Because patio pavers are set at 45-degree angles, the 45 herringbone design seems to invite you to follow the sidewalk or join the activities on the patio. Once you understand the basic concept underlying a herringbone paver pattern, installation should be fairly simple and the base requires only compacted sand.
Set the edge restraints in place along the outer edge of the patio if you are using them. Make sure the corners are square.
Place an outer row of patio pavers in a straight formation against the edge restraints. Set them end to end or side by side depending on your preferences. To help with spacing the pavers, touch the paver to be laid against the side of the last set paver. Then drop it into place instead of sliding it into position. This outer row acts as the boundary for the patio or walkway.
Run a string line in the sand 8½ inches (215 millimetres) from and parallel to the inside edge of the straight row of pavers you just set. This is where the points of the first row of herringbone pavers should be aligned. Keep the string taut when tying it off.
Position yourself so a row of square-set pavers is to your left and ahead of you. Hold a paver, with the top face facing you, vertically in your right hand. Turn it to a 45-degree angle to the left and put the top point directly under the string line with the bulk of the paver to the right of the line.
Set a second paver at a 90-degree angle to the first paver and closer to your body. The long edge of this second paver should be aligned with the short edge of the first paver. The bulk of the second paver should be to the left of the string line: Only the most extreme right point should touch the string line. This creates an inverted V-shaped chevron. Only the extreme left point of the second paver should touch the square-set row of pavers laid in Step 2.
Set the next pair of pavers to form the next chevron by working away from your original position, or above the first pair of pavers. Keep each new paver pair aligned under the string like the first pair. Continue setting pairs of pavers under the string line until you finish the first row or course.
Continue setting all the pavers on the patio, creating full rows before moving to the next one and working in one direction across the work area.
Once all of the rows that can accommodate full, uncut pavers, have been laid, you need to fill in the gaps between the diagonal pavers and the square-set outer row. This is done by laying pavers in the gaps and marking or measuring where the pavers need to be cut using a masonry saw or guillotine cutter. The cut pavers are dropped into the spaces, using the same technique as in Step 2.
Spread coarse sand on the patio and then brush the sand between all the pavers using a push broom. Keep pushing the sand around, ensuring it fills the seams.
Compact the sand and pavers, using the plate compactor. Repeat Step 9 and compact again until all seams are filled and the surface is even.
Plan the paver placement so that the chevrons, or points, of the herringbone pattern point toward the central focal point of the patio.
