Bio geocomposite
Would you like to to learn more about our solutions?
The PolGrid Bio biogeocomposite is a combination of a geogrid with stiff nodes and a biotextile with grass seeds. It is practical and convenient method of turfing, greening, but also for securing slopes near roads and highways, railway embankments, flood embankments and industrial areas. It allows to quickly cover and protect the soil surface of the slope, protecting it against erosion and near-surface landslides.
Intended use:
- Roads and highways – for securing inclined areas and greening all adjacent areas.
- Railway embankments – to protect against erosion, landslides, leaching and blowing.
- Dunes – to protect against erosion, landslides, leaching and blowing.
- Slopes – to protect against erosion, landslides, leaching and blowing.
- Flood embankments – to protect against landslides, leaching and blowing.
- Sports grounds – for creating boards and covering of sports grounds.
PolGrid Bio is a highly efficient solution for soil strengthening and reinforcement. Depending on the project requirements, the appropriate type of the geogrid reinforcing the biotextile is selected.
