FEATURES & BENEFITS
• Optimized weight to achieve low shipping cost and maintain structural integrity
• 3.9° battered wall system to reduce active earth pressure
• Tapered units allow for straight or curved walls
• Easy installation
• Modern appearance
• Variety of colors
• Cap and corner units available (sold separately)
APPLICATIONS
• Suitable for commercial, industrial, institutional and residential applications
• Construction of gravity retaining walls (without geogrid reinforcement) up to 3’- 4” (1m)1 (including embedment)
• Construction of intermediate to high MSE (Mechanically Stabilized Earth) wall systems
• Stairs, planters and terraced patios
Notes: 1. Maximum height under optimal conditions (no surcharge, no slope, good drainage and a gravel retaining soil)

DESIGN DATA
Horizontal Setback 9/16 in. (14 mm)
Infilled Unit Weight 122 pcf (19.2 kN/m3)
Infilled center of gravity (measured from the face of the unit) 5 7/16 in. (138 mm)
Block Shear Strength(ASTM D 6916)
Vub[lb/ft] = 545 + N*tan(38) ≤ 3826 Vub[kN/m] = 7.95 + N*tan(38) ≤ 55.8
Block -Geogrid Shear Strength (Miragrid 3XT) (ASTM D 6916)
Vug[lb/ft] = 445 + N*tan(36) ≤ 3496 Vug[kN/m] = 6.49 + N*tan(36) ≤ 51.0
Block - Geogrid Connection Strength (Miragrid 3XT) (ASTM D 6638)
Tc[lb/ft] = 1640 + N*tan(18) ≤ 3005Tc[kN/m] = 23.93 + N*tan(18) ≤ 43.8
Note: The infilled unit weight shown here is based on an assumed aggregate unit weight of 96.8 lb/ft³ (1550 kg/m³ ) used to fill the core cavity of the block and the space between adjacent blocks.
