The third generation of GRAF infiltration and attenuation system

• Universal use: For rainwater infiltration, retention or rainwater harvesting
• Twice the volume per truck: To save space during transport, two EcoBloc Inspect flex modules are stacked one inside the other. This halves transport costs and CO2 emissions.
• Easy to inspect: The standard inspection channel allows the entire infiltration system to be effectively monitored. The ability of the EcoBloc Inspect system allow access by inspection cameras that are commonly found on the market. This has been confirmed, by several independent testing authorities.
• Can be cleanded by high pressure jetting: GRAF EcoBloc Inspect system can be easily
  cleaned by high pressure jetting.
• Highly flexible: Each EcoBloc Inspect flex module has a volume of 205 l, a area of 800
  x 800 mm and a height of 320 mm. The system size and loadbearing can be adjusted individually to suit requirements of traffic and of non-traffic area.
• Installation depth of up to 5 metres: Even under very heavy loads, GRAF EcoBloc Inspect system can be installed at a depth of up to 5 metres. This means that up to 14 layers are possible.
• Connection up to DN 200: Large infiltration volumes require large pipe cross-sections. This isn‘t a problem for GRAF EcoBloc Inspect: it has DN 110, 160 and 200 connections on all sides. DN 100 connections are positioned eccentrically
  at the side for complete deaeration.
• Designed for decades of use: A durable product design ensures sustainability.
  Built to offer double safety, the GRAF EcoBloc Inspect is designed for a service
  life of over 50 years.
• High infiltration rate: The GRAF EcoBloc Inspect system is designed to have high rate of infiltration and barrierfree inspection.

1. Stackable
   To save space during transport, the EcoBloc flex modules are stacked into each other. This minimizes transport costs, storage space in stock and CO2 emissions.
2. 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 8kg (17.6lbs)
3. Lorry-bearing up to 60tons
   The EcoBloc Inspect flex has a heavy-duty lorry-bearing capacity of 60 tons with an 800mm (2' 7.5") earth covering

Various applications: Rainwater infiltration, Stormwater attenuation, Rainwater harvesting

• 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 maxx module weighs just 9 kg (19.8 lbs).
• 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 variant maxx 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 maxx 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.

1. Stackable
   To save space during transport, the EcoBloc maxx modules are stacked into each other. This minimizes transport costs, storage space in stock and CO2 emissions.
    
2. 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.
    
3. Ready
   The side faces are sealed with EcoBloc end plates. The EcoBloc system can be adapted to match individual requirements.

  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 97 % reservoir volume
  The GRAF EcoBloc light has a gross volume of 225 litres (59.4 US gal.) and a reservoir volume of 219 litres (57.9 US gal.). With a reservoir volume in excess up to 97 %, it is a market-leading product. 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 4 metres (13'1.4")
  Even under very heavy loads, GRAF EcoBloc light modules can be installed at a depth of up to 4 metres (13'1.4"). This means that up to 9 layers are possible. Please consult GRAF when the installation depth is greater than 4 metres.

1. Stackable
   To save space during transport, the EcoBloc light modules are stacked into each other. This minimizes transport costs, storage space in stock and CO2 emissions.
2. Easy installation
   The EcoBloc base plate forms the foundations of each EcoBloc system. Up to 10 EcoBloc modules can be fitted on one base plate.
3. Ready
   The side faces are sealed with EcoBloc end plates. The EcoBloc system can be adapted to match individual requirements.

The Vario 800 flex shaft system can be directly installed in an infiltration or detention system with EcoBloc

• Shaft can be fully integrated, therefore no additional excavation is required
• Various applications (e.g. as an inlet shaft, detention shaft or inspection shaft)
• Can be positioned in any location in the ditch grid
• Can be combined with proven GRAF covers and shaft components
• Connections via the inlet module can be rotated 360°
• Very good accessibility with 600 mm (23.6") clearance
• DN 200 (8") / 300 (12") / 400 (16") connection surfaces
• Shaft volume can be calculated into the assessment of the ditch volume

Space-saving and cost-efficient. Specifically designed for use in private and rural areas. 

• The Graf infiltration tunnel has been mainly designed for the use in private and rural areas
• The system which consists of one or several tunnel modules and two end plates can be extended at will
• The laying is realized in one or more lines of the same level
• As the weight of one module is only 11 kilos, the handling of the infiltration tunnel is excellent
• The surface beyond the tunnels is lorry-bearing which offers versatile possibilities 
• The infiltration tunnel can be loaded permanently up to 59kN/sqm and thus is also suitable for lorry-bearing
