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 hard-earned cash!

A durable product design ensures sustainability. The GRAF EcoBloc system and the Vario 800 flex shaft system 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), only 7 kg (15.4 lbs) for one EcoBloc light unit.
Up to 97 % reservoir volume
The GRAF EcoBloc light has a gross volume of 225 (59.4 US gal.) and a reservoir volume of 219 (57.9 US gal.). With a reservoir volume in excess up to 97 %, it is a market-leading product. The EcoBloc variants and Inspect flex still offer a reservoir coefficient of 96 % despite their high load-bearing capacity.
Installation depth of up to 4 (13'1.4")
Even under very heavy loads, GRAF EcoBloc light modules can be installed at a depth of up to 4 (13'1.4"). This means that up to 9 layers are possible. Please consult GRAF when the installation depth is greater than 4
