Follow these procedures accordingly to ensure properly installed pavers:
Prepare the ground where you will install the pavers.
Clean the area where you wish to lay your pavers. Make sure that no root, weed, stone or other unwanted material is present on the ground. They will only make the surface bumpy and irregular. Once the surface is even, excavate a depth of 7” from the ground. You also have to add approximately 12’ on your overall paving area.
Put the base material and compact it.
Install the first layer using some gravel or coarse sand. You need to tamp this layer with a plate compactor which you can rent from a builders store. Repeat the layers until only 3” of the total excavated ground remains. Don’t forget to compact the layers.
Place the edge restraints around the perimeter of the paving area.
Edge restraints act as barriers that keep the pavers from moving and spreading. There are different types of restraints such as PVC, concrete, wood and aluminum. You can use any of these and install them around the paving area.
Install and screed the bedding.
Put screed rails, 1” in diameter each, on the surface. Then, place some bedding sand around each screed rail and fill every visible low spot. When the surface is already even, remove the screed rails and compact the area.
Lay your interlocking pavers.
Start laying the interlocking pavers on the corner. The pattern depends on your own design but make sure that you are putting the pieces in a balanced way. Also, you have to leave gaps between each interlocking paver.
Cut excess parts for a more balanced look – Use a chisel or a saw and cut the sides of the pavers. Then, compact the area and remember to make a few passes throughout the area.
Let everything settle and do some finishing – Let the pavers settle for some time. After this, sweep the excess sand away from the gaps and the surfaces.
