SYSTEM CAPABILITY

What the system can do and what one completed object did are different quantities, so they stay in separate columns.

PARAMETERSYSTEM CAPABILITYCOMPLETED PROJECT
SLOPE STEEPNESSup to 1V:0.5H≈63°1V : 0.75H
HEIGHTby designset by soil, loads and engineering calculation21.6 mtwo benches, 10.0 m and 11.1 m
REINFORCEMENTHG-U geogriduni-axialL = 11.0 / 20.0 m0.5 m spacing

Values depend on soil, fill, groundwater, loads and engineering calculation.

Number of reinforcement layers, reinforcement length, slope steepness and drainage detailing are determined by project-specific design.

Reinforced Soil Structures

Reinforced soil walls and slopes: reinforcement design, facing systems and construction technical support.

Modular Retaining Wall

Retaining wall of precast modular units with geogrid cast into the unit, backed by a reinforced soil mass.

Steel Mesh Faced Reinforced Soil

Reinforced soil structure with steel mesh facing panels and rock fill.
