Description
DKM- PCA Geocell
It’s a lightweight and flexible three-dimensional structure ,expandable panels made of Polymeric Composite Alloy materials which are ultrasonically bonded sheets together to make to be an extremely strong configuration.The PCA geocell sheet with a much higher tensile strength and welding peel strength, also with a excellent performance of Dynamic Mechanical Analysis (DMA) . It mainly applied in:Irrigation Ditch,river,Channel, Slope&Green wall protection, Soil stabilization Load support for access way,air port, parking lot,etc.
FEATURES AND BENEFITS:
- Light weight, wear-resistant, chemical stability, anti-aging,anti-ultraviolet, anti-acid/alkali corrosion.
- Wide temperature rangeadaptable, high tensile strength.
- good rigidity and toughness, good load capacity and anti-erosion ability.
- Size is variable, change the height and welding distance can meet the needs of different projects.
- Retractile, easy to transport.
APPLICATION:
- Toreinforce theroadbed of highway/railway.
- To bear the pressureof dam, retaining wall.
- To protect slope from landslide and mudslide.
- To protect channel from water flowing.
- To be used as independent wall, wharf and breakwater, etc.
