How to Fix Potholes in a Limestone Driveway
- 1). Move the limestone gravel to an area near the driveway. Loosen the crushed limestone surrounding the pothole using a pickax or shovel. Excavate the pothole area to make a longer-lasting repair.
- 2). Pour limestone gravel into the enlarged pothole until the hole is even with the adjacent area. A gravel driveway performs best with a crown in it – a center area that is slightly higher than the sides so water can flow off it. Add or remove gravel to make your driveway conform to the crown shape.
- 3). Tamp down the rock using a hand tamp or a tamping machine, which you can rent at a hardware store. This compacts the limestone gravel, creating a durable hard-packed driveway. When you finish tamping, the driveway should still have a crown shape.
- 4). Add more limestone gravel and re-tamp. Continue to top off the gravel and tamp down the stone until you've created a level grade once more.
- 5). Fix additional potholes the same way.
