Paver Preparation

To install concrete pavers for a walkway or patio, install over a packed base material. The prep work is the most important part of your walkway or patio. First, excavate approx 6” of soil from the area that you are going to apply the pavers. Install approx. 5” of crushed Limestone, or a Class 5 gravel, level it off, or screed it to your preferred slope, and tamp with a vibrating tamper. If it is a smaller area, you can also use a 8” or 12” sq hand tamper. This provides a stable and sturdy base for your pavers. The next step is to install 1 inch of sand. The best method for this is to get some proper lengths of 1” diameter pipe, pvc or metal, and lay it in parallel to each other, then dump the sand over the area, using the pipes as screed planes. This will produce a consistent thickness of sand.

Now you are ready to place the pavers. Some cutting may be necessary, so you will usually need chisels and a saw or grinder to cut the stones to fit. Once the stones are laid as desired, use a dead blow hammer to tamp the stones so that they are solidly set into the sand. Once you have the pavers in place and secure, sweep the excess sand from between the stone, and make sure the stones are dry. Sweep in the “Gator Sand”. This is a sand either Gray or Tan, that has a polymer added to it. Sweep the sand into the joints, filling up the joints. Run a vibrating tamper over the pavers, and refill as necessary. Make sure you sweep all of the excess Gator Sand off of the stone, and fill the joints. Apply a “rain” or mist of water, allowing water to fall onto the entire patio. Make sure you don’t spray directly onto the joints, because this will allow the polymer sand to get sprayed out of the joints and onto the surface of the stones. This is a bonding type of sand, and it will stick to the stones surface if allowed to dry. It will not come off very easy. Allow it to dry for about 3 days, and you will have a patio that is very solid, almost like concrete! The polymer that is in the sand binds the stones together, yet stays flexible to allow for frost heaves in the winter. If more sand is needed, it can be added anytime later, and it will bond together.
