    Step 1

    Prepare the Base
    In this lawn, there were 2 different bases listed below the cobbles. Part of it was existing concrete, and the other part had previously been pavers. On the concrete, the only prep work that needed to be done was a basic pressure wash. For the area beyond the concrete that formed an extension, base rock was brought in to form a solid structure (Image 1). The base rock was laid down so that it actually rose about an inch above the existing concrete, then a gas-powered compactor brought it down so it was just a little higher than the concrete (Image 2).

    If you are starting in a bare soil area, dig down to give yourself a couple inches of base and allow for half the height of the pavers to determine your last patio height.

    Step 2

    Include Sand
    Put sand over the whole area and utilize a rake to spread it out about an inch thick. This will certainly form a cushion for the cobblestones.

    Step 3

    Lay Cobblestone Pavers
    The various colors and styles of pavers consist of straight, round and fanned-out designs. For the straight type, start at one end and lay them on top of the sand in straight rows, working your method to the other end of the space. Making use of wire snips, get rid of the two smaller cobbles at the end of each mat of pavers so the mats fit together. At the end of the row, leave the smaller pavers on the mat to function as a straight edge.

    Step 4

    Condense the Pavers
    Do not make use of a compactor over pavers that have actually been laid on top of concrete. If you have laid them on top of base rock however, lightly spray the cobbles with water and go over them with a compactor. This will push them down into the base rock but not all the way.

    Step 5

    Mix the Grout
    For this job, we made use of a special type of epoxy that, when blended with sand, produces a grout that solidifies once it dries.

    Utilize a portable cement mixer to mix the grout. Pour in one bag of sand, the color of which will certainly be the last color of the grout. Then add one container each of the two-part epoxy. Lastly, fill each of the containers with water and add that to the mixer also. Pouring the water into the containers permits you to determine properly as well as to utilize any remaining epoxy.

    Let the grout mix for about three minutes, up until the consistency resembles pancake batter.

    Step 6

    Pour and Spread out the Grout
    Wet down a wheelbarrow (so the grout won’t adhere to it) and gather the grout. Make use of a foam squeegee with a broom handle to spread the grout, filling out all of the gaps in the cobbletone. It solidifies in about 10 minutes.

    When you have most of the grout spread into the gaps, go over the same location with another squeegee to clean the continuing to be grout from the top of the pavers. When you’ve finished the entire location, use a stiff-bristle push broom to clean up any remnants again. Let the brand-new cobblestone patio dry for five hours before strolling on it.
