EROSION CONTROL
Erosion control with geomat and vegetation is a method to stabilize slopes and prevent soil erosion. This process involves placing a biodegradable or synthetic geomat over the slope surface, which helps anchor the soil and reduces the impact of rainwater.
The geomat provides an ideal environment for vegetation to grow, as its structure promotes root penetration and soil retention. Once vegetation is established, the roots further reinforce the slope, enhancing stability and reducing the risk of erosion.
This approach combines mechanical protection with natural reinforcement, making it a sustainable solution for long-term slope stabilization while promoting a greener landscape.
Erosion control can be combined with soil nailing for extra slope reinforcements.

Applications and Benefits
Erosion Control Applications:
Can be implemented to prevent erosion and stabilize slopes on:
- Highway and roadsides.
- Construction sites.
- Mining and quarries.
- Urban landscaping.
- Dams.
- Landslide-prone areas.
Benefits of Erosion Control:
- Stabliise the soil and reduce surface erosion from rainfall or runoff.
- Promotes vegetation growth on slopes and gives aesthetic appeal to give a more natural-looking.
- Stabilise the whole slop to prevent landslides or minor soil slips.
- Helps manage water infiltration and velocity.
- Cost effective due to less engineering requirement.
Erosion Control Sequence
Geomat Installation
Top-down installation is preferred, but bottom-up may be considered depending on the site conditions.
Steel bars are used to secure the surface and top of the geomat, ensuring it conforms to the slope's contours during installation
Additional slope reinforcement by using soil nailing/rock anchor/driven nail may be implemented depending on the overall slope conditions
Vegetation Installation
The vegetation is planted using bean seeds, mixed with planting media, water, and fertilizer. Then, they are put on the geomat surface.
The water used must be clean and pollution-free to avoid hindering plant growth.
Maintenance Period
After installation, the site enters a three-month maintenance phase if the vegetation quantity is large enough.
Vegetation growth is closely monitored during this period.
Replanting may be necessary if some vegetation fails to grow as expected.
