Light-weight, easy to install and structurally sound

G-Force Segmental Retaining Wall

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)

PHYSICAL CHARACTERISTICS

Compressive Strength 5050 psi (35 MPa)

Water Absorption (max.) 9 lb/ft3 (144 kg/m3)

Freeze-Thaw 1.0% max. loss of mass after 100 cycles1.5% max. loss of mass after 150 cycles

Dimensional Tolerances

Height: + 1/16 in. [1.5 mm] Length & Width: + 1/8 in. [3 mm]

Note: Meets and exceeds the requirements of the ASTM C 1372 Standard Specification for Dry-Cast Segmental Retaining Wall Units.

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.
