Does Stratum have other applications e.g. on buildings, being used in lieu of reinforced concrete rafts, or is it not that stiff? If suitable Stratum could be used as the 'raft' & a normal ground bearing slab perhaps with a geo-grid reinforced hard core crust?
Thank you for your question. As expected we have received a large number of questions following the webinar so will be working our way through these as soon as possible.
My interest is using the system to span over potential mine subsidence land down here in Cornwall. I downloaded a case study backalong where this 'stratum' structure was used in the past (in Scotland from memory, I can dig it out). Cornish mine features are invariably narrow linear workings, small tunnels and small shafts (say 4.0mx4.0m. Would the system be able to span small voids (how big) if only for short duration to allow mitigation to be implemented if such events occured? I can send photos to show examples if req'd.
Do we need to lay a non woven geotextile mat below the cells as a filtering membrane so as to prevent mud pumping?
