Once you’ve selected the perfect natural stone pavers for your hardscape, the next step is choosing the best method to fill the joints between them. Joint fillers not only impact the aesthetics but also affect the stability and maintenance of the pavers. Here are some of the most popular options for filling joints in your natural stone pavers:

Polymeric Sand for Paver Joints

Polymeric sand is a popular choice for filling joints between pavers because of its durability and functionality.

Considerations: One downside is that polymeric sand can leave a fine residue on the surface of the pavers if not carefully cleaned off during installation. In addition, it may need to be reapplied after several years, particularly in high-traffic areas.

How It Works: Polymeric sand is a mixture of fine sand and special binding agents. When activated with water, it hardens and bonds the pavers together, providing a solid joint that resists shifting, erosion, and weed growth.

Benefits: Polymeric sand creates a long-lasting, low-maintenance solution for keeping your pavers securely in place. It also helps reduce the growth of weeds between the joints.

Crushed Gravel for Paver Joints

Crushed gravel is an effective, natural option for filling the joints between pavers, especially if you’re aiming for a rustic or informal look.

Considerations: Gravel can shift over time, especially in areas with heavy rainfall or high foot traffic. It may need to be replenished periodically.

How It Works: Crushed gravel, such as pea gravel, is placed into the joints and compacted to form a stable base. This method allows water to drain freely between the pavers while preventing weed growth.

Benefits: Gravel is cost-effective, easy to install, and adds a natural, organic aesthetic to your hardscape. It’s also great for creating a permeable surface that allows rainwater to pass through.

Mortar or Concrete Joint Filling

For areas with heavy traffic or specific structural needs, mortar or concrete can provide a permanent solution for filling the joints between pavers.

Considerations: Over time, mortar or concrete may crack if the pavers shift or settle. This method is more permanent, making repairs or replacements more difficult if necessary.ndscape, including plant life and other materials. This ensures a balanced and cohesive design.

How It Works: Mortar or concrete is applied between the pavers, providing a strong, solid bond. This method is ideal for driveways or areas that need to support heavy loads.

Benefits: Mortar and concrete create durable, long-lasting joints that help prevent shifting and weed growth. They also offer a solid surface for high-traffic areas.

Groundcover Plants for Paver Joints

For an eco-friendly, visually appealing option, you can fill the joints between pavers with groundcover plants, moss, or low-growing vegetation.

Considerations: Groundcover plants require more maintenance, such as watering, trimming, and occasional replanting. Depending on your climate, some plants may not thrive and could need additional care.

How It Works: Small plants are placed in the gaps between the pavers. As the plants grow, they fill the joints and provide a lush, green look that softens the hardscape.

Benefits: Groundcover plants add beauty and texture to your hardscape, improving its overall appearance. They also contribute to water absorption and help maintain a sustainable, eco-friendly design.

Gravel or Sand Sweeping for Paver Joints

For a simple, budget-friendly solution, gravel or sand can be swept into the joints between pavers.

• How It Works: Fine gravel or sand is poured into the joints and swept into place, filling the gaps between the stones. This method is easy to install and works well for smaller-scale hardscapes.
• Benefits: This option is low-cost and easy to maintain. Gravel or sand also provides good drainage and flexibility, allowing for simple replacement when needed.
• Considerations: Over time, the gravel or sand can shift, particularly in areas with heavy rainfall or foot traffic. Periodic replenishing may be necessary.

Conclusion

The best method for filling the joints between your natural stone pavers depends on your design vision, traffic load, and maintenance preferences. Whether you choose polymeric sand for its durability, crushed gravel for its rustic charm, or groundcover plants for their natural beauty, selecting the right joint filler ensures your hardscape will remain stable, attractive, and functional for years to come.
