Effective solutions for delaying runoff and meeting discharge restrictions.
With our retention roof systems, green roofs and intelligent rainwater management work together effectively and sustainably. For a better microclimate and in line with the concept of the sponge city. We offer you effective solutions for delaying runoff and complying with discharge restrictions or throttled runoff from the green roof. For both extensive and intensive green roofs.
Retention roof Meander - the discharge delay system with low peak discharge coefficient Cs
Delay, attenuation and reduction of runoff from the green roof structure, even with a slope, free drainage.
Retention roof Meander FKM 30
Defined discharge coefficient Cs = 0,01.
Retention roof Meander FKM 60
Defined discharge coefficient Cs = 0,17.
Retention roof Flow Control - the system for throttling the roof outlet
Discharge restriction, max. discharge adjustable by means of a restrictor at the roof inlet. Requires a slope-free sealing level.
Retention roof Flow Control Extensive
Adjustable discharge yield in l/s.
Retention roof Flow Control Intensive
Adjustable discharge yield in l/s.
Public roof Retention
The roof with retention space that can be walked and driven on
Public roof Retention
Peak discharge coefficient can be set object-related.
