More Over
Only when a filter fleece is covered with a filter fleece does a seepage layer become a filter-stable drainage layer, as required by "DIN 4095 – Drainage for the Protection of Structural Facilities". On drainage elements (Floradrain®, Floraset®, etc.), the SF. Nonwovens of the TG or PV type should be applied to drainage fills (especially if they consist of sharp-edged materials) and to Elastodrain®. The system filter fleeces are laid with an overlap of approx. 20 cm. Filter fleeces should not be exposed to direct sunlight for long periods of time, as they are not UV-stable.
Particularly in the pitched roof area, shear-absorbing elements such as Georaster® and Floraset® FS 75 are used, depending on the roof pitch. The jute erosion control fabric serves as additional erosion protection.
Technical Information
Installation Instructions
This installation instructions describe the essential steps of using this product. In addition, please observe the relevant standards and guidelines, in particular the provisions of occupational health and safety.
If there is a risk of storms, the installation should not take place.
Aquafleece® AF 300 is part of the "Climate Green Roof" and "Irrigated Extensive Greening" system structure and can only be used in conjunction with the 500-L2 drip hose and the Velcro strap.
1) Installation:
Aquafleece® AF 300 is laid loosely on drainage elements with a largely flat surface, e.g. Floraset® FS 50 / FS 75, Floradrain® FD 25 / FD 40 or Fixodrain® XD 20, with approx. 10 cm overlap. At the head joints, aquafleece® is also overlapped with approx. 10 cm. The fleece can be raised slightly on rising roof edges and components.
In order to ensure a full-surface loss-free supply of water, sagging or overhanging of the fleece must be prevented. A gravel strip will therefore be arranged at the edge of the roof and around penetrations.
To protect aquafleece® from being lifted off by the wind after installation, it is a good idea to wet it from above.
To protect against UV radiation, aquafleece® must be covered immediately after installation.
2) Cutting:
The fleece can be cut with a cutter knife (with a hard blade) or sturdy universal scissors. When cutting, care must be taken to ensure that the layers that have already been laid are not damaged under any circumstances! If damage does occur, it must be reported and repaired immediately.
Aquafleece® must be cut out over roof drains according to the drain size.
Tool recommendation: Slitter rewinder
