1 LANDSCAPE WALLS

2 Raised bed Prevent erosion

3 LANDSCAPE WALLS Level planting areas

4 LANDSCAPE WALLS Limit to 4’ high Course: row of material along the wall

5 WALL LAYOUT Locate the front of the wall and stake Offset stakes to allow room to work

6 BASE PREPARATION Base is ¾” to 1” crushed stone –6” deep –12” wider than wall Vibratory plate

7 BASE PREPARATION The first course will be below grade to improve stability

8 BASE PREPARATION

9 DRAINAGE BEHIND WALLS Wall failure often due to water build-up Weepholes every 6 to 8 feet

10 DRAINAGE BEHIND WALLS Drain tile on walls that exceed 2’ Drainage gravel around drain tile

16 LANDSCAPE FABRIC Fabric placed behind wall Reduce soil movement through material Optional

17 BACKFILL Backfill with soil after every couple of courses

23 Batter is the leaning or stepping back of a wall Stepping: 1 to 2” for each foot of wall height

24 STABILIZTION Batter is the leaning or stepping back of a wall Leaning: ¼” fall from front to back

44 LANDSCAPE TIMBERS 6” x 6” or larger Treated lumber –Railroad ties treated with creosote

45 LANDSCAPE TIMBERS Vertical Construction Trench equal to the height of wall Staggered in height for interest

46 LANDSCAPE TIMBERS Vertical Construction Attach 2x6 along the back

47 LANDSCAPE TIMBERS Vertical Construction

49 LANDSCAPE TIMBERS Vertical Construction

50 LANDSCAPE TIMBERS Horizontal Construction Stacked method Vertical seams line up

51 LANDSCAPE TIMBERS Horizontal Construction Stacked method Install vertical timbers at seams

52 LANDSCAPE TIMBERS Horizontal Construction Stacked method Timbers are anchored with 12” spikes or ½” rebar
