ROCK FALL PROTECTION

LIFE EXPECTANCY OF CLASS III GALVANIZED GABIONS

A GENERAL NOTE ON GALVANIZING:

GALVANIZING PROTECTS THE STEEL GABION WIRE FROM OXIDATION BY FORMING A PROTECTIVE COATING THAT PROLONGS THE LIFE EXPECTANCY OF GABIONS. IT ALSO ACTS AS A SACRIFICIAL ANODE THAT PROTECTS AGAINST RUST EVEN IF THE COATING IS SCRATCHED EXPOSING THE BARE STEEL

100+ YEARS -  DESERT, LOW HUMIDITY, DRY RURAL AREAS AND INSIDE BUILDINGS

50+ YEARS - URBAN AREAS WITH LOW HUMIDITY, MODERATE POLLUTION AND FRESH WATER COASTAL AREAS

30+ YEARS - INDUSTRIAL AND COASTAL AREAS WITH 1 MILE DISTANCE FROM OCEAN

15+ YEARS - AREAS OF HIGH HUMIDITY, INDUSTRIAL AND COASTAL AREAS WITHIN 500 YDS OF OCEAN

5 YEARS - AREAS OF EXTREME HUMIDITY, HIGH POLLUTION INDUSTRIAL AND COASTAL WITH CONTACT WITH OCEAN SALT WATER

 

NOTES:

  • GOOD DRAINAGE BEHIND AND BELOW A GABION WALL WILL HELP TO IMPROVE THE STABILITY OF A RETAINING WALL AND  PROLONG ITS LIFE
  • GALVANIZED AND PVC COATED GABIONS WILL NORMALLY DOUBLE A GABION'S LIFE EXPECTANCY
  •  GABION LIFE EXPECTANCY WILL BE INCREASED IN AREAS OF ACID OR ALKALINE SOIL CONDITIONS BY USE OF GEOTEXTILE FABRIC PLACED BETWEEN THE BACK FILL SOIL AND THE RETAINING WALL GABIONS
  • PVC COATED WIRES PERFORM BETTER THAN BASIC GALVANIZING AND WILL USUALLY DOUBLE THE LIFE EXPECTANCY OF A GABION INSTALLATION
