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.

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.
1) Installation under asphalt pavements:
The heat-resistant fleece is preferably used under asphalt pavements in semi-rigid construction or under mastic asphalt. The installation is carried out loosely with approx. 20 cm overlap on the already sealed roof. On rising roof edges and components, the fleece can also be lifted up a little. Elastodrain® EL 202 panels are laid over it (see installation instructions Elastodrain® EL 202). A second layer of heat-resistant TVH 200 release fleece is laid on top. The asphalt base course and the asphalt surface course will be placed directly on top of that. It should be noted that the asphalt base course is carried out using the manual paving method with static compaction.
When paving mastic asphalt as a drivable surface, the lower layer should not be thicker than 6–8 cm and should be waited for 0.5–1.0 hours before installing the additional layer(s).
To protect against UV radiation and blowing away, the fleece 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.
The fleece must be cut out over roof drains according to the drain size.
