Ever Wonder Where Potholes Come From?


Ever drive across a gravel or dirt road with potholes so bad your head hits the roof? How many times have you filled in a pothole only to have it reappear days later? These are symptoms of poor water drainage caused by a rain or snowmelt. See before (left) and after (right) photos above.

What’s a person to do?

First and foremost, the center of the gravel road needs to be flattened and a “crown” needs to be established to allow for proper water drainage. A crown can be created by sloping the road from the center to the edges approximately 3 degrees or ¼ inch per foot

In order to create the “crown” the road surface needs to be broken up to the depth of the deepest pothole. Then the loose material can then be graded to fill potholes and crown the road. Normal vehicle traffic will compact the loosened material to re-establish a smooth hard surface. The process has the potential to unearth rocks that lie just below the road surface and this is normal. Our finishing/smoothing process is to move these rocks to the edges of the road or driveway.

Depending on the quality of gravel in the road and how deep the potholes are (3 inches in depth or greater) the potholes may reform, but not as deep, as the fill material compacts. This may occur within 15 days of the initial fix. This can be easily rectified via spot fixes using the same process as above.

I have a dirt two track, what can I do?

The process is nearly identical as the gravel road repair. A dirt two track does not have the binders that “Class 5” gravel has. This simply means as the fix is applied, the material compaction process is more extreme than that of a gravel road, and the two track may reappear in as little as 3 days. This is easily rectified by re-grading the road should the homeowner choose to do so.
