Blue Roof Meander FKM 60 System Solution

CHARACTERISTICS

System solutions with defined water retention
High level of reduction of of water discharge during high intensity rainfall whilst retaining good drainage (even for large roof areas)
Peak discharge
Water storage and discharge delay.
Suitable for blue roofs
For green and gravel roofs
Meander FKM 60 prevents accumulation of water in cases of ponding in depths of up to 40 mm

Specification

TECHNICAL DATA
Weight *: starting at 120 - 140 kg/m² or 1.2 - 1.4 KN/m²
Layer height: 120 mm
Roof pitch: 0-5° (0-9 %)
Vegetation form: herbs-grasses-sedum
Water retention: ≥ 80 %
Discharge coefficient: Cs=0.05 - 0.17 **/****
Water storage: ca. 38 - 53 l/m² temporarily
Discharge yield ***: 15-51 l/s x ha
* Depending on the load capacity of the substructure, Optigreen "High Density (HD)" or "Low Density (LD)" substrates can be used. Weight specifications refer to saturated conditions; dry weight is approximately 60 - 70 % of the saturated weight. In accordance with the requirements of the FLL guideline, the specified weight does not take temporary water accumulation into account.
** For the calculation of the dimensions of the pipe we recommend the discharge coefficient Cs = 0.1. Cs= 0.01 determined for 2 % according to the FLL guideline.
*** Determined according to FLL discharge coefficient measurements using a 15-minute reference rainfall r(15) = 300 l/s x ha.
**** Depends on slope and system solution. Determined at 0° according to FLL guidelines
