Deutsch (Österreich) Aftercare and refurbishment
After the flood is before the next heavy rainfall event. In addition to precautionary planning and improvement as well as the renovation of affected protective and hydraulic structures, the main task after flood damage is to renovate elementary infrastructure.
Geobuilding materials can be used for the reconstruction of washed-out roads, slipped embankments and for raising dams.

Applications
Road embankment with point-shaped load-bearing elements for base course reinforcement
For the raising of road embankments or the superstructure of soils with very low load-bearing capacity, geo-reinforced soil bodies on point-shaped load-bearing elements are well suited. The high-tensile geogrids support the arch formation between the pile heads and serve as a load transfer mattress. At the same time, fabric hoses can be used to encase the columns.

Erosion control
Slopes that have eroded as a result of heavy rainfall can be protected and made more resistant to future heavy rainfall events during reconstruction by the additional use of erosion protection products such as crimp mats, natural fibre mats or steel wire mesh up to the duration of full-surface greening.
Slope stabilisation with reinforced earth systems
In the event of extensive erosion or landslides, structural slope stabilisation such as reinforced earth systems are a practical and green solution. With them, practically any original slope can be reproduced using berm backfill. Prefabricated, steel wire-based reinforced earth systems are suitable for fast construction times, confined construction sites and flexible construction material management. With a service life of up to 120 years, various front designs and a very high level of robustness, they can also be used directly near bodies of water to stabilise the banks of torrents.
Products for flood protection
BETEX NW Non-woven Fabrics
The mechanically bonded and thermally post-treated BETEX NW nonwovens in geotextile robustness classes GRK 3 to 5 are made from high-quality polypropylene staple fibres (PP). The high demands placed on geotextile separation, filter and protection layers in civil engineering and hydraulic engineering are met thanks to the good mechanical and hydraulic properties of BETEX NW nonwovens.
BETEX TP Non-woven Fabrics
Thanks to their purely mechanical bonding, BETEX TP nonwovens offer very good technical solutions for filter and protection applications in civil engineering and hydraulic engineering.
BEGRID TG Geogrid
BEGRID TG geogrids are biaxially stretched, node-rigid geogrids made of polypropylene. Their monolithic structure and rigid cell geometry create an optimum frictional bond (interlocking) with the matched base course material, so that vertical loads are evenly distributed and transferred horizontally. As a result, initial trafficability can be achieved without major excavation work, even if the ground is heavily waterlogged.
PARAGRID/PARALINK Geogrid
PARAGRID/PARALINK are welded, laid geogrids consisting of highly stretched polyester with an extruded LDPE cover. Due to their high tensile strength, the grids are particularly suitable for special applications such as load transfer mattresses.
BEMAT Erosion Control Mats
BEMAT claw mats are three-dimensional erosion control mats consisting of a tangled layer of polypropylene monofilaments (PP). During the growth of vegetation, erosion channels are avoided, the soil is fixed and secured against washing out.
MACMAT R and R.E.C.S. COCCO erosion control mats
MACMAT R and R.E.C.S. COCCO are combined burrowing/erosion protection products made from double-twisted steel wire mesh with optional polymer coating and erosion protection made from synthetic or natural fibres. In addition to securing the topsoil layer until the embankment grows, they offer proven protection against burrowing and burrowing animals.
TERRAMESH steep slope systems
With TERRAMESH system solutions, steep slopes with front inclinations of up to 90° can be realised. The system consists of a reinforcing, duplex-protected steel wire mesh, a stiffening structural steel or gabion steel mat as permanent formwork, articulated inclination triangles as an installation aid, bracing hooks and erosion protection. The system components are supplied pre-assembled at the factory.
TERRABENT sealing steep slope protection
TERRABENT is a sealed earthwork construction with a greenable slope gradient of 70°. It is a combination of the statically effective GREEN TERRAMESH slope stabilisation system and the BENTOMAT geosynthetic clay liner.

Practical example
Braunsbach: Remediation after flash flooding
A stationary line of thunderstorms, which led to heavy rainfall, caused flash flooding in the Orlacher Bach and Schlossbach streams on 29 May 2016, which caused severe damage throughout the course of the stream and the centre of Braunsbach.
The GREEN TERRAMESH metallic geocomposite system was chosen for the embankment renovation on the L 1036 due to the high degree of pre-assembly and material robustness.
The construction of the wall began at the lowest point in the western section of the stream bed and was fanned out towards the east with berms. Thanks to the precise earthworks carried out by the contractor, it was possible to create a visually appealing embankment stabilisation in a very short time, even in the construction phase.
The highest section of the wall has 20 layers of GREEN TERRAMESH at 70°.
Sustainability
Sustainability is a key issue in the construction industry and is becoming increasingly important. With their versatile application possibilities, geobuilding materials offer ecological and economical solutions with high durability.
Natural erosion control
The frequency of extreme weather events can be directly linked to human-induced climate change. When planning flood protection measures, particular attention should therefore be paid to the selection of sustainable materials and low-emission system solutions. The use of geobuilding materials can significantly improve the energy balance of a structure, which leads to the conservation of valuable resources, a reduction in emissions and lower energy consumption. In many areas of application, geobuilding materials are a more environmentally friendly alternative to conventional construction methods.
Extremely flexible and mouldable
The products have undergone an environmental compatibility test in accordance with M Geok E 2016 and most of them are labelled with an Environmental Product Declaration (EPD).
The EPD provides comprehensive information on the environmental impacts that arise during the life cycle of a building product and thus enables a detailed analysis of the ecological footprint of the building material.
