Geocell for Slope Protection

Product Definition

Geocell for Slope Protection is a three-dimensional cellular confinement system manufactured from high-density polyethylene, designed to stabilize slopes, prevent erosion, and improve load distribution by confining infill materials within interconnected cells under civil and geotechnical engineering conditions.

Technical Parameters and Specifications

The following parameters are commonly adopted in engineering design and procurement of Geocell for Slope Protection:

• Raw Material: High-density polyethylene (HDPE)

• Cell Height: 50 mm / 75 mm / 100 mm / 150 mm / 200 mm

• Cell Size (Expanded): 210 × 210 mm or 250 × 250 mm

• Sheet Thickness: 1.1 mm – 1.8 mm

• Weld Peel Strength: ≥ 1000 N/100 mm

• Tensile Strength: ≥ 20 MPa

• Carbon Black Content: 1.5% – 2.5%

• Operating Temperature: -40°C to +80°C

• Design Service Life: ≥ 40 years under normal exposure

Structure and Material Composition

Geocell for Slope Protection adopts a honeycomb-like cellular structure formed by ultrasonic or thermal welding:

• HDPE Strips: Provide flexibility, tensile strength, and chemical resistance

• Welded Joints: Ensure structural integrity under shear and tensile stress

• Perforated or Smooth Walls: Optional for drainage and vegetation integration

• Three-Dimensional Cells: Confine soil, gravel, or concrete infill

Manufacturing Process

The production of Geocell for Slope Protection follows a standardized industrial workflow:

1. Resin Preparation: HDPE resin mixed with stabilizers and carbon black

2. Sheet Extrusion: Flat extrusion lines produce uniform HDPE sheets

3. Strip Cutting: Sheets cut into precise-width strips

4. Welding: Ultrasonic or hot welding forms cellular joints

5. Perforation: Optional punching for drainage and root penetration

6. Expansion Testing: Verifies dimensional stability

7. Inspection and Packing: Mechanical tests and compact folding for transport

Industry Comparison

Application Scenarios

Geocell for Slope Protection is widely specified by EPC contractors, distributors, and engineering consultants for:

• Highway and railway embankment slopes

• Riverbank and canal slope stabilization

• Landfill side slopes and capping systems

• Mining waste dumps and haul road slopes

• Retaining structure backslopes

• Green slope protection with vegetation infill

Core Pain Points and Engineering Solutions

• Slope Erosion: Cellular confinement reduces soil displacement under rainfall

• Shear Failure: Improved load distribution limits downslope movement

• Vegetation Loss: Cells protect root systems and retain moisture

• High Maintenance Costs: Durable HDPE structure minimizes long-term repairs

Risk Warnings and Mitigation Measures

• Ensure proper anchoring to prevent sliding on steep slopes

• Avoid low-quality welds that reduce tensile performance

• Select UV-stabilized material for exposed environments

• Use appropriate infill material to match slope gradient

Procurement and Selection Guide

1. Define slope angle, height, and soil conditions

2. Select cell height based on erosion intensity

3. Determine perforated or non-perforated configuration

4. Verify mechanical and weld strength test reports

5. Confirm compatibility with infill material

6. Assess installation guidance and technical support availability

Engineering Case Study

In a highway expansion project, Geocell for Slope Protection with 150 mm cell height was installed on a 1:1.5 embankment slope. The cells were anchored at the crest, infilled with topsoil, and hydroseeded. After three monsoon seasons, no visible erosion or slope failure occurred, confirming long-term stability.
