Rainwater tank (underground)
RONDUS
GRAF
Flat design
The flat design of the Rondus ensures a sensationally low installation depth and less earth therefore needs excavating. Compared with a classic rainwater tank, the amount of earth excavated is reduced by around 40 %. But if combined with the telescopic dome shaft, all parts carrying water are still in the frostfree area.
Lorry-bearing
Do you want to fit the Rondus underground tank in your courtyard entrance? When combined with the cast telescopic dome shaft, the Rondus is suitable for vehicle loading – the Rondus plus can even be lorry-bearing with an axle load of max. 8 t (if combined with the BEGU telescopic dome shaft).
Groundwater stable
Thanks to its special design the Rondus underground tank is so stable that it can be fully fitted in groundwater, stratum water and cohesive soils (e.g. loam) (in combination with anti-buoyancy measure). The maximum ground water level corresponds to the top edge of ground.
