Ecological balance
Usually retaining walls are constructed of reinforced concrete, if an impermeable surface is not desired, it would be a sensible solution to create a filling area (but not for dam constructions). Choosing the ground reinforced with geogrid reinforcements instead of reinforced concrete retaining wall will also contribute to the ecological balance. While reinforced concrete wall surfaces cannot be vegetated, the surfaces of filled areas reinforced with geogrid reinforcements can be vegetated. ==References==
