Step 1:

Determine wall location. Dig a shallow trench for wall base. Place granular leveling pad material. Compact and level the base pad. Place and level the first course units. If grade changes along base of wall, create stepped leveling pad as required. Always start wall at lowest elevations, working to highest. Complete base course before proceeding with additional courses.

Step 2:

Place a 4” perforated drainage pipe behind 1st course then backfill first course units with clean granular fill material. Compact with hand tamper or appropriate vibratory plate tamper. Backfill and compact behind each course before installing

Step 3:

Starting at straight wall area, place units centered over joint of units below to form a running bond pattern. Build through curves in similar manner. Note: At curves, course bonding will adjust sideways. If stack bond occurs, (seams begin to line up) remove rear interlock lip or cut units accordingly to get back to running bond. Finish the wall with installation of cap units using Keystone KapSeal adhesive.
