ADS meets Eurocode design loading

ADS StormTech below ground SuDS attenuation has been used within over 50,000 projects worldwide. Eurocode modelling demonstrates that the standard StormTech Construction Guidelines for minimum and maximum cover depths can be used for both shallow and deep applications.

This enables the SuDS attenuation system to be installed under roads with HGV traffic loading with a cover depth as shallow as 350mm. StormTech’s arch-shaped chambers are designed and manufactured to codes and standards published by the American Association of State Highway & Transportation Officials (AASHTO) and the ASTM international.

Thanks to the wide range of StormTech chamber sizes available design can be adapted to meet many site configurations. All sizes of the StormTech chamber have been analysed using a finite element analysis (FEA) model to Eurocode design principles. In the most demanding loading scenarios and the calculations proved that all StormTech chambers are structurally adequate for each of the four Eurocode load model cases.

StormTech is now available in the UK and other European countries. With no “equivalent” standard to the AASHTO or ASTM available in the UK, ADS commissioned a modelling study to demonstrate their performance under the Eurocode design methodology.
