arbor step 1 GW step 2
STEP 1 | Prepare the site. STEP 2 | Set the base course.
Start by digging a shallow trench 4" deep by 12" wide. Cut through and remove any sod, roots or large rocks. For organic loam soils, dig 4" deeper and add a leveling pad of sand or gravel. Compact and level the soil to receive the first course of Keystone Garden Wall. Place and level the first Keystone Garden Wall unit. Level each additional unit on the base course as you place it,making sure that the outside edges touch. If your wall contains both straight and curved areas, start with a straight area and build into the curves. Complete the base course before proceeding to the second course.
Gw step 3

Remove Lugs: To remove outside lugs or edges of the retaining lip, hold the unit securely or place it at an angle on the ground. Strike the lug firmly with a hammer. Cutting the units may also be necessary to keep them on bond. Always wear safety glasses to protect the eyes from chips.

STEP 3 | Stack and fill.
Starting with straight areas first, begin placing the second course. Center each Keystone Garden Wall unit on the seams of the course below in a running bond pattern as shown. Now proceed to the next layer, backfilling as you go. For drainage behind the wall, clean gravel or crushed stone is recommended.
