Geocellular Structures; Design, Specification and Maintenance

Attenuation is a requirement for most construction sites across the UK. This is essential to deal with Volume Control set out in DEFRA’s Sustainable Drainage Systems - Non-statutory technical standards for Sustainable Drainage Systems, the new London Plan and the Quantity Element of The SuDS Manual. Geocellular Storage Systems are a large part of this Attenuation capacity. It is very important that the design and installation of these systems is carried out correctly.   

Guidance and calculations for infiltration and attenuation are looked at from first principals, leading up to how free online software can be used. Structural calculations and the importance of FOS used in C680 will be highlighted along with what the future holds for C737.  

We will then look at specification and the importance selecting the correct type of installation with a key focus on inspection and maintenance for any potential approval and adoption process. Finishing on a flurry of case studies for a variety of different scenarios. at using Geocellular storage structures for both tree root protection systems and briefly roof gardens. Finally, looking at Maintenance, adopted systems and why designing for the future management of a site is of vital importance.
