How to Make a Driveway Addition

Building an addition on a driveway allows you to accommodate more vehicles. This is a challenging do-it-yourself project because it calls for building a foundation equal in strength to the original driveway, as well as matching the new surface with the old one. Plan to spend at least one weekend building the foundation and laying the pavement, depending on the size of the driveway you’re expanding.

Instructions

    • 1

      Measure the area you want to expand with measuring tape to ensure it will be large enough to accommodate your needs. Mark the area with lawn stakes and connect them with a length of string.

      Dig up the area with a shovel. Re-plant grass in bare spots in your yard, and use the soil to fill in any low-lying areas. Measure the depth of the site with a measuring stick. Continue digging until it has a depth of 1 foot. Dig down an inch more with every 4 feet of distance to slope the driveway addition away from the house.

    • 3

      Press a manual tamper over the bottom of the hole to make it firm for the base.

      Scoop crushed rocks into the hole with a shovel and spread them out. Continue adding the rocks until you have a layer about 8 inches thick. Press them down with the tamper until you cannot pack them down any more.

    • 5

      Fit metal-edge restraints against the inner walls of the site. Secure them down by hammering 12-inch lawn spikes downward through the pre-cut slots along the bottom of the edging restraints.

    • 6

      Spread an inch of sharp grit sand over the rocks with a rake.

    • 7

      Fit pavers over the sand beginning at the side adjacent to the driveway. Continue the existing pattern so the driveway has a seamless look. Set them flush beside each other with minimal spaces in between.

      Pour polymeric sand over the addition once all of the pavers are laid. Press it into joints with a stiff-bristled brush to pad the pavers and keep them in place.
