CC units

Whether for castle or home ... graceful curves, monumental corners and terraced walls are all part of the charm of Country Cottageā„¢ by Keystone. Random and rugged, yet blended with color and character, these high strength concrete retaining wall modules appear as natural stone. Assembly of the varying length Country Cottage units will result in a random layout, with the texture, color and appearance of an old world stone wall.

NOTES:

  • Maximum wall height not to exceed 18"
  • Use clean granular backfill such as gravel or cushed stone for drainage and to prevent soil from leaching through the wall.
  • A commercial filter fabric (stocked by most garden supply stores) may be used when existing site soils are used for backfill.
Country Cottage

Use this guide for estimating the number of Country Cottage units required.
The following figures are estimates based on using 50% large and 50% small units.
Quantities will vary with different wall layout configurations.

WALL HEIGHT
WALL LENGTH (measured at wall face including curves)
5' 10' 15' 20'
3" (1 course) 4L/4S 8L/8S 12L/12S 16L/16S
6" (2 courses) 8L/8S 16L/16S 24L/24S 32L/32S
9" (3 courses) 12L/12S 24L/24S 36L/36S 48L/48S
12" (4 courses) 16L/16S 32L/32S 48L/48S 64L/64S

18" (6 courses) 24L/24S 48L/48S 72L/72S 96L/96S

L = LARGE UNIT Average face area: 10" x 3" = 30 inch (squared)
S = SMALL UNIT Average face area: 5" x 3" = 15 inch (squared)


This chart is based on site conditions which include: a level grade above and below
the wall, granular soil and no surcharge/loads above wall.
Maximum exposed wall height not to exceed 18"

Prepare Base Leveling Pad Install the First Course Install Additional Courses
Start by digging a shallow trench 6" deep by 12" wide. Cut through and remove any sod, roots or large rocks. Add 2-3 inches of crushed stone for a leveling pad. (Do not use sand or pea gravel.) Tamp or compact the leveling pad prior to placing the first course of Country Cottage. You will need to partially bury the base course 2-4 inches below finish grade. Place the first course of Country Cottage units end to end (with front corners touching). Make sure each unit is level - side to side and front to back. Leveling the first course is critical for accurate and acceptable results. Complete the base course before proceeding to the second course. Starting with straight areas first, begin placing the second course. Build the wall up, randomly utilizing the various unit shapes. Try to avoid a repetition of same unit size frequency along a horizontal line. (Some unit repetition is unavoidable.)

TIPS:
  • Unit joints should be bridged by the units above. Some unit repetition is unavoidable.
  • Use clean granular backfill 4" behind the wall for drainage.
  • A filter fabric may be used to prevent soil from leaching through the wall.
