KEY FEATURES & BENEFITS

1   Corrugated Arch Design – incorporating a true parabolic inner profile for
    optimum load-shed via soil arching, with boxed-out corrugations providing arch
    stiffness and rigidity ensuring structural integrity over the system’s 100 year+
    design life.                                                                                 3
2   Six slots per corrugation – Reducing chamber emptying time.




3   End Cap to close out row – Flat end cap base design ensuring no rotation of end
    cap and chambers occurs when backfill material is placed. The end caps have cut
    out guides accommodating pipe inlets up to 625mm outside diameter.



4   Moulded side entry ports (100mm Ø or 150mm Ø) – Integrated lateral pipe
    ports allowing side entry lot connections directly into the ecoAID system and also
    used to aid system equalisation and water distribution.


5   Moulded vertical entry ports (100mm Ø or 150mm Ø) – Integrated vertical pipe
    ports to accommodate breather pipes for system ventilation, inspection access



                                                                                                 7
    and used for water extraction pipes on stormwater harvesting applications.



6   Keyed feet with stiffeners – The flat keyed feet of the chambers are locked
    into place by the embedment aggregate preventing movement during backfill
    placement and compaction.



7   Each chamber weighs only 15 kg – Can be installed by one person ensuring safe
    and rapid installation.                                                                      8
8   Single or double layer configuration – Can be designed and installed in two
    layers to increase effective volume.
