Our 4-step process to gravel road repair has proven to be MUCH more effective than just topping off the road with new gravel or grading with a blade.
Winter weather, snowplowing, spring thaws and summer rain all combine with automobile traffic and take a toll on gravel roads. The common theme is that water coming out of the ground as frost or summer rains wreaks havoc on gravel roads.
That’s why the Fix My Gravel Road team has developed a time-proven technique of four key steps to get your road or driveway back in shape.
1) Break up the potholes
The first step is to break the surface and potholes up. Just filling in potholes with gravel is like cooking with a teflon fry pan, the food will not stick and neither will the gravel due to the compacted material in the pothole. Just filling it with gravel will cause the problem to reoccur in one to two weeks, depending on traffic. The only way to permanently eliminate a pothole is to dig it up completely and fill with gravel that is compacted in layers.
2) Establish a crown
The second step is to establish a crown in the road or driveway for water to properly drain to the side, usually at a 3 – 4 degree angle slope on both sides of the centerline. Standing water that pools on the road is a recipe for potholes. If the road is below grade at the side, create a ditch along the side of the road will facilitate water drainage. In a worst case scenario, the only way to fix the drainage problem is to increase the height of the road by adding new gravel.
3) Compacting the roadway
The third step is to put the finished grade on the road or driveway and to compact it with a Vibratory Compactor, which uses 7,000 pounds of pressure to compact the road and potholes. You may see divots where the pothole(s) kept repeating over time. It’s important to continue the grading/compacting process until the surface is flat and no divots are visible.

4) Final grading
The 4th Step is to perform the final grading to correct any remaining unevenness. Also, a homeowner may want to add gravel to increase the curb appeal, or if the road or driveway surface is below grade we will apply gravel with a limestone binder.
When these four steps are followed properly, your road or driveway will last much longer, and you’ll see less pothole recurrence.
