Adding gravel to your driveway may present a cost, although it might not be necessary to gravel the whole thing. If you have several low spots in your driveway, it would be very beneficial to at least fill those areas. This will help in preventing the water from filling in the low spot next time it rains. By filling low spots with gravel, it will even out the area, and the gravel allows the rain water to run off, instead of getting trapped. Adding gravel will also provide more traction when driving over it.
Once you address all the low spots and any holes in your driveway, creating a crown is a great way for efficient water drainage. This means that the middle of the driveway is the highest spot. You can build up the middle by adding several inches of gravel to the center of the driveway. By creating a crown, you will encourage water to run off the sides and into the ditch.
After adding all the gravel necessary, it’s important to compact the gravel. This way, when you drive over that area, it wont cause shifting of the stones or create more low spots. You can compact the gravel with a plate compactor, tamping bar, or heavy duty roller.
