General

Thanks to pre-assembly in the factory, TERRAMESH system solutions offer a range of benefits in comparison to other reinforced earth construction methods:

Easy handling on site: The elements are supplied with the required type of facing and are folded and placed flat onto pallets for delivery. On site, they can be carried manually to the installation location and easily positioned.
Quick installation of the system: At the installation location, the elements are unfolded and the pre-assembled facing is folded up. The pre-assembled inclination triangles act as a construction aid so that the facing can be easily set at the correct angle. Neighbouring elements are clamped together at the horizontal and vertical joints to create a strong form-fit bond.
Extremely reliable handling on site: Because the parts are pre-assembled, there is no need for manual jointing or cutting of the individual components on site. Assembly errors on site are practically ruled out thanks to the simple folding technique used for the pre-assembled elements and the easy attachment of the bracing hooks in accordance with the installation instructions.

There are four different TERRAMESH systems:

GREEN TERRAMESH – the steep slope reinforcement system that is suitable for planting: The system is installed using the wrap-around principle. The steel wire mesh encases the layer of soil laid on top of it. For inclinations up to 70°.

MINERAL TERRAMESH 5×5 – the reinforcement system with a stone backfill behind the front. For inclinations up to 85°.

TERRAMESH DUO – the system solution that has fold-up facing elements on both sides and is laid in layers to create a wall. For inclinations up to 80°.

Because the system is pre-assembled, rapid progress is made on site, even with minimal deployment of personnel and machinery. The reduction in construction time is reflected not only in the costs, but above all in the reduced impact on people and nature. Furthermore, the elements are so easy to handle that they can be installed easily and cost-effectively even in locations where access is difficult.

GREEN

GREEN TERRAMESH – the steep slope reinforcement system that is suitable for planting

GREEN TERRAMESH is a prefabricated modular system made of hexagonal double-twisted wire mesh with duplex protection. The system components comprise a wire mesh with a welded steel grid mat as permanent formwork, pre-bent inclination triangles made of round steel, bracing hooks made of round steel, and an erosion control mat. All essential components are pre-assembled in the factory and can be simply positioned on site, fixed in place and then filled with layers of suitable soil.

Product versions

Two different types of erosion control mat are available as standard:

The EARTH version has an erosion control mat made of brownish-coloured, glass fibre fabric.
The WATER version features a rot-proof, synthetic, non-woven mat.

In order to provide the most cost-effective solution possible, two types of steel wire mesh are available, with different tensile strengths:

The short-term tensile strength is at least 35 kN/m in the case of the LIGHT version and
at least 50 kN/m in the case of the REINFORCED version.

Greening

For the planting, the space behind the permanent formwork of the facing must be filled with vegetative soil. For example, a gravel lawn mix 0/22 pre-mixed with seed that can grow in low-nutrient habitats would be suitable here.

All GREEN TERRAMESH systems can be used for a wide range of support structures with a slope face suitable for planting and a resulting inclination of up to 70°. A stepped structure with berms can be constructed to create whatever inclination is required.

MINERAL

MINERAL TERRAMESH 5x5 – steep slope reinforcement system with stone facing

Like the MINERAL TERRAMESH , the GREEN TERRAMESH system comes ready assembled and its main components also include a double twisted steel mesh with duplex protection, galvanised steel gabion mats (mesh size 5 x 5 cm) as permanent formwork, inclination triangles, and bracing hooks.

In contrast to the GREEN TERRAMESH , however, the MINERAL TERRAMESH does not require an erosion control net on the front face, since the coarse stone fill material (grain size > 80 mm) and the durable steel wire mesh protect the facing against erosion.

Product versions

In order to provide the most cost-effective solution possible, two types of steel wire mesh are available, with different tensile strengths:

The short-term tensile strength is at least 35 kN/m in the case of the LIGHT version and
at least 50 kN/m in the case of the REINFORCED version.

Stone fill

As with the GREEN TERRAMESH , the space behind the facing needs to be filled with a different material. To achieve a gabion look, frost-resistant facing stone with a minimum grain size of 80 mm is used, with a non-woven filter fabric (such as BONTEC NW 26) behind it to hold back fine particles and prevent clogging.

All MINERAL TERRAMESH systems can be used for a wide range of support structures with a gabion appearance and a resulting inclination of up to 85°. A stepped structure with berms can be constructed to create whatever inclination is required.

TERRAMESH DUO

TERRAMESH DUO – the versatile protection wall system

Like the GREEN TERRAMESH, the TERRAMESH DUO system comes ready assembled and its main components also include a double twisted steel mesh with duplex protection, welded steel grid mats with inclination triangles and bracing hooks as permanent formwork, and an erosion control fabric.

The TERRAMESH DUO , however, has fold-up facing elements, at inclinations of 60°, 70° or 80°, on both sides. The individual elements are dimensioned such that they create a prismatic wall structure when installed in layers.

As a wall to protect against rock falls, debris flows, avalanches and mudflows, TERRAMESH DUO is particularly reliable. Due to its capacity to absorb energy, the TERRAMESH DUO system even offers effective protection against multiple, very heavy impacts without sustaining any structural damage.

As a noise protection wall, TERRAMESH DUO ensures excellent noise reduction thanks to its earth-filled structure and full-surface greening. In contrast to conventional noise protection walls, TERRAMESH DUO has a comparatively smaller contact surface, while still ensuring a natural and attractive appearance. As a noise protection structure, TERAMESH DUO is allocated in accordance with DIN-EN 1793 to the classification A3/B3.

As with the other TERRAMESH systems, TERRAMESH DUO protection walls are easy and cost-effective to install. Even high walls can be constructed with structural stability using this system.

Installation

Placement of the elements: The elements delivered flat are positioned on the prepared, compacted and load-bearing subgrade. The rear anchoring is folded out and laid down.
Assembly of the element: The front panel is unfolded, stabilised with tilt triangles and fixed with bracing hooks for the desired front tilt.
Connection of the elements: To fix the individual elements together, the wire meshes are connected with C-rings and hand or hydraulic pliers.
Backfilling and compaction: The floor is installed on the reinforcement behind the front and compacted in layers.
Conclusion of the situation: Once the element has reached its full height, the protruding wire mesh is folded over and fixed in place. Further layers are built up in the same way and connected again.

Sustainability

Sustainability is a key issue in the construction industry and is becoming increasingly important. TERRAMESH system solutions make it possible to use resources more efficiently, lower CO₂ emissions in the construction industry and reduce energy consumption.

Environmentally friendly

and EPD certified

Long working life

Thanks to their high quality, TERRAMESH system solutions have a long service life of 120 years.

Saving resources and protecting the environment

GREEN TERRAMESH provides a natural habitat and absorbs CO2 through its vegetation. The use of available soil material reduces the consumption of resources and saves on material transportation during the construction phase.

Positive effects on the environment

With proven sound absorption, TERRAMESH system solutions are also an advantageous solution in terms of noise and sound insulation. In addition the GREEN TERRAMESH variant offers permanent vandalism protection against graffiti sprayers and the saving of recurring renovation costs.
