Works should not be carried out during precipitation.
The substrate on which NexGreen Road 440/75/13 is laid should be even, clean and free of sharp protruding edges, and properly compacted. Stones, wood and organic parts should also be removed. Spread a suitable geotextile, e.g. NEXLER NexGreen Geo 110, on the prepared substrate. For escarpments and slopes - dig anchor trenches at the foot of the slope, as well as at the top of the slope, in which the geogrid will be fixed.
Green roofs
Perimeter drain and drain lines: The geogrid should be installed by stretching it over a suitably prepared substrate. When stretching the geogrid, ensure that it is evenly distributed and tensioned. The individual modules should be combined on an ongoing basis. Once the geogrid has been properly laid out, its cells can be filled with suitably selected aggregate.
Pitches on roofs: The geogrid should be installed by stretching it over a suitably prepared substrate. The installation of the geogrid should start from the top of the slope, anchoring it at the top with installation bars. Anchoring is necessary to prevent the geogrid from moving during further installation. When stretching the geogrid, ensure that it is evenly distributed and tensioned. The individual modules should be combined on an ongoing basis. Fill the geogrid cells in the direction from the foot of the slope to the top of the slope.
Escarpments and slopes
The geogrid should be installed by stretching it over a suitably prepared substrate. The installation of the geogrid should start from the top of the slope, anchoring it at the top. Anchoring is necessary to prevent the geogrid from moving during further installation. When stretching the geogrid, ensure that it is evenly distributed and tensioned. On an ongoing basis, join together the individual modules should and attach the installation to the substrate. After the geogrid has been properly anchored in the ground, backfill the anchor trenches first. At the very end, fill the cells of the geogrid. Fill in a direction from the foot of the slope to the top of the slope.
Horizontal surfaces
The geogrid should be installed by stretching it over a suitably prepared substrate. When stretching the geogrid, ensure that it is evenly distributed and tensioned. On an ongoing basis, join together the individual sections should and attach the installation to the substrate. Once the geogrid has been properly laid out and anchored, its cells can be filled.
Retaining structure
The slope reinforcement consists of properly stacked layers of filled geogrid. On the prepared substrate, together with the laid NexGreen Geo 110 or NexGreen Geo Safe 350 geotextile (depending on the required strength of the geotextile), the construction can proceed. Installation should start from the bottom of the slope, placing the geogrid in the designed position. Once the geogrid has been stretched, use separation and installation bars to stabilise it (Figure 2). Fill the properly laid geogrid with suitable material, remove the separation bars and carefully compact the material. Remove excess material before laying the next layer of geogrid. Analogically, proceed to lay the next layer of geogrid. Lay successive layers of geogrid in a staggered manner.
Every few levels of geogrid, spread a layer of geotextile according to the design guidelines. The retaining structure must be constructed in accordance with the technical design, which specifies the number of levels of geogrid, its parameters and the additional reinforcement necessary to ensure the stability of the wall. Properly designed drainage is required to ensure the stability of the wall.
Fill the geogrid with suitable material according to the design guidelines. The size and type of aggregate should be selected according to the application. When filling the geogrid, care should be taken to ensure that there are no voids and the material is compacted evenly.
Before use, please read the application details in the product's Technical Data Sheet.

A roof with a vision – green solutions for investments

Green roofs in modern construction are not a passing trend, but a real market need driven by climate, urbanisation and regulatory challenges. They are a key element of sustainable development strategies, not only distinguishing investments on the market, but also having a real impact on their value and functionality. It is a space where ecology meets long-term safety and technical durability.
