Gabion Green Terramesh With Long-Term Erosion Controlling And Plant
Gabion Green Terramesh is an environmental friendly gabion type used for erosion control
for rivers, shorelines and stream banks. They provide immediate and
long-term erosion control and create hospitable conditions for
Gabion Green Terramesh helps to slow water velocities near the banks and trap sediment.
They are made of PVC coated wire mesh baskets with an inclined face
of 45 or 60, lined with a coconut fiber blanket on the facing and
filled with a mix of stone and topsoil. The 1000 gr/m2 heavy
coconut mat has a durability of 3 to 5 years that allows vegetation
The integration of the vegetation provides a high resistance and
durability of the structure. As the root system develops, it
reinforces the soil providing a significant resistance to the
Live staking and brush layering are two soil bioengineering
techniques frequently use with Green Terramesh to enhance the vegetation.
Green Terramesh units are supplied in the collapsed form, folded and bundled. The
bundles are compressed, strapped together and wrapped with plastic
at the factory for easy shipping and handling. Each bundle is
labeled with a tag reporting the sizes of the units contained.
Lacing wire is supplied in coils.
The folded units shall be taken out from the bundle and placed on a
hard flat surface. Green Terramesh units shall be opened, unfolded and pressed out to their original
shape. When the units are unfolded for assembly, they will have one
or two shipping folds. They can be removed by placing the fold over
a board and walking along the sides.
When using lacing wire, cut off a piece of wire approximately 1,5
times the length of the edge to be tied. The maximum length of the
edge to be tied at one time shall not exceed 1 m. Longer edges
shall be joined by several lengths of wire. Lacing wires shall be
secured around the selvedge wire or heavier edge wire, where
present, by looping and twisting the lacing wire around itself.
Proceed tying with alternate double and single loops. Double loops
shall be made at intervals not greater than 300 mm. All panels
shall be pulled tightly together during the tying operation. Pliers
may be used to create tight joints. The other end of the lacing
wire shall be secured by again looping and twisting the wire around
itself. When using lacing wire to assemble the units, you should be
taken to avoid damaging the wire coating. When steel ring fasteners
are used, the custom made We Manual Spenax Tool is required and
available for hire. Rings shall be installed at the top and the
bottom connections of the end and centre diaphragms and then a
maximum spacing of 100 mm along all edges shall be used.to Connect
with ring fasteners between adjacent units. Connections made along
the panel edges assure a flat surface for fill placement.
The foundation on which the Green Terra mesh units are to be placed shall be level and graded to the elevations
as shown on the project construction drawings, and free of surface
irregularities, loose material and vegetation in accordance with
the project specifications.
