   STRUCTURAL



   ecoAID® is an exceptionally strong system that can withstand high loading conditions (live & dead loads). The
   system draws its strength by distributing loads from above into the surrounding rock via soil arching.

   The ecoAID® chamber system has been designed, manufactured and structurally tested in accordance with
   ASTM F2787 (Standard Practice for Structural Design of Thermoplastic Corrugated Wall Stormwater Collection
   Chambers). As per ASTM F2787 ecoAID® has been designed and independently assessed using finite element
   analysis (FEA) and has undergone full scale field testing to validate model results. In addition, ecoAID® has been
   load tested to the Australian standard AS 5100.2 (Bridge Design Code) meaning ecoAID® is suitable to be installed
   under Australian roads and car parks.
