Compact & Levelyour footing material. If you are building on unlevel areas you can prepare step downs in increments of the 4" thickness of the Pyzique stone.
Excavate a trench approximately 14 inches wide. Follow this table for trench depth and thickness of the compactible rock foundation.
The First Course
Place the first layer of Pyzique stones smooth side down on the prepared foundation. Use a carpenter's level in all directions and use a string line to verify straightness. Serpentine walls may be built too. Be certain the base course is level and stones lay flat. For micro leveling and to help the stones lay flat, keep a bag of sand handy and use small handfuls to level and stabilize the first course.
Setback Alignment
Set the center side alignment groove directly above the backmost 5/8" set back groove of the stones in the next lower layer. See stones at top of this page. This visual alignment is all that is required for each successive layer of stones. Mat material can be used to filter soil fines that may migrate into your clean granular fill. A flexible drain tube is a competent way to assure drainage from behind your wall. As successive layers are set,syagger the face seams of the stones for interlocking wall strength.
The normal bottom of each Pyzique stone is smooth. Place the bottom up for your cap row. To avoid vandalism, you may want to use a paver grade glue to secure the cap layer to the layer below it. Place a dab of glue on each of the stones that the cap layer’s stones will set on. Stones must be clean and dry for adhesive to bond.
