PHYSICAL PROPERTIES
Concrete Erosion Control Mats are supplied in rolls for ease of handling and efficient installation.
- Roll size options: 2.4m wide x 6–15m lengths (other widths available)
- Approximate mat weight: 45–50kg per m² (depending on configuration)
- Individual concrete block size: 160 x 148 x 58mm
- Spacing between blocks: 40mm
- Standard underlay: 200gsm non-woven geotextile
Optional underlay options (on request):
- 400gsm non-woven geotextile underlay
- Biodegradable nutritional geotextile underlay
WHAT IS IT?
Concrete Erosion Control Mats are a cast concrete block system embedded into a high-strength biaxial geogrid, supplied with a geotextile underlay attached to the underside. The mats are designed to provide long-term erosion protection while maintaining the ability to conform to ground contours during installation.
The system is available in two flexibility configurations, allowing selection based on ground conditions, hydraulic forces, and required surface stiffness.
CHARACTERISTICS
- Supplied in roll form for rapid deployment
- Conforms to natural ground profiles, slopes, and channels
- Available with greater or lesser flexibility, depending on configuration
- Open block spacing allows controlled water filtration and sediment capture
- Suitable for vegetated and non-vegetated applications
- Underlay protects the subgrade and assists in erosion control
PERFORMANCE DATA
- Expected design life: 50+ years (non-vegetative), 100+ years (vegetative)
- Ultimate tensile strength: 80 kN/m
- Critical flow shear stress (initial scour): 1.149 kPa
- Maximum flow velocity: 5.79 m/sec
- Percentage open area: 20%
- Manning’s n: 0.05
