Features and Benefits
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!
Service life of over 50 years
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 4m
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
- 5 years warranty
The EcoBloc base plate forms the foundations of each EcoBloc system. Up to 10 EcoBloc modules can be fitted on one base plate.
The side faces are sealed with EcoBloc end plates. The EcoBloc system can be adapted to match individual requirements.
