NexGreen Geo Safe 350

Name: NexGreen Geo Safe 350
Brand: NEXLER
SKU: T-NG0001-NX-0002

Protection and separation geotextile

Application:

Protection of waterproofing and thermal insulation against mechanical damage: in green roof systems, on ballasted roofs, on foundations, retaining structures, culverts and tunnels during excavation backfilling
Improvement of water drainage from green roofs
Separation and filtration layer in drainage systems to protect the drainage against mechanical damage and siltation
Separation and filtration layer between structural elements and fractions of different grain size during construction: footpaths, sidewalks, driveways and temporary roads, ground-level terraces
Erosion protection in combination with geogrids or geonets in slope and embankment construction
Protective layer in swimming pools and ponds to protect geomembranes and foils from mechanical damage

Properties:

Increased mechanical strength and resistance to damage and punctures achieved by calendering the geotextile
Ability to store water, further increasing the retention of the entire system
High filtration capacity even for fine particles due to reduced pore size
Resistant to weather and environmental conditions
Increased flexibility
Very good drainage properties
Elastic
Resistant to the effects of fungi and bacteria

Works should not be carried out during precipitation.
The geotextile should be laid in accordance with the technical design drawn up for the specific building, in accordance with the applicable standards and regulations.
Green roofs and ground reinforcement: When laying NexGreen Geo Safe 350, unroll from the roll while tensioning the unrolled layer. Weigh down the end of the roll to prevent the geotextile from moving. The geotextile must be laid out evenly over the prepared surface to ensure maximum contact with the substrate. Lay successive layers in the same direction maintaining a minimum overlap width of 20 cm.
Protection of waterproofing of foundations and building structures: Unroll NexGreen Geo Safe 350 along the vertical edge of the structural element while tensioning the layer being unrolled to ensure laying it out evenly without wrinkles. Connect adjacent sections with an overlap minimum 20 cm wide. Use suitable anchoring elements for fixing, i.e. starter strips, dowels, pins. The anchoring elements must be selected according to the layering in such a way that the continuity of the waterproofing layer is not compromised (penetration) during their fixing.
French drain: Lay NexGreen Geo Safe 350 in a single strip running along the bottom of the excavation or across using strips cut into suitable lengths. The excavation must have a slope for proper water flow. Select such width (length) of the geotextile that it allows subsequent tight surrounding of aggregate (gravel). Once the drainage pipe installation work has been completed, wrap the aggregate (gravel) with geotextile. Connect the edges of the geotextile mechanically, e.g. with steel pins. Then backfill with fill soil in accordance with the design specifications, ensuring adequate compaction to prevent soil settlement and maintain drainage capacity.
When connecting different sections, start laying NexGreen Geo Safe 350 from the side where the excavation is at the lowest level. This will allow proper water flow over the overlaps without pulling them upwards.
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.
