How to Retain Gravel on Driveways

Building a driveway is a time-consuming and often expensive process. Gravel provides a low-cost alternative to other types of driveways. This low cost usually only reflects in the initial cost of the paving material, however. Gravel driveways require annual or more frequent maintenance because the gravel layer sinks into the ground and spreads out of the driveway site. Retaining gravel on your driveway through the use of small retaining walls on each side of the driveway helps you to save money on driveway maintenance costs.

Extend the life of your driveway and cut down on maintenance costs.

Step 1

Measure the width of the edging blocks you chose for your short retaining walls on either side of your gravel driveway. Use this width measurement to dig a similarly sized trench directly outside the perimeter of the driveway.

Step 2

Dig a 3-inch deep trench using a spade to remove only the soil. Place the soil and sod in a wheelbarrow or bucket to transport away from your work site as necessary.

Step 3

Set the first layer of the retaining wall into place at the bottom of the trench. Set edging blocks end-to-end inside the trench, leaving little or no gap between the blocks. Put the first layer or course of blocks into place before building the height of the walls.

Step 4

Apply a liberal amount of masonry adhesive to the bottom of each edging block for the next layer of the retaining walls. Set the blocks into place over the first layer, staggering the second layer slightly from the first layer to create more durable retaining walls.

Step 5

Continue to place layers of the edging pavers until you build the retaining walls to the desired height. To retain gravel on your driveway, the walls need to measure between 6 and 10 inches from the ground.
