Kerbs, also known as curbs in the United States and Canada, are concrete stones that provide a decorative and supportive edge to an area of paving. Kerbs are easy to lay and have many practical applications. You can use them to frame a new driveway or set a limit for paving a concrete deck on a wide expanse of lawn. Regardless of how you want to use kerbs, rest assured that you can set them yourself with beautiful results.

Things you need
Clear the area to be covered in concrete or other paving material. Make sure to keep the height and width of the kerb in mind when clearing space.
Pour a line of concrete along the path you want the kerb to follow. The concrete should be 2-inches thick.
Tap down one kerbstone at the beginning of the concrete line, with the rounded, upper edge of the stone facing in towards the paving.
Place another kerbstone at the end of the line of concrete in the same way.
Run a piece of string from the first stone to other one at the end of the line. This string will help you keep the stones level.
Place kerbstones along the length of the concrete row. When you reach the second to last stone, you may have to remove the last one and cut it to the correct length.
Remove each stone, one by one, when they are all placed correctly.
Apply a good quantity of concrete to the front and back of each stone.
Spread the cement thickly on the back of the stone, almost until the top edge. The thickness of the cement should taper and lessen as it goes toward the top, with thickest part at the base.
Put concrete on the front of the stone. You should cover the lower 1/3 portion of the stone in a thick layer.
Replace the stone and gently tap it with a mallet until it is firmly in place.
Check that the tops of the stones are running flush with the string you ran between the first and last stone.
Let the cement cure for at least one day.
Tips and warnings
- Plan to apply new turf and soil along the back of the kerb to cover the base of concrete.
- Don’t skimp on concrete or your kerbstones can become loosened or damage in heavy storms or when struck by a wheel.
