How to Add Gravel or Stone in Between a Concrete Driveway

Calculate how many stones and how much weed cloth you need by figuring out the square footage of the area. Measure the area's length and width. Multiply the two figures together to get the total square feet. For instance, one ton of 3/4-inch stone laid two inches deep covers 120 square feet. Stone laid three inches deep covers 80 square feet. Stone applied four inches deep covers 60 square feet.

Remove about three to four inches of soil between the concreted areas. Use a shovel to dig the soil from the area, placing it into a wheelbarrow for easy removal. Rake the area relatively level using a hard rake.

Pack the soil down by walking back and forth over the area. Water the ground to pack the soil down even further, if needed.

Cut the weed cloth to fit the area according to your length and width measurements. Adding a bottom layer of weed cloth keeps the stones in place. This procedure ensures the stones do not sink into the soil, which would force you to replenish the stones more frequently.

Lay the weed cloth flat in place on the ground between the concrete. Place a handful of soil on each corner to hold the cloth in place.

Pour the stones upon the weed cloth. If you pour the stones in three equally spaced areas instead of pouring them into one pile, you will make the process of spreading the stones easier.

Rake the stones in place using a hard rake. Spread them evenly across the area, keeping the stones lower than the concrete to prevent them from spilling onto the driveway. Sweep any loose stones back into the rock bed.
