8 EASY STEPS TO LASTING BEAUTY
These
are typical directions for a retaining wall Ask your dealer for further information. |

1. PLANNING Mark a line where the front of the wall will be. Measure lengths and heights of each section. If necessary, contact local utility companies for the location and depth of pipes and cables. For an estimate of quantities, refer to the estimating chart at the bottom of this page. |
2. EXCAVATE Remove soil to create a trench 8" deep and 16" wide. Shape slope to allow for 6" of drainage material behind the wall. |

3. PREPARE BASE Compact base and ensure native soil is stable. Place filter cloth on the base and up the exposed face of the excavation. Fill trench with well graded angular gravel and compact to a depth of 4". |
4. FIRST COURSE Split units apart at the splitting groove. Position a level string line to mark the location of the first course. Place the first course of units on the prepared base and ensure the unit is level front to back and side to side. |
|
5. STACK UNITS Sweep off and place next course of units in a running bond pattern. The middle of the unit is approximately above the joint between adjacent blocks below. |
6. BACKFILL Fill behind the wall with 3/4" free draining rock. Compact in 6" lifts. Place soil in front of the wall to ensure that one unit is completely buried. Stack more units and backfill until the desired height is achieved. |
|
7. SECURE COPING On the last course of wall units place a line of adhesive on both sides of the tongue. Place coping unit on top and apply pressure to secure. |
8. FINISH GRADING Pull filter cloth towards wall and place 6" of soil on top. Slope the soil above and below the wall to ensure water will flow away from and not accumulate near the wall. |
