Reinforced HDPE Geocell Cellular Confinement System for Slope Protection
HDPE Geocell Introduction :
It was made of a new type of high-strength geosynthetics, which welding the strengthened HDPE sheets by the high-power ultra-sonic and forming to be a structure of three-dimensional reticular formation.
Easily folding and convenient for transportation. For construction, the geocell can be pull into a network and launched into a three-dimensional honeycomb grid.
As it was filled in soil, macadam, concrete or other granular materials, constituted to be a construction, which has strong sidewise restraint and high rate of stiffness.
HDPE Geocell Production Process:
HDPE Geocell Applications:
¨ Load Support
¨ Slope Protection
¨ Retaining Wall
¨ Channel Protection
¨ Ground Stabilization
¨ Erosion control
HDPE Geocell Advantage:
¨ Virgin HDPE basic with Unique Formula.
¨ Tensile Strength reaches 33000 kN/m² (33 MPa)
¨ Seam Peel Strength above 16 kN/m (USACE GL-86-19); Split Strength above 28 kN/m (EN ISO13426-1 Method C).
¨ Various weld spacing available from 220mm to 1600mm
¨ Various strip height available from 25mm to maximum 300mm
¨ Maximum strip length reaches 8m, expanded width reaches 6m.
¨ Reduce construction thickness, improve load and bearing capacity, long life span, save maintenance cost
¨ Easy to transport, all weather installation with high construction speed.
¨ Local infill materials available, ungraded or recycled materials are acceptable, reduce construction cost.
