Equipment Needed
broom, chisel, concrete saw, guide string, gloves, rubber mallet, knee pads, pencil, rake, level, shovel, stakes, tape measure, safety glasses, trowel, wheelbarrow
Getting Started
- Layout design on paper
- Estimate required amount of barkman product, well-graded granular base, top soil, filter cloth and masonry adhesive needed (see product estimator)
Getting Started
- Excavate a trench (A) 8″ to 12″ deep and 16″ to 24″ wide along the entire length of the wall
- Compact base soil to ensure stability (B)
- Lay filter cloth (C) under granular base and against the exposed face of the excavation
- Spread 4″ to 6″ layer of granular base (D), compact
- Position leveling string to mark location of the first course
Installing Units
- Lay first course (E) on prepared base (at least 2″ below grade), keep each unit level front to back and side to side
- Place drain tile (F) on prepared base, behind the first course
- Sweep top of first course, place next offsetting course (G), back fill with granular rock on top of filter cloth
- Repeat offsetting courses (H) and back fill until desired height is reached
- Secure last course (I) with adhesive and apply pressure to secure
Installing Units
- 6″ from top of wall, pull filter cloth back towards the wall, on top of back fill (J)
- Fill remaining space with top soil (K) (cover the pulled back filter cloth) to make ground level with wall
- Fill remaining trench space in front of the wall with top soil (L) sloping away from the wall
