More Over
According to DIN 4095, drainage layers must be arranged on ceilings that are to be covered with earth so that excess water can be safely drained away. As a rule, drainage layers are applied over the entire surface, not only under greenery, but also under pavements, terraces, play areas, etc. Floradrain® FD 60 neo, Stabilodrain® and Elastodrain® can even be used under pavements. With correspondingly high drainage elements, puddles can be bridged or the underside sewer system can be used for impoundment irrigation. This is of particular interest for intensive greening on zero-degree roofs. Drainage elements of the Floratherm® type even have a "general building authority approval" as additional thermal insulation.

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.
1) Installation:
Floradrain® FD 60 neo elements are installed with the diffusion openings (four holes per stud) facing upwards. The installation is carried out in a bond, and the FD 60 neo elements have connecting seams all around. The elements are to be laid in such a way that the larger fold is placed above the smaller one. This leads to a specific installation direction that must be maintained throughout the installation. Arrows are embossed on the edges to indicate the direction of installation.
After installation, the drainage elements must be covered immediately (UV protection!) and secured against blowing away. The latter can be done for a short time by filling it with water, provided that the actual load does not follow immediately.
If the Floradrain® panels are used under greening, the elements are always filled with a bulk material, preferably with Zincolit® Plus. Under slab coverings, the Floradrain® elements are filled with hard rock chippings (grain size ≤ 8 mm).
2) Cutting:
The drainage elements can be cut with a standard angle grinder, an electric cutter or a hot wire. 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.
Above roof drains, the drainage elements must be cut out according to the drain size.
Tool recommendation: Hand-held circular saw
