Gravel driveways, especially those that sit on an incline, can have problems with erosion. Rainfall and water run-off from gardening can erode the soil underneath the gravel and weaken the underlying structure. Gravel can also roll down the driveway and create an uneven driving surface. Keeping the gravel driveway from experiencing problems with erosion will ensure that it stays in good condition and remains safe for cars to drive on.
Things You'll Need
Crusher run gravel
Use crusher run gravel to create the surface of the driveway. According to the Vermont Agency of Natural Resources, crusher run gravel will form a more compact surface and resist erosion.
Apply gravel properly, forming a crown in the center of the driveway that tapers out to the sides. This will help divert water along the sides of the driveway and reduce erosion.
Install water bars along the driveway at 30-degree angles to the road. A water bar is a cross section of the driveway fortified with treated lumber and rebar spikes that helps to divert water to the sides of the driveway.
Dig trenches along the driveway to catch runoff water and prevent erosion. Line the trenches with gravel or vegetation to help divert the water or absorb it and stop it from eroding the soil beneath the driveway.
Plant absorbent trees and shrubs along the driveway to help soak up excess water and prevent it from creating runoff channels and erosion.
Fill in any grooves or channels in the driveway as soon as you notice them to prevent them from becoming deeper. Add fresh gravel each spring.
