3-D Erosion Control Mat
Erosion
Control is one of the essential component in today's slope protection works. Effective
Erosion control prevents landslips in urban/rural areas adjoining habitation/
buildings and truck roads particularly in tropical regions. Likewise, this
measure is equally important in respect of safety and durability of embankment
for river and railway.
The 3-D Erosion Control Mat (3-D ECM) is developed
specifically for these purpose. Permanent erosion protection to slope is formed
with competitive low cost and easy installation when compared with the
traditional concrete/stone paving method. Environmentally speaking, the 3-D ECM
is also superior to shotcreting by upgrading the surrounding aesthetics and
avoid air pollution.
3-D ECM is
made of HDPE filaments fused and crossed together to form a three-dimensional
multilayer mat. It is light and flexible to suit uneven slope profile with
spacious volume of more than 90% for soil filling. These efficiently enhance the
growing of vegetation roots into the soil and integrate with the ECM to give a
secure and interlocked composite erosion control system. The flexibility of the
whole system also prevents the formation of voids when settlement occurs.
Moreover, the 3-D Wavy profile retards the surface water flow and wind erosion
to allow sedimentation.

The 3-D ECM
provide excellent soil retention percentage for slope with different
gradient. Prior to seed germination, proven results demonstrate a 97.5% soil
retention for slope gradient 45°, 84% for slope gradient 60° for
vertical slope. The 3-D structure is far more efficient than ordinary 2-D mat. |

Wind and
rain erosion to slope are mitigated prior to seed germination. Conventional
biodegradable protection mat only serves for temporary purpose which lasts
less than half year. |

Minimize
the seed loss by nature and maintain an even spread on slope. |

|
The
vegetation, 3-D ECM and soil integrate into a robust interlocked structure
which can resist high water and tidal erosion. |

|
The
3-D wavy profile of 3-D ECM enhances the formation of numerous small turbulent
by wind/ water which in return dissipates excessive and retains sediments. |

Rapid
growing of landscaping / Hydroseeding on 3-D ECM are both aesthetically
friendly and improve environmental protection. |
