3D geomat

Key Features

1. Slope Stabilization

• Erosion Control: Reduces soil loss by 85-95% under 50mm/hr rainfall

• Load Distribution: Enhances slope stability (FOS improvement from 1.2 to 1.8)

2. Vegetation Support

• Root Anchorage: 3D structure allows 2-3x deeper root penetration vs. bare soil

• Moisture Retention: Holds 15-25L/m² of water for plant establishment

3. Material Properties

• Tensile Strength: 8-15kN/m (ASTM D4595)

• UV Resistance: ≤5% strength loss after 2000 hrs exposure

• Degradability: Bio-based options available (2-5 year degradation cycle)

Technical Specifications

Installation Process

1. Site Preparation

• Clear debris and grade slope to ≤1:1.5 (V:H)

• Apply starter fertilizer (NPK 10-10-10 @ 50g/m²)

2. Mat Deployment

• Unroll top-to-bottom with 5% overlap

• Secure with 12-16 staples/m² (minimum 500N pullout resistance)

3. Vegetation Establishment

• Hydroseeding: Apply 80g/m² seed mix (grass:legume:shrub = 3:1:1)

• Initial Maintenance: 20L/m²/week irrigation for 60 days

Performance Data
