LORO-X DUOSTREAM cascade drainage
Only 2 collecting lines (streams) over several floors with multi-storey drains
The LORO-X DUOSTREAM cascade drainage system with multi-storey drains drains the roof and all roof terraces below with just two collecting pipes (DUOSTREAM). One stream for the main drainage and one stream for the emergency drainage from the roof to the ground floor.
The first stream with multi-storey drains without a weir for the main drainage drains the roof and the roof terraces into the underground pipe with a high-performance safety overflow (HSÜ). The second stream with multi-storey drains for emergency drainage (with weir) drains the roof and the roof terraces into the open air onto an area that can be freely flooded without causing any damage.
Two models of the 88 Rainstar-Distant multi-storey drain series are available for horizontal deflection: The "Inside the thermal insulation" model guides the horizontal deflection over the roof terrace within the thermal insulation. Alternatively, the "Above the waterproofing membrane" model can be selected if the horizontal deflection is to be guided above the waterproofing membrane.
Alternative multi-storey drains:
- With Series 43 Attika-Direkt (55mm penetration depth)
- With Series 88 Rainstar Distant (above or below the sealing level)
LORO-X series 88 cascade drainage
with one continuous line each for the main and emergency drainage from the roof surface and several roof terraces with a cascade-like arrangement according to the direct drain principle
