Geobuildex Erosion Control MAT (ECM)
Environmentally conscious engineers, architects and designers are choosing natural fibres and methods to meet the challenges of erosion of cut slopes, wetland rehabilitation, river bank and creek erosion to name a few. To achieve natural growth regeneration or reclamation under extreme conditions, grass seeds and young plants need to be protected while vegetation establishes.
Geobuildex Erosion Control Mat (ECM) meets these challenges wherever rapid germination and sustained growth is required to solve erosion control and landscaping problems. One of the best way is still the nature’s way to heal erosion through the establishment of living matter and organisms.
Not all soil surface erosion is the same. When planning erosion prevention and remediation measures, soil type, climate and weather, moisture availability and humidity, the length and degree of slopes are some factors that need to be considered.
WHAT IS GEOBUILDES ECM?
Geobuildex ECM consists of natural materials-biodegradable coir, palm or straw fibres, stitched together with lightweight reinforcing polymer mesh to form a flexible but strong knitted bioengineered mat. The matrix provides a pad for surface movement of runoff, reduce erosion and minimize downward migration of soil beneath the blanket.
Important Highlights
The common objective in using biodegradable mats is to turn the degradation of the natural fibres into soil feeds. However, it must be noted that such degradation should not happen prematurely since the grass roots take even up to a year to get fully entrenched into the soil sufficiently to withstand wash-off.
Geobuildex ECM would greatly protect the seeds and soil from the ravages of the soil particles detachment caused by wind and rain. The protective mulch covered by the blankets creates optimal conditions for seed germination and growth.

Geobuildezx ECM WORKS EFFECTIVELY IN THE FOLLOWING CONDITIONS:
1. Rainfall
It absorbs and dissipates energy released by heavy falling rain and hence minimizes and prevents soil and fertilized seeds of being washed away.
2. Surface Runoff
The three dimension blanket matrix reduces velocity of surface runoff and hence helps to prevent the formation of rills and gullies.
3. Drought Condition
The natural fibre retains moisture and supports vegetation growth during the drought condition.
4. Improved Soil Fetility
Since Geobuildex ECM biodegrades and decomposes with time, it naturally fertilizes the soil by increasing and improving the organic content.
5. Improved Plant Roots System
The interlocking matrix of the coir or palm fibres assists young roots to spread easily across the surface of the slope and penetrate its roots deeper into the soil as the plant becomes established.
6. Cost Effective
Since straw, palm fibres or coir are easily available in abundance locally, these natural fibres are used to produce Geobuildex ECM and made into efficient roll sizes for ease of transporting, handling and installation on site.
THE COMMON APPLICATIONS OF GEOBUILDEX ECM ARE:
- Erosion protection of slopes
- Revegetation of newly cut and fill slopes
- Protection of natural or man-made lakes, wetland, channels, river and waterways.
- Leisure developments namely landscaping of golf course and residential projects, etc.
- Revegetation of reclaimed mining lands.
