Lay the garden hose in the yard to determine the outline and size of the area that you want to pave. Mark the outline of the pathway with wood stakes placed every 4 feet. Tie the stakes together with string for a rough outline.
Lay out the octagon pavers across the width of the pathway with border edges on all sides to ensure the pavers fit perfectly inside the marked area. Adjust the width as necessary.
Measure the depth of the paving stones. Add 4 inches to this measurement and dig out a trench between the wood stakes equal to this measurement. Usually 6 or 8 inches is an appropriate trench depth. Use a large level to level the trench. Tamp the ground down firmly.
Pour 3 to 4 inches of crushed rock into the trench. Use the tamp to pack the stone down firmly.
Stake plastic edge restrains along all side edges of the pathway or patio. This will prevent the pavers from escaping.
Pour a 1 ½ inch layer of sand over the crushed rock.
Set the border pieces of the pavers in place along all edges. Fit the octagonal pavers between the border pavers. If necessary, trim the edges of the border pieces with a masonry saw to achieve a perfect fit. Mark the cutting line with chalk, then wear safety goggles and a dust mask as you make the cut. Set the whole pavers in place and the cut pavers last.
Compress the pathway with a plate compactor to set the pavers in place so they will not shift or move. Pour sand between the joints of the pavers to prevent the growth of weeds.
