What is EROSION CONTROL SHEET?
A new method of revetment covered
with plants to protect against erosion by reinforcing
the erosion resistance of plants
RivergreenTM is a new
method of revetment work for erosion protection by reinforcing
erosion-proof ability of plants. It was developed through
a collaborative project by AGT and the River Lab.of Ministry
of Land, Infrastructure and Transport,whose title is“Studies
on sheet material which is able to control erosion and
luxuriance of plants".
The sheet is leachy and has air
gaps bigger than soil grain. It can reduce the eroding
force towards the ground.(current speed) To less than
critical upset ratio to corrosion.

Research Report on Development of Erosion-proof Sheet
Using Erosion-proof Capability of Plants".

Features of RIVERGREEN ™
RivergreenTM forms the
crossings of polypropylene fiber which has capsule and
core structure into three-dimensional structure with heat-sealing.
It can maintain high porosity and strength without using
binder such as adhesive.
- Outstanding erosion-proof capability
The sheet is entirely heat-sealed, which makes the crossings
of fiber bonded evenly with adequate strength, and also
it has very high compression recovery properties. Therefore
it makes even three dimensional net keeping high erosion
- Outstanding strength and workability
The sheet has flexibility, so there is no deformation
or damages to decrease the high erosion resistance.
It is easy to bond and repair the sheets by heat-sealing
- Outstanding soil-filling capacity
With high porosity of soil filling can be performed
efficiently and appropriately regardless of dry type
or wet type.
- Burning resistance
Even when a fire breaks out on the sheet, the sheet
would not catch fire nor the fire spread out.
BONDING RIVERGREEN™ AT SITE
|1.Bonding by butt sealing
One of the features of RIVERGREENTM is
heat-sealing can be performed at site with heated
air. The bonded section is as strong as the rest of
the sheet. Thus, material loss can be decreased significantly
compared with overlapping method.
2.Bonding by overlapping
