A Comprehensive Guide to Maintaining Your Interlock Paver Driveway

An interlock paver driveway is an excellent investment for any home, providing both aesthetic appeal and durability. However, like any outdoor feature, it requires proper maintenance to keep it looking its best and performing well over time. At HMC London, we want to help you get the most out of your interlock paver driveway. Here’s a comprehensive guide to maintaining your driveway to ensure it remains in top condition for years to come.

1. Regular Cleaning

Keeping your interlock paver driveway clean is crucial for maintaining its appearance and preventing the buildup of dirt and debris. Here’s how you can effectively clean your driveway:

  • Sweeping: Regularly sweep your driveway to remove loose dirt, leaves, and debris. This simple step can prevent stains and buildup that could become more difficult to remove later.

  • Washing: For a deeper clean, use a garden hose or a pressure washer set to a low setting to rinse off dirt and grime. Be cautious with the pressure washer, as high pressure can dislodge the sand between the pavers.

  • Stain Removal: For oil stains or other stubborn marks, use a paver cleaner specifically designed for interlock pavers. Apply the cleaner according to the manufacturer’s instructions, scrub with a stiff brush, and rinse thoroughly.

2. Weed and Moss Control

Weeds and moss can sometimes grow between the pavers, detracting from the look of your driveway and potentially causing damage over time. Here’s how to manage and prevent their growth:

  • Weed Removal: Remove any weeds manually or use a weed killer that is safe for use around pavers. Be sure to follow the product instructions carefully to avoid damaging the pavers.

  • Moss Prevention: To prevent moss growth, ensure your driveway receives adequate sunlight and has proper drainage. If moss does appear, use a moss killer or a mixture of water and vinegar to treat the affected areas.

3. Polymeric Sand Replacement

The polymeric sand between the pavers plays a vital role in keeping them stable and preventing shifting. Over time, this sand can erode or wash away, so it’s important to replenish it as needed:

  • Inspecting: Regularly check the joints between the pavers for any signs of sand loss. If the sand level appears low, it’s time to add more.

  • Resanding: Use polymeric sand, which hardens when wet, to fill the joints. Pour the sand over the pavers and use a broom to sweep it into the joints, blow off any fines remaining on the surface with a leaf blower. Once the joints are filled, mist the area with water to activate the sand’s binding properties.

4. Sealing Your Pavers

Sealing your interlock paver driveway can protect it from stains, weather damage, and wear. While not always necessary, it can greatly enhance the longevity and appearance of your driveway:

  • Choosing a Sealer: Select a high-quality sealer specifically designed for interlock pavers. There are various types available, including wet-look, natural-look, and color-enhancing sealers.

  • Application: Clean the driveway thoroughly before applying the sealer. Follow the manufacturer’s instructions for application, usually using a roller or sprayer. Be sure to apply the sealer evenly and allow it to dry completely before using the driveway.

5. Addressing Repairs

Despite your best efforts, occasional repairs may be necessary to keep your interlock paver driveway in optimal condition:

  • Replacing Pavers: If a paver becomes cracked or damaged, it can be individually replaced. Carefully remove the damaged paver, clean the area, and insert a new paver, making sure it is level with the surrounding ones.

  • Leveling: Over time, some pavers may settle unevenly. To fix this, remove the affected pavers, add or adjust the base material, and reinstall the pavers, ensuring they are level with the rest of the driveway.
