Green Roof Water Storage Panel

Features

The greening of roof surfaces and thus the creation of new biological habitats is gaining ever greater importance and is often the only possibility of counteracting the disadvantages of progressive sealing of soil surfaces. The technical properties of the Ritter roof rainwater storage panel create the best preconditions for long-lasting functional greening. The outstanding features are the water storage facility, of around 27 litres/m², and the high degree of diffusion capability.

What functions does it perform?

The roof rainwater storage panel fulfils two fundamental functions:

• The large storage capacity facilitates even and delayed drainage of rainwater, thus improving the microclimate for the long term.
• The high degree of diffusion capability on the underside of the panel means that water run-off is maintained permanently over the entire surface.

What applications does it suit in particular?

• For intensive or extensive greening
• For flat roofs of all sizes such as underground car park roofs, industrial roofs, roofs on residential housing, prefabricated garages, car-ports, etc.
• For pitched roofs with inclinations of up to 25°
• For partially greened roof surfaces (greening strips, planting islands, etc.)
• Inverted (protected membrane) roofs

The advantages of the Ritter roof rainwater storage panel:

• Environmentally neutral, long-life HD-PE material (polythene)
• Easy-laying format; approx. 57 x 38 cm
• Delayed water run-off following heavy rain
• Around 27 litres water retention per m² (depending on the filler materials)
• Enforced drainage via 277 drainage holes per m²
• Can be driven over with installation equipment for top filling (e.g. Bobcat or similar)
• High load capacity: approx. 204 kN/ m²
• Low logistics expenditure for transportation: approx 62 m² on a single palette
• Capable of being recycled at all times
• High degree of diffusion capability on the underside
