Wood Wool Erosion Control Blanket (Type 3B)

Premium Poplar Wood Wool (Excelsior) Erosion Control Blanket for Long-Term Slope Stabilisation

EnviroWool SoilLock™ is a Type 3B wood wool erosion control blanket manufactured from premium Populus canescens (poplar) excelsior for long-term slope stabilisation in South Africa.

Geosynthetics Africa proudly introduces EnviroWool SoilLock™, a high-performance Type 3B wood wool erosion control blanket manufactured from sustainably sourced Populus canescens (Poplar tree) wood wool.

Designed for demanding erosion control applications, EnviroWool SoilLock™ delivers superior soil retention, moisture conservation, vegetation establishment, and slope stabilisation across civil, mining, and environmental rehabilitation projects throughout Africa.

Why EnviroWool SoilLock™ Dominates

✔ Premium Poplar Wood Wool (Excelsior)
✔ Type 3B Performance Classification
✔ Functional Longevity up to 24 Months
✔ High Water Absorption (171%)
✔ C-Factor < 0.05 (Excellent Erosion Reduction)
✔ Biodegradable Stitching
✔ Photodegradable Netting
✔ Ideal for Mining Rehabilitation & Infrastructure Slopes

Product Description

EnviroWool SoilLock™ is manufactured from Poplar wood wool fibres sewn between two lightweight, photodegradable polypropylene nets using biodegradable yarn at 50 mm stitch centres.

The open-matrix excelsior structure creates:

  • Superior soil-to-fibre contact

  • High friction interface

  • Moisture retention zone for seed germination

  • Long-term erosion protection

Unlike coconut fibre mats, wood wool provides a balanced combination of strength, water absorption, and soil reinforcement.

Performance Advantages Over Alternatives

Feature EnviroWool SoilLock™ Coconut Fibre Straw Blankets
Longevity Up to 24 Months 12–24 Months 6–12 Months
Water Absorption 171% Moderate Low
Shear Resistance >100 Pa Moderate Low
C-Factor <0.05 Higher Higher
Structural Integrity High Moderate Low

EnviroWool SoilLock™ provides superior erosion resistance and vegetation establishment compared to straw-based erosion control blankets.

Installation Guidelines

Proper installation is critical to performance.

  1. Prepare subgrade (remove loose debris, grade slope)

  2. Seed and fertilise prior to installation (if required)

  3. Roll blanket downslope

  4. Overlap edges by 100–150 mm

  5. Staple at 300–500 mm centres (increase on steep slopes)

  6. Install anchor trench at crest (300 mm x 300 mm recommended)

  7. Backfill and compact anchor trench

For high-flow channels or slopes >3H:1V, consult Geosynthetics Africa technical team.
