Cobblestone is made hand cut, densely compressed stone and lava made deep under the Earth’s surface, so a cobblestone driveway can last many lifetimes. Cobblestone is one of the most durable stones on Earth, and is used for building houses, walls, patios, driveways and more. Cobblestone, aside from being so durable, is also considered as one of the most beautiful additions that can be made to your home.

Real cobblestone pavers, often called Belgian block, are made of granite and typically measure 4 to 5 inches thick, 7 to 9 inches wide, and 9 to 10 inches long. A paver edge looks best if it is installed along both sides of the driveway, but you can do just one side if that suits your needs. It’s usually best to set the pavers on-edge rather than flat.

Use a screwdriver to pry up the damaged stone. Check the surface underneath and add sand or gravel if it needs to be leveled.

Step 2 – Reinstall the Stone

Put the replacement stone in place. Check to be sure it is level with the surrounds stones. Then, sweep some sand into the cracks around it.

Sunken Areas

Areas of a cobblestone drive can become sunken in due to problems with the underlayment.  This can be a more extensive repair, depending on the size and depth of the area.

Step 1 – Remove the Stones

Remove all of the stones from the sunken area. Remove some stones in a perimeter around the area as well so that you can more easily level the edges. Inspect the underlying surface. Make sure there are no drainage problems.

Step 2 – Fill in the Area

Fill in the area with gravel. Wet it down thoroughly. Now add some concrete sand on top. Use the plate compactor or a hand tamper to level the area.

Step 3 – Reinstall the Stones

Now place the stones on the new base and fit them in tightly. Once the stones are laid, sweep in some new sand around them.


If the cobblestones have become unsightly by leaking auto fluids, algae or other kinds of discolorations, you can easily clean them.

Step 1 – Preparation

Mix water with the TSP (see the recommendations on the box) and load it into the power washer. Test the washer on a lower power setting and turn it up gradually until it removes the discoloration.

Step 2 –Wash

Now that you know the correct setting, turn on the power washer and go over the cobblestones. You may need to hold the nozzle at different angles to get all of the debris off of the cobblestones. Don’t forget to clean the curbs and driveway apron.

Step 3 – Rinse

Now fill the power washer with clean water and rinse the cobblestones thoroughly.
