Geonets and Gabion

 
Enquiry
   
 
Tuflex Geonets are high strength polymer grids with integrally fused joints having high dimensional stability and junction strength.Manufactured from high-density polyethylene (HPDE), Geonets are also protected against environmental and ultra-violet degradation.
 
Slope Erosion Control
Geonets 131 along with Non-woven Geotextile are ideally suited for erosion control of slopes. These are installed on the surface of slope along with top soil for vegetation growth, which will
Prevent erosion of soil by retarding the velocity of water run-off on slope with its three dimensional profile
Promote water percolation in soil as well for growth of natural vegetation
Once vegetation is established on the slope surface, the girds act as permanent reinforcing medium for grass roots
This helps in generation of dense grass cover by preventing the roots from washout even in adverse weather conditions
 
Gabions for Coastal Erosion Control or Waterfront Protection
In case of heavy erosion and scouring which takes place in sea coasts/river banks due to extensive wave action, it is essential to break up the waves and control erosion. Gabion application helps in
Break up and absorption of wave energy
This leads to process of silting and consequently offers permanent solution to the erosion problem
Gabions and Mattresses for waterfront protection are easily constructed at site in various sizes by fabricating a box like structure from the Geogrid roll (ready made netting) with jointing being done with polymer ropes. The box structure is filled with stones and the topflap closed and braided.
Application
 
Road and Railway Embankments
Rock slopes and cliff faces
River and canal bank protection
Sea walls and breakwaters
River bank protection
Waterway control structures
Advantages
 
Gabion construction does not require heavy plant or machinery
Gabion walls can be constructed on filled up compacted soil/rock fill having low bearing capacity and structured may be added later on
Construction of gabion retaining walls does not require cement and sand also curing time
Local labour can quickly trained to construct high quality structures
Construction makes use of low cost locally available stone/boulders quickly
Rapid construction makes them ideal for emergency relief works
Being a flexible structures, Gabion retaining wall can easily adjust to the unequal settlement
