The bio engineering uses life or dead plants (or a portion of them) as well as other dead material (e.g., stones, tree trunk, wood, geotextile) to solve engineering issues: erosion control, soil stabilization and restoration. Therefore, the bio engineering can be defined as a toolkit with lo environmental impact, used to contemporarily improve the soil and the environment.

IRIDRA's projects adopt bio engineering everytime is needed a slope or soil stabilization, despite particular conditions requesting conventional engineering solutions

Advantages 

• creation and/or restoration or natural or semi-natural areas
  
• soil consolidation and/or soil covering
  
• reduction of bank erosion
  
• protection to soil erosion
  
• hydrological advantages in terms of the rainfall infiltration
  
• improved drainage
  
• landscaping
  
• lower CAPEX and OPEX in comparison to conventional engineering solutions
