1 KEYSTONE COUNTRY MANOR SYSTEM DESIGN CARTS

2 Design Details Design Assumptions Friction angle (PI) for earth pressure calculations of geogrid reinforced walls is evaluated at 26, 0 and 4 only. For other soil type analysis, refer to the KeyWall design software program or consult with a qualified engineer. Moist weight of the three soil types indicated is 20 lb./ft (9kN/m 2 ). Sliding calculations use 6" (52mm) crushed stone leveling pad as compacted foundation material. All backfill materials are compacted to 95% Standard Proctor density. The term vertical is a wall built to a near vertical alignment having a slight positive setback ( +). The information provided herein is for preliminary design use only. A qualified engineer should be consulted for design and analysis of structures. Keystone Retaining Wall Systems LLC assumes no liability for the improper use of this information. Design Notes For low (non-structural) landscape retaining walls, Country Manor/Stonegate can be constructed as a non-reinforced gravity wall as shown in the chart below. This chart is for retaining walls in the near vertical option. Note: use pins and construction adhesive at low border/parapet walls.
