Reinforced soil wall method/Reinforced embankment method
ADEAM Unit Cap Construction Method and Green Terrace Wall Method
Outline
Create a slope in harmony with nature,
considering the global environment
The ADEAM Unit Cap Construction Method and Green Terrace Wall Method make reinforced soil wall which connects the “ADEAM” installed in the embankment and the wall surface material (slope unit). It can be applied both of reinforced soil walls with slopes steeper than 1: 0.6 and more gentle slope than 1: 0.6. The wall surface material has a slope unit and unit caps in order to prevent the wall from buckling or rotation. Since they can use various range of embankment materials, it is possible to use locally generated soil effectively. Furthermore, because the wall surface can be greened, the surface temperature of the wall can be suppressed lower than that of concrete structures such as retaining walls, and it is attracting attention as a global warming prevention method now.
Green Terrace Wall Construction Method is a construction method that connects ADEAM with the steeper gradient wall surface materials than the slope surface and layers them in staircase pattern. It can be applied to various slopes by adjusting the width of the staircase.

Slope unit
inclined wall surface unit(Wall surface material for steep embankments). It strongly restrains the embankment and stabilizes the slope. Vegetate by installing a vegetation sheet with a reinforced restraint net.
