Curbing makes for tidy edges on gravel driveways. Usually gravel and lawn together leave a messy edge that looks unkempt. With a curb edge, the gravel can be kept weed-free with the defined separation from the lawn. Harrowing and spraying are both good strategies for keeping weeds down in the gravel area, and the lawn can be lush and green right to the edge.
Light duty curb like mower edge, flat top or low angle border are more vulnerable to show removal damage. If you are using a machine with a blade, they are not recommended.
5X6 curb is best for gravel driveways. we generally install it with pins driven into the base, and with horizontal steel reinforcement. This makes it tougher for snow removal activities.
Driveway edging can be damaged by driving over it with heavy vehicles. It can generally handle light bumps from cars.
When pinned onto an asphalt surface, even light duty curbing is very tough. We have used it in condo complexes to trim all the asphalt, and it has proven quite durable even in narrow areas.
