Maccaferri Terramesh is defined as PVC coated heavily galvanized steel wire mesh box-shaped basket with a section of the mesh extending into the soil to act as soil reinforcement into the backfill soil. The basket is filled on site with clean-hard stones.
The selvedges of the Terramesh are the thicker perimeter and edge wires to which the wire mesh is securely tied to withstand sudden or gradual stress from any direction.
The diaphragms are the internal wire mesh partitions which divide the Terramesh box into equal sized cells.
Lacing and bracing wire is the wire used to assemble and join the Terramesh units.
Connecting wires are the internal wires used to prevent the Terramesh from bulging.
The advantage of terramesh :
- Permeability of the front face, guaranteeing drainage of the backfill
- Flexibility , enabling the structure to take up ground settlement without compromising structural integrity
- Ease of construction
- Significant soundproofing characteristics (18-28 decibel)
- Structural safety in case of fire near the front face
