Gabion Facia Units for Reinforced Soil Walls

Gabion facing with a mesh tail that runs back into the fill — building the wall face and the soil reinforcement in one continuous unit.

Face and reinforcement in one piece

What is a facia unit?

A facia unit for a reinforced soil structure is a gabion-type facing box whose base panel continues as a long tail of double twisted mesh. The tail is laid between compacted layers of backfill, so the soil block itself becomes the retaining structure.

Vertical units build stepped or near-vertical walls; inclined units give a sloped, vegetated face at angles from 45° up to 87°. IS 16014:2024 specifies them in PVC coated wire only, because the tail is permanently buried.

  • Taller walls and steeper slopes than gravity gabions alone
  • Uses site soil as the structural mass
  • Flexible — tolerates settlement on weak foundations
  • Inclined units allow a green, vegetated face
  • PVC coated wire for a long buried service life

Questions

Common questions

What are facia units for?

They form the visible face of a reinforced soil wall or steep slope. The unit is a mesh panel with a tail that extends back into the compacted fill, so the face is tied into the reinforced mass rather than merely leaning against it.

What face angles are available?

Vertical, and inclined from roughly 45° to 87°. The angle is chosen with the design — steeper faces save land take, flatter faces reduce the reinforcement demand. Send the cross-section and we will confirm what the drawing needs.

Are facia units coated?

They are normally supplied PVC coated over galvanized wire, because the face of a reinforced soil structure is permanent, exposed and expensive to intervene in later.
