Gabions and rock mattresses are baskets or cages manufactured from heavily galvanized wire and also with the addition of a PVC sleeve coating on the core wire filled with mattress rock.
Applications include:
- Retaining walls
- Weirs and drop structures
- Culvert protection
- Bridge abutment protection
- Channel lining
- Chutes and spillways
- River crossings
- Landscaping
- Rockfall protection netting (mesh)
- Erosion control and stabilisation
Gabion and rock mattress structures are porous to prevent build up of hydrostatic pressure and are able to withstand differential settlement.
