EcoBloc maxx

EcoBloc maxx infiltration bloc
Infiltration bloc for storage and/or infiltration of rainwater and for positioning on EcoBloc maxx base plates
– see separate item – or for creating multiple layers on other EcoBloc maxx infiltration blocs.
Inspection and cleaning is possible by combining with EcoBloc Inspect flex infiltration blocs and the
Vario 800 shaft system.
The open structure ensures a three-dimensional flow of water through all system components.
Infiltration blocs are laid to give sufficient coverage by linking with EcoBloc connectors in a horizontal
direction – see separate item.
Multiple layers of infiltration blocs can be laid, no connectors needed for the vertical connection.
Long-term load-bearing capacity up to heavy-duty 60 tonne lorry verified.
Max. installation depth up to 5 m.

EcoBloc connectors
Connectors for joining multiple components of the EcoBloc family, where GRAF EcoBloc system components are laid to provide coverage over any surface area. One connector is required per contact surface
between two connecting blocs (side by side and end by end) on every vertical layer of the system components.
Technical data:
Dimensions (LxWxH): 68 x 26 x 38 mm
Material: Polypropylene PP (100 % recyclable)
Colour: grey

GRAF-Tex geotextile
Graf-Tex geotextile (8 ounce, non-woven geo-textile fabric), 100 % polypropylene filter membrane, mechanically needle-punched to form continuous filament. Rot-proof material between soil and infiltration
system prevents infiltration layers from silting up. The Graf-Tex geotextile ensures long lifetime, consistent infiltration and high permeability.
Technical data:
Opening width: 100 µm
Water permeability coefficient kv (s = 20 kPa): 1.0 x 10-3 m/s
Tensile strength (lengthwise / crosswise): 15 kN/m / 15 kN/m
Punch push-through force (x-s): 2.0 kN
Weight: 200 g/m²
Robustness class: 3
Roll material: Roll width 5 m (196.9”)
Product: GRAF-Tex geotextile

Deaeration end DN 100 (4” pipe)
Deaeration end DN 100 (4” pipe) should always be installed for attenuation/infiltration systems in the
event of heavy inflow of rain/surface water or undersized house venting installation.
Technical data:
