Less expensive than an asphalt or concrete driveway, crushed limestone is often a popular method of material to lay as it is also quite aesthetically pleasing.

Making a crushed limestone driveway requires a base of large limestones, and successively laying smaller stones on top. Interestingly, as the jagged edges of crushed limestone bind together when pressed, they create a sturdy driveway with a unique range of contrasting detail.

To do this yourself, all you need is access to a skid-steer loader with a scraper attachment, or small bulldozer – both available to rent. Here we provide a step-by-step guide to installing your very own crushed limestone driveway.

Step 1:

Firstly, utilise a few stakes and some string to mark where you plan to build the crushed limestone driveway, with a minimum distance of 10 or 12 feet for the width. Ensure you take into account any walls, bushes or areas where it may not be suitable for a car door to open and for a person to get out, as well as avoiding dinging the car doors on objects.

A double-lane driveway will require a minimum of 20 feet for the driveway length. For long driveways, plan a minimum of 18 to 20 feet of length for each vehicle you want to park there. Remember to provide extra space for where the sidewalk crosses the driveway when necessary.

Step 2:

Take the layer of topsoil off within the marked stake area with your preferred tool (skid-steer loader or small bulldozer). The topsoil layer doesn’t need to go into a skip – try and re-use the valuable soil elsewhere for gardening or landscaping. Dig until you’re a minimum of 1 foot deep within the staked area of your new driveway.

Step 3:

Now to smooth it. Drive over the area a few times backwards and forwards with your heavy machinery to help pack it in place. You want it to be level, but with a slight slope away from the house or garage area to allow for water drainage.

Step 4:

Cover with weed barrier fabric – easily bought from your local hardware store. Then, cover the fabric area with 4 to 5 inches of crushed #1 or #2 limestone rocks (these grades represent the size of lemons or grapefruits, providing a nice firm base for the driveway). Work them into position with your heavy equipment’s scraper blade attachment.

Step 5:

Now, put a second layer of ping pong-sized #57 crushed stone 4 inches thick. Position them along the driveway with the scraper blade attachment. Use a heavy roller that attaches to your heavy equipment to pack the stones tightly in place.

Step 6:

Finally, top your limestone driveway with a 4 to 5-inch thick layer of #8 crushed limestone. Arrange the stones like a crown along the length of your driveway so it’s higher than the sides. This will help water to flow better off the driveway. After packing the stones with the roller, you should easily be able to walk or ride a bicycle over it.
