3D Geomat for Erosion Control

Product Definition

3D Geomat for erosion control is a three-dimensional synthetic polymer mat designed to stabilize soil surfaces,      protect slopes from water and wind erosion, and promote vegetation growth by forming a permanent reinforcement layer.

Technical Parameters and Specifications

The following specifications represent commonly adopted engineering-grade parameters for 3D Geomat systems:

• Thickness: 10 mm – 20 mm

• Unit weight: 250 g/m² – 500 g/m²

• Material: UV-stabilized polypropylene (PP) or polyethylene (PE)

• Tensile strength: ≥ 1.2 kN/m (MD/TD)

• Elongation at break: ≥ 30%

• Operating temperature range: -40°C to +80°C

• Design service life: ≥ 20 years (soil-buried conditions)

Structure and Material Composition

The performance of 3D Geomat for erosion control is driven by its engineered spatial structure:

• Upper Layer: Randomly oriented polymer filaments forming surface protection

• Middle Layer: Interlocked three-dimensional mesh providing soil anchorage

• Bottom Layer: Open structure enabling root penetration and water infiltration

• Material Additives: UV inhibitors, anti-aging stabilizers

Manufacturing Process

The production of 3D Geomat for erosion control follows controlled industrial processes:

1. Polymer raw material selection and blending with stabilizers

2. Extrusion of continuous filaments using multi-nozzle extrusion equipment

3. Random laying and spatial bonding to form 3D structure

4. Thermal welding or calendaring for dimensional stability

5. Online thickness and weight inspection

6. Roll cutting, packaging, and batch traceability labeling

Industry Comparison

Application Scenarios

3D Geomat for erosion control is widely adopted by:

• Highway and railway slope protection projects

• Hydraulic engineering and riverbank stabilization

• Mining rehabilitation and landfill capping

• Municipal landscaping and green infrastructure

• Industrial parks and EPC earthwork projects

Core Pain Points and Solutions

• Pain Point: Soil loss on steep slopes
  Solution: 3D structure provides mechanical anchorage

• Pain Point: Poor vegetation survival
  Solution: Open matrix retains moisture and seeds

• Pain Point: UV degradation of materials
  Solution: UV-stabilized polymers

• Pain Point: High maintenance costs
  Solution: Long service life with minimal intervention

Risk Warnings and Mitigation

Potential risks and corresponding mitigation measures include:

• Improper anchoring: use specified steel or polymer anchors

• Inadequate overlap: maintain ≥100 mm overlap between rolls

• Exposure before backfilling: limit UV exposure during installation

• Incorrect slope preparation: ensure compacted and graded subgrade

Procurement and Selection Guide

1. Define slope gradient and hydraulic conditions

2. Select appropriate thickness and unit weight

3. Verify polymer type and UV resistance

4. Check compliance with project specifications

5. Request laboratory test reports

6. Evaluate supplier manufacturing capability

7. Confirm logistics and roll dimensions

Engineering Case Study

In a highway slope stabilization project, 3D Geomat for erosion control with 15 mm thickness was installed      on a 35° embankment slope. After hydroseeding and six months of growth, vegetation coverage exceeded 90%,      with no visible soil erosion during seasonal rainfall.
