This is a quick reference will provide basic information on building a Keystone® Country Manor Wall. Descriptions of the Country Manor product Line, the required tools, construction methods and design ideas will be at your fingertips.
Keystone® Country Manor offers the appearance of rustic hand laid stone walls with the strength and ease of installation provided by dry-stacked, modular pin-connected technology. Random and rugged, these high-strength concrete units resemble Old English estate walls, adding character to any project.
Correctly assembled, Keystone® Country Manor units will result in unique designs with the texture, color and appearance of hand-laid stone. Walls can be built as low gravity walls or taller, soil reinforced wall structures, capable of handling surcharge loads.
Installation:
I. Excavate the trench
After selecting the location and length of the wall, excavate the base trench to the designed width and depth (min 20” W x 12” D [500 x 300 mm]). DO NOT USE THIS MATERIAL AS BACKFILL. Remove all surface vegetation and debris.
II. Prepare the base leveling Pad
Start the leveling pad at the lowest elevation along wall alignment. Step up in 6” (150mm) increments with the base required at elevation changes in foundation. Level the prepared base with 6” (150 mm) of well-compacted granular fill (gravel, road base, or ½” to ¾” [10-20 mm] crushed stone.
III. Compact leveling Pad
Compact to 95% Standard Proctor Greater
Do not use PEA GRAVEl or SAND for leveling pad.
IV. Set and Align base course
Place the first course of Keystone® Country Manor units end to end (with face of wall corners touching) on the base. The long Groove (receiving channel) on the unit should be placed downward and three 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 6” below grade.
Place the fiberglass pins into the holes of the keystone Country Manor Units (Note: place one pin only per each grouping of 3 holes). Place pins in the middle hole for near vertical alignment or the holes nearest the embankment for a 9.5o +/- setback per course.
VI. Install the Drainage Fill, Backfill
Once the pins have been installed, provide ½” – ¾” (10 – 20 mm) clean crushed stone drainage fill behind the units to a minimum depth of 12” (300 mm). Fill open spaces between units and open cavities/cores with the same drainage material.
VII. Compact Fill
Proceed to place backfill (free draining granular fill) in maximum 6” (150 mm) layers. Compact to a dense, non-compressing state, or with testing, a 95% Standard Proctor Density with the appropriate compaction of equipment.
VIII. Install Additional Courses
Place the next course of Keystone Country Manor units over fiberglass pins, fitting the pins into the long receiving channel recess of the units above. Push the Country Manor units toward the place of the wall until they make full contact with the pins. If pins do not connect with channel, place drainage fill in core to provide unit interlock with pin. Continue backfilling and building to desired top elevation.
IX. Capping the Wall
With units dry and clean, use construction adhesive (Keystone Kapseal) or the equivalent for a mechanical bond. Install the Keystone® Country Manor 3” 975 mm) capping unit, architectural precast concrete or cut stone as a coping element. The cap may be flush or overhanging as required by aesthetics and design.
