Terramesh & Green Terramesh
Terramesh is a versatile, modular system for reinforced slope
systems and mechanically stabilised earth walls that can be a more
cost effective solution than the mass gravity Gabion wall because
of the speed of installation and reduced rock fill requirements.
For mechanically stabilised earth slopes and embankments that
require vegetation, the front face of Green Terramesh can be filled
with soil and planted, creating a green slope.
Terramesh retaining wall system is designed for use in a wide range
of applications in road, mining and rail infrastructure works. It
comprises of a gabion type facing with integral woven mesh soil
reinforcement panels that can be used to construct structures with
either a stepped front face or vertical facing.
Terramesh are pre-assembled units of double twisted wire mesh. The
facing section of the unit is formed by connecting a back panel and
diaphragms to the main fascia unit, thus creating the rectangular
shaped cells used for stone confinement. The geogrid reinforcement,
fascia and lid are all one continuous panel of mesh. Terramesh
System units are supplied in standard lengths, requiring no cuts on
They can be used individually or combined with geogrid
reinforcement for the stabilisation of soil slopes in a wide range
of applications including slip repair work, steep slope
construction in both residential and road infrastructure works as
well as in specialist applications such as noise barriers and
Green Terramesh soil reinforced slope structures can exceed 50m in
height and can be used in a wide range of engineered soil types.
Green Terramesh structures allow for geogrid to be terminated at
the face minimising the risk of exposure of the geogrid to UV, fire
or vandalism. Both the Terramesh and Green Terramesh systems have
independent technical approval.
Green Terramesh units provide a permanent formwork in the front
face of reinforced soil slopes as well as contributing to the
overall stability of the structure. The front face is normally soil
filled and planted to achieve vegetated solution however where
required rock can be used in the front face. This versatility along
with the construction and technical advantages offered by Green
Terramesh have seen the widespread use of this system throughout
Australia and New Zealand.
The fixed face angle and vertical lift simplifies construction of
the reinforced soil slope.
When combined with geogrid, Terramesh and Green Terramesh
structures can exceed 50 m in height.
Terramesh features a Galmac coated wire mesh, protected by a
polymeric barrier made of PVC. This improves corrosion resistance
and enhances the system’s durability.
Terramesh has a permeable front face to allow drainage of the
It is structurally safe in the face of fire and reduces
environmental impacts by incorporating vegetation on the front
Terramesh is quick to install and tests have proven its durability
and strong performance in coastal applications.
Green Terramesh can be used in a wide range of engineered soil
types Green Terramesh structures allow for geogrid to be terminated
at the face minimising the risk of exposure of the geogrid to UV,
fire or vandalism
The Green Terramesh system has independent technical approval.
To support design of retaining walls, slopes, embankments,
hydraulic structures and rockfall protection we offer an advanced
suite of software free to our clients.
To assist engineers with the design process, our engineering
specialists are available to give technical advice in the use of
the software as well as provide training in-house or via seminars.
Our team can also provide certified design if required.
Terramesh and Green Terramesh units used individually or with
geogrid in reinforced soil slope construction. The backfill used
with Terramesh is generally an engineered fill suitable for use on
most earthworks sites. A maximum particle size of 75 mm is
recommended to limit installation damage to the mesh coating and
geogrid reinforcement. A 300 mm to 500 mm zone of topsoil is placed
up against the geotextile in the front face to provide a growing
medium for the selected vegetation. Rock can be used in place of
topsoil to line the face in areas subject hydraulic action or where
a rock feature is required. bidim geotextile is used at the
interface between the gabion rock and backfill.
Gabion mattress is made of double twisted hexagonal wire mesh. It
is of great significance in river bank protection and can be used
for permanent erosion control in channels, stream banks, spillways
and stable slopes from surficial erosion. The stone confinement
within the units allows for higher shear stress resistance than the
riprap. Our company can provide you with quality gabion mattress of
The base is divided into compartments and filled with stones at the
project site. With lids closed, Gabion Mattresses form flexible,
permeable, monolithic structures. The 100 feet (30m) long units
make its installation fast and economical. Soil bioengineering
techniques can be used to promote vegetation in the gabion mattress
to provide enhanced shear resistance.
Characteristics of Gabion Mattress:
* Control and guide of water or flood
* Flood bank or guiding bank
* Preventing of rock breaking
* Water and soil protection
* Bridge protection
* Strengthening structure of soil
* Protection engineering of seaside area
Applications of Gabion Mattress:
Gabion mattress plays an important part in preventing natural scour
of water and retaining earth. It is mainly applied for river bank
protection as well as foreshore and side slope protection.
Meanwhile, it provides protection on water courses and coastal
revetments against scour and erosion.
