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.

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.
1) Installation:
The installation is carried out in a bond, for this purpose the elements are laid next to each other with overlapping edges. It is important to ensure that the depressions and characteristics are placed on top of each other appropriately.
When used under pavements and road surfaces, the studs are laid upwards. In order to store more water, the element is laid under greenery with the nubs downwards.
After installation, the SD 30 elements can be backfilled for positional stability in windy conditions (zincolite®, chippings, ...). If the actual load cannot be applied immediately, it can also be filled with water for a short time.
Under road surfaces, backfilling (chippings) is always carried out. Stabilodrain® SD 30 elements can also be driven on carefully when unfilled. However, it must be ensured that the substrate is correspondingly load-bearing.
A vibratory plate can be used to compact the ballast, but it must be taken into account that the work is taking place on a roof surface. Select the vibratory plate accordingly so that the vibrations of the ceiling plate do not become too great.
2) Cutting:
The drainage elements can be cut with a standard angle grinder, an electric cutter or a hot wire. It is also possible to cut to length with a circular saw or an electric foxtail.
When cutting, care must be taken to ensurethat 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.
3) Under pavements and road surfaces:
Installation with the studs facing upwards
4) Under greening:
Laying with the studs downwards
5) Cut by overlapping 6
) If laid in a bond, an offset in 0.5 m steps is possible!
Tool recommendation: Hand-held circular saw
