Troughout the Bank Stabilization Program of Hydro-Québec, more than 55 km of riverbanks of the Outaouais River have been protected with natural granular fill material.

Poly-Géo was involved at all stages of the desk study as well as the field work, which took place between 1990 and 1998. Today, vegetation has grown and developed on most of the reservoir banks which brings back the natural character of the area. This program has been qualified as a complete success by government authorities.

Poly-Géo was involved in all aspects of the project :

• bank dynamics (erosion-sedimentation) study;
  
• environmental impact assessment study;
  
• stabilization design;
  
• fiel work planning as well as specification and design documents;
  
• construction material identification;
  
• work supervision;
  
• follow up.
