Concrete pavers are manufactured with a ridge which runs vertically on the side of each concrete paver to allow for proper spacing and to create a sand joint.
How to Clean Interlocking Concrete Pavers
If any petroleum products come in contact with concrete pavers, the pavers will need to be cleaned as soon as possible. The longer the petroleum product remains on the surface of the concrete paver, the deeper it penetrates into the surface, and the harder it will be to remove.
In addition to petroleum products, other common stains such as food spills, rust, or organic matter can also mar the appearance of concrete pavers. Regular maintenance is essential to keep them looking their best.
The best thing to use for cleaning petroleum products off the surface of concrete pavers is a high-quality, citrus-based liquid detergent.
Apply to the surface and let it soak for about 15 – 20 minutes; then wash the concrete paver with hot water. If the stained area isn’t completely clean; you may need to repeat this procedure more than once.
It is also advisable to use a pressure washer on a low setting for deeper cleaning, especially for stubborn stains. However, caution must be exercised to avoid damaging the pavers.
Another alternative is to replace the stained concrete pavers with new ones. This is not as easy as it sounds and honestly, if you act fast enough you can clean it away.
Sealing Concrete Pavers Protects Your Investment
This is no different than a concrete driveway or walkway as the concrete should be sealed to prolong its age. The base material is the same; the only difference is on the strength of the pavers vs. concrete and there is no rebar in the pavers.
After your interlocking pavers are installed, they are now exposed to all the outdoor elements (sun, rain, dirt, foot traffic, vehicle traffic, stains, etc.). Over time, the cement and color pigment of the pavers will gradually erode, causing the concrete pavers to change colors.
Moreover, the presence of moisture can lead to the growth of mold and mildew, which can further deteriorate the pavers’ appearance and structural integrity. Therefore, sealing becomes a vital step in the maintenance of concrete pavers.
A great way to protect your investment and help prevent the concrete pavers from eroding and changing colors is to seal them with a deep penetrating sealer.
Not only protection, it can help the sand in the joints to stay in place. That is not the main concern here though, and sand is cheap to add anyway.

Concrete Paver Sealer Product Types
There are two types of sealers for pavers. There are film-forming ones and non-film-forming ones. Don’t let it fool you though, there is more under the surface.
The choice between film-forming and non-film-forming sealers can significantly impact the performance and appearance of the pavers. Homeowners must consider the climate, the intended use of the pavers, and the desired finish when selecting a sealer.
Film-forming sealers offer that glossy surface while non-film-forming ones look like the matte finish. The glossy surface is good in the sense that it’s easier to see when the time to seal it again is coming. Matte surface lasts a little bit longer.
There is also solvent-based, water-based, acrylic, etc., kinds of sealers, so you might have to ask for a professional opinion on what to use. If you know your ground is wet, it’s good that the sealer can let some moisture through. Acrylics are really UV resistant on the other hand; so as you see, there are a lot of options when it comes to sealers.
Understanding the differences in these products will help you make an informed decision that best suits your needs. Many manufacturers offer guides and customer support to aid in the selection process, ensuring you choose the right product for your specific application.
Sealing and Protecting Interlocking Concrete Pavers
Quality commercial-grade sealers are designed to protect concrete pavers from the elements and guard them against erosion, oils, organic matter, and anything else that gets spilled and causes staining. The sealing of concrete pavers preserves the natural color and beauty for many years.
Now that you’ve made the investment in concrete pavers; it’s a good idea to protect your investment by sealing your pavers. After the concrete pavers have been sealed, you should re-seal every 3 to 5 years in order to keep your pavers looking new.
Sealing your concrete pavers will also play an important role in how long they last. Done regularly, it can double its lifetime which is a long time already. If you don’t like replacing your pavers every 10-20 years, seal them to last for a far longer time.
That’s possible because pavers have no rebar. That means it won’t rust and crack because of that. This inherent advantage of concrete pavers means that they can be a more cost-effective solution in the long run, despite a potentially higher initial investment compared to other materials.
Ordinary store brand sealers won’t last as long as sealers manufactured by a company that specializes only in paver sealers. Lower quality concrete paver sealers can turn white and cloudy, detracting from the overall appearance of your paved area.
This can lead to problems for future re-sealing; resulting in having to strip off the old sealer, which can be expensive and may cause damage to the concrete pavers. Therefore, investing in a high-quality sealer is crucial to maintaining the integrity and appearance of your pavers.
The process of sealing concrete pavers is not difficult; however, a company certified by the concrete paver sealer manufacturer is your best bet. They have been educated and certified in the products and the process, and have generally installed a variety of paver sealing jobs.
For those who prefer to tackle this project themselves, it’s important to follow the manufacturer’s instructions carefully. A pump sprayer, short hair paint roller, and sealer should do the trick. You can look at this acid staining guide and how the sealer is applied for reference.
Additional Tips for Maintaining Concrete Pavers
In addition to sealing, regular maintenance is essential to prolong the life of your concrete pavers. Here are some additional tips to keep your pavers looking their best:
- Regular Cleaning: Sweep away debris and dust regularly to prevent dirt buildup and staining. A gentle power wash can help remove more stubborn grime.
- Joint Sand Replacement: Over time, the sand in the joints may wash away. Replenishing this sand will help maintain the interlocking system and prevent weed growth.
- Weed Control: To prevent weeds from growing between the pavers, consider using a weed barrier fabric or applying a commercial weed killer in accordance with the product instructions.
- Addressing Stains Promptly: Always address spills and stains as soon as they occur. The longer a stain sits, the harder it can become to remove.
- Inspecting for Damage: Periodically inspect the pavers for any signs of damage or shifting. Early detection allows for timely repairs.
Understanding the Benefits of Interlocking Concrete Pavers
Interlocking concrete pavers provide a unique combination of strength, versatility, and style that makes them an ideal choice for various landscaping projects. They are not only visually appealing but also offer several practical advantages that can enhance the overall value of a property.

One of the most significant benefits of interlocking concrete pavers is their durability. When installed correctly, they can withstand heavy loads and resist cracking, which is essential for high-traffic areas such as driveways and walkways. Unlike traditional concrete slabs, they do not require control joints, which are often the weak points in a concrete surface. This means that interlocking pavers can maintain their integrity even under extreme weather conditions.
Moreover, because they are designed to move slightly with changing temperatures and conditions, they are less likely to suffer from damage due to freeze-thaw cycles, which can be a common issue in colder climates. This inherent flexibility allows homeowners to enjoy their pavers for years without the frequent need for repairs or replacements.
Aesthetic Appeal
The versatility of interlocking concrete pavers allows homeowners to create stunning outdoor spaces that reflect their style and preferences. With a wide variety of colors, shapes, and textures available, it’s easy to match pavers to the existing architecture and landscape design of a home.
Homeowners can experiment with different laying patterns, such as herringbone, basket weave, or running bond, to achieve a unique look. This creative freedom can significantly enhance the curb appeal of a property, making it stand out in the neighborhood.
Eco-Friendly Option
Another noteworthy advantage of interlocking concrete pavers is their eco-friendliness. Many manufacturers offer permeable pavers, which allow rainwater to pass through the surface and recharge groundwater supplies. This not only helps to reduce runoff and surface water pollution but also mitigates flooding and erosion, making them a responsible choice for environmentally-conscious homeowners.
Additionally, the materials used in paver production are often made from recycled content, further reducing their environmental impact. By choosing interlocking concrete pavers, homeowners can contribute to a sustainable future while enhancing their outdoor spaces.
Cost-Effectiveness
While the initial installation cost of interlocking concrete pavers may be higher than that of traditional concrete or asphalt, the long-term savings can be substantial. The durability and low maintenance requirements of pavers mean that homeowners will spend less time and money on repairs and replacements over the years. Furthermore, proper sealing and maintenance can extend the lifespan of pavers, enhancing their cost-effectiveness.
When considering the total cost of ownership, including maintenance, repairs, and aesthetic value, interlocking concrete pavers often prove to be a wise investment that can increase property value.
Choosing the Right Pavers for Your Project
Understanding the various types of interlocking concrete pavers available is essential for selecting the right ones for your landscaping project. Here are some key factors to consider:
Material Composition
Interlocking pavers can be made from different materials, including standard concrete, colored concrete, or even recycled materials. Each type has its unique benefits, so consider the desired look and performance characteristics when making your selection. For example, colored concrete pavers can add visual interest but may require additional sealing to maintain their hue over time.
Thickness and Size
The thickness and size of the pavers can affect their strength and suitability for various applications. Thicker pavers are typically recommended for high-traffic areas, while thinner pavers may be more appropriate for decorative pathways or patios. Assessing the intended use will help determine the best options for your project.
Color and Texture
Choosing the right color and texture can significantly impact the overall aesthetic of your outdoor space. Consider the existing colors of your home, landscape, and other hardscape elements. Textured pavers can provide slip resistance, making them a safe option for pool decks or wet areas.
Pattern and Design
Finally, the laying pattern and design of the pavers can transform the look of your outdoor area. Experimenting with various patterns can create visual interest and enhance the overall appeal. Consult with a landscaping professional for design ideas and to ensure that your chosen pattern is practical for installation.
Conclusion
Adding sealer to the concrete is like painting a wall. The heavy lift is having that wall built and prepared for the paint, and it’s like that with the pavers as well.
First, you excavate, add gravel for drainage, and sand for pavers install. Then you install the pavers and add sand to the joints. It only makes sense to take steps to protect that work and investment.
In summary, interlocking concrete pavers present an array of benefits, including durability, aesthetic appeal, and eco-friendliness. By understanding the advantages of these paving solutions and choosing the right products for your project, you can create stunning outdoor spaces that add value and beauty to your home.
With proper installation and maintenance, interlocking concrete pavers can serve as a long-lasting investment that enhances your property’s curb appeal and functionality. Whether you are considering a new driveway, patio, or walkway, interlocking concrete pavers are an excellent choice that can meet your needs for style and durability.
Ultimately, investing in high-quality materials and following best practices for maintenance will ensure that your interlocking concrete pavers remain an attractive and functional feature of your landscape for many years to come.
