Selection of effective erosion control materials involves matching appropriate solutions to specific site problems. Factors to be considered include the steepness of slopes, the amount of water flow, and the budget. Different materials are necessary for surface protection, slope stabilization, and drainage control. There is a great variety in cost and life of these materials. Proper choice of materials is essential to avoid costly failures.

Surface Protection

  • Organic mulch: Apply 5-8cm wood chips or straw layers
  • Reduces raindrop impact erosion by 95%
  • Lasts 6-12 months before replenishment needed
  • Cost: $30-60 per cubic yard

Slope Stabilization

  • Biodegradable geotextiles: Coconut or jute mats
  • Provide immediate 75% erosion control
  • Degrade naturally over 2-5 years
  • Cost: $1-3 per square meter installed

Extreme Conditions

  • Gabion baskets: Stone-filled wire containers
  • Handle slopes exceeding 40% gradient
  • Last 25+ years with minimal maintenance
  • Cost: $15-25 per linear meter

To achieve the best results, combine materials. Place geotextile mats underneath organic mulch for both instant and future protection. At the base of slopes, place coconut rolls with riprap stone on top. The effectiveness of these combinations is improved by 30% with a reduction of costs due to the synergy of materials.

Select the materials according to the level of water flow. In low-flow areas, straw mulch or wood chips are needed. In medium-flow channels, use coir logs or gravel filters. In high-velocity flows, *gabion baskets* or *concrete revetments* are necessary. Peak stormwater volumes must always be considered.

The quality of the installation determines how long the material can be used. Before installing the geotextile, prepare the soil surfaces. Properly anchor materials at the tops and bottoms of slopes, and overlap rolls by 15cm at the edges. Compact stone bases to their fullest. If you install the materials correctly and sensibly, you will double their life expectancy.

Maintain materials seasonally. Inspect after storms exceeding 50mm of rainfall. Replenish mulch washed from slopes. Replace degraded sections of biodegradable products. Clear debris blocking drainage paths. Regular upkeep maintains 90%+ effectiveness.
