Rock Driveways - How to Patch Up Holes Rock Driveways - How to Patch Up Holes

What You'll Need
Plate compactor

Rock driveways are charming and simple to build on your own. However, they can sometimes develop holes from the pressure of passing vehicles and erosion. You can patch these holes on your own. You will need to use a plate compactor. You can rent a plate compactor from your local home improvement store. When repairing the hole make sure that you have rock that matches the existing driveway on hand.

Step 1 - Clean Out Hole

If the hole is full of debris or mud you want to try and remove as much of that as possible. It is best to patch the holes in your rock driveway when the weather is dry and has been for a few days. This will ensure that the holes aren’t full of water.

Use the shovel to dig down as far as possible. If you have landscaping fabric under the rocks, continue to dig until you see. By digging the hole out to the bottom you can make a sturdier repair.

Step 2 - Add Large Rocks

Areas that get a lot of pressure from vehicles on the road will need to be fortified. Therefore, you will need to place large, fist size, rocks at the bottom of the hole. It is best to actually build your entire driveway in this manner. If you haven’t done so, however, use the large rocks on the bottom of the hole. Remember that the rocks that you use for your driveway should not be round. If you have used round rocks on your driveway, this may be the reason why you have holes to begin with. The round rocks don’t lock together and move when hit with the pressure from passing vehicles.

Step 3 - Level the Area

With the large rocks on the bottom of the hole, add another layer of smaller rocks, about the size of ping pong balls. If you built your own rock driveway, you should have followed a similar layering procedure.

Add a layer of rock on top of these 2 layers. The third layer should be whatever type of rock you have on the top of the rest of the driveway. Building the driveway in layers creates a stronger foundation that is less susceptible to movement.

Try to fill the hole so that it is a little bit higher than the rest of the driveway. You are going to compress it and you don’t want it to be depressed. 

Step 4—Compact the Driveway

Using a plate compactor, you should compact the entire driveway. You want to make sure that the hole that you filled is level with the rest of the driveway. If you find that after compacting the driveway the patched area is a bit depressed, fill with more of the topping rock and compact it again. 

That’s it. You can patch the holes in your rock driveway rather easily. If you check the driveway periodically, you should be able to catch the holes before they require such an extensive repair.
