REINFORCED SLOPES/WALLS
Reinforced Soil Slopes (RSS) are compacted fill embankments that incorporate the use of horizontal placement of geosynthetic reinforcement to create a stable, oversteepened slope structure. Oversteepened slopes often require facial geosynthetic wrap and wire forms for erosion control and constructability at the slope face. Below are two typical face treatments, vegetation face and stone face, with the appropriate products shown supplied by Earth Wall Products. The face wrap for soil vegetated slopes FW24 is UV stabilized to provide important sunlight protection until vegetation is established. For a stone faced structure, we provide a Biaxial geogrid face wrap with extra carbon black for UV protection.


REINFORCED SLOPES DETENTION/ RETENTION
- Typical setback for vegetated slopes is 1H to 3V
(6” setback for every 18” WWF Basket) - Less expensive facing element per SF
- More forgiving with settlement and easier to construct
- Used for slopes and utilized in detention/retention pond applications
- Retention/Detention hot-dipped or electrogalvinized baskets are available in areas where water would be present


DOT TEMP WALLS
- Typical zero setback or vertical alignment
- Less expensive facing element per SF
- More forgiving with settlement and easier to construct
- Used for temporary support of roadways during elevation or vertical curve highway geometry changes
PRESSURE RELIEF
- Typical zero setback or vertical alignment
- Less expensive facing element per SF
- More forgiving with settlement and easier to construct
- Used to support horizontal soil pressures to allow below-ground structure in front of pressure relief wall to not experience lateral loads

COMPONENTS OF REINFORCED SLOPES/ WALLS
- WWF
- Struts
- Biaxial Grid Face Wrap
- FW 22 and FW24 (Higher UV Protection)
- Stone (Water Applications) typically used to backfill the welded wire form use a BX geogrid to contain the stone
- A uniaxial geogrid (such as HTG) is utilized to reinforce the soil as with any MSE structure
