  • High storage volume
    GRAF infiltration modules have three times the storage volume of a standard gravel infiltration ditch. One module therefore takes the place of around 1300 kg (1,4 tons) of gravel or a 50 m (164') drainage pipe. Since you don‘t have to excavate so much soil and enjoy great value for money compared with a standard gravel infiltration ditch, the GRAF modules save you hard-earned cash!

  • Service life of over 50 years
    A durable product design ensures sustainability. The GRAF EcoBloc system and the Vario 800 flex shaft system is designed for a service life of over 50 years.

  • Easy to install
    The modules are fitted simply, at speed and in various ways. They can be installed without heavy machinery – one EcoBloc Inspect flex module weighs just 8 kg (17.6 lbs), even only 7 kg (15.4 lbs) for one EcoBloc light.

  • Up to 96 % reservoir volume
    The GRAF EcoBloc maxx has a gross volume of 225 litres (59.4 US gal.) and a reservoir volume of 217 litres (57.3 US gal.). The EcoBloc variants maxx and Inspect flex still offer a reservoir coefficient of 96 % despite their high load-bearing capacity.

  • Installation depth of up to 5 metres (16' 4.8")
    Even under very heavy loads, GRAF EcoBloc Inspect flex modules can be installed at a depth of up to 5 metres (16' 4.8"). This means that up to 13 layers are possible. Please consult GRAF when the installation depth is greater than 5 metres.

  • 5 years warranty

Eco-friendly product – green logistics:

  • Stackable

    To save space during transport, the EcoBloc maxx and EcoBloc light modules are stacked into each other. This minimizes transport costs, storage space in stock and CO2 emissions.
  • Easy installation
    The EcoBloc base plate forms the foundations of each EcoBloc system. Up to 13 EcoBloc modules can be fitted on one base plate.
  • Ready
    The side faces are sealed with EcoBloc end plates. The EcoBloc system can be adapted to match individual requirements.
