A cobblestone driveway combines durability with a classic look. Laying it requires good preparation and precision. Here are the main steps:
- Preparation: Measure the location accurately, ensure a solid base, and maintain a 2% slope for water drainage.
- Foundation: Excavate the ground to a depth of 30 cm and lay layers of gravel (15 cm) and bedding sand (5 cm). Compact each layer thoroughly.
- Laying Cobblestones: Choose a pattern like herringbone (ideal for driveways) and place the stones with a joint of 3-5 mm.
- Finishing: Fill the joints with jointing sand or polymeric sand and compact the surface firmly.
Requirements:
Tools such as a compactor, rubber mallet, and measuring tape, and materials like cobblestones, stabilization sand, and geotextile. Always check for cables or pipes in the ground before starting.
With good preparation and regular maintenance, such as sweeping and refilling joints, your cobblestone driveway can last for decades.
Getting Started
Measuring the Location
Start by marking the corner points of your driveway with stakes and then measure:
- The total length and width of the driveway
- The diagonals to check if the angles are right
- The height difference between the start and endpoint
For good water drainage, a slope of 2% is ideal. For a driveway of 10 meters, this means a height difference of about 20 cm. Use a laser or spirit level to mark this accurately.
Then calculate exactly how many materials you need or seek advice at Bricknest.
Once all measurements are correct, you can gather the necessary tools and materials.

Ground Preparation
Excavating the Base
A solid foundation is essential for a durable cobblestone driveway. Excavate the subsoil to a depth of 30 cm. This prevents frost damage, which is crucial in the Dutch climate.
Maintain a slope of 2% (for example, 10 cm height difference over 5 meters) to drain the water properly. Use a level or laser to set the slope accurately.
What to watch for when excavating?
- Check with KLIC if there are cables and pipes in the ground.
- Remove roots, plants, and other organic materials.
- Ensure sturdy edges around the excavated area.
- Use geotextile if working on clay or peat soil to prevent subsidence.
After excavation, you can start building the foundation.
Building the Foundation
The foundation consists of different layers, each with a specific function. Bricknest advises the following structure:
| Layer | Material | Thickness | Function |
|---|---|---|---|
| Sub-layer | Gravel | 15 cm | Stability |
| Bedding layer | Sharp sand | 5 cm | Levelling |
Thoroughly compact each layer in two directions with a compactor. Moisten the layers lightly for better compaction.
Useful tips for a solid foundation:
- Work in layers of a maximum of 10 cm thick for proper compaction.
- Regularly check the height and slope.
- Wait at least 48 hours after applying stabilized sand before paving.
- Test the compaction with the "walk test": no footprints should remain.
If you have doubts about the subsoil's load-bearing capacity, you can add an extra drainage layer. This is especially useful in areas where the groundwater level is less than 1 meter below the surface.
Laying Cobblestones
Choice of Pattern
When choosing a pattern for your cobblestone driveway, consider both appearance and practicality. Below are the most commonly used patterns with their characteristics:
| Pattern | Strength | Suitable for | Difficulty level |
|---|---|---|---|
| Herringbone | Very high | Heavy traffic | Moderate |
| Running bond | High | Normal use | Easy |
| Chevron | Very high | Slopes | Complex |
| Block pattern | Average | Light traffic | Easy |
The herringbone is ideal for driveways due to its good weight distribution. Lay the stones at a 45-degree angle to the driving direction for maximum stability. Once you've chosen a pattern, you can start laying the cobblestones.
Placing the Stones
A strong foundation is essential before you start placing the stones. Start at a straight edge or facade to align everything neatly. String lines help maintain tight lines, and check regularly with a level.
Important tips during placement:
- Leave a joint of 3-5 mm between the stones and lay them 1 cm above the desired height.
- Work in sections of a maximum of 5 m² to keep an overview.
- Regularly check the dimensions with a straightedge for a neat result.
- Use a rubber mallet to gently tap the stones evenly.
- Compact only after finishing a section to secure everything firmly.
Technical points of attention:
- Ensure a slope of 2% for proper water drainage.
- Place edge stones 2 cm higher than the street surface.
- Use edging bands at least 6 cm wide.
- Keep a 5 mm gap between the edging band and the cobblestones.
Work step by step and regularly check if the stones fit well. If something isn't right, you can easily correct it by gently lifting the stone and adjusting the sand bed. This results in a neat and durable final product.
Finishing and Maintenance
Filling Joints and Surface Finishing
After laying the cobblestones, it's important to fill the joints with fine jointing sand or polymeric sand. Polymeric sand has the advantage of hardening on contact with water, reducing the chance of weed growth.
| Jointing Material | Advantages | Disadvantages | Lifespan |
|---|---|---|---|
| Fine jointing sand | Inexpensive, natural | Requires regular refilling | 1-2 years |
| Polymeric sand | Durable, prevents weeds | More expensive, not reusable | 5-7 years |
| Cement-sand mixture | Very strong, waterproof | Difficult to repair | 10+ years |
Steps for filling joints:
- Evenly spread jointing sand over the cobblestones.
- Sweep the sand into the joints with a soft broom.
- Use a rubber compactor to allow the sand to settle well.
- Repeat these steps until all joints are completely filled.
Regular Maintenance
A good finish is important, but regular maintenance is equally crucial to ensure the longevity of the cobblestones. Set up a maintenance plan with the following actions:
Weekly or monthly:
- Sweep the cobblestones to remove dirt and leaves.
- Check for loose stones or subsidence.
- Remove any weeds from the joints.
Seasonal maintenance:
- Spring: Clean thoroughly with a pressure washer (max. 60 bar).
- Summer: Check the joints and refill if necessary.
- Autumn: Remove extra leaves to prevent buildup.
- Winter: Prefer coarse sand over rock salt to prevent damage.
When using a pressure washer, it is wise to hold it at a 45-degree angle and not point it too closely at the joints. This keeps the jointing material in place. For stubborn stains, you can use a special cleaner that is safe for cobblestones.
To further protect your driveway from moisture, dirt, and moss growth, you can apply a water-repellent sealant every 2-3 years. Choose a product suitable for natural stone and follow the instructions on the package.
