INSTALLATION | Keystone 133Elite Units
|
STEP TWO: Install the base course.
|
| Place the first course of Keystone 133Elite units end to end (with face of wall corners touching) on the prepared base. The receiving channel on the unit should be placed downward and the pin holes should face upward, as shown. Make sure each unit is level. Leveling the first course is critical for accurate and acceptable results. Minimum embedment of the base course should be 8" below grade. |
