blueprint drawing of large test facility für underground infrastructure

25 years ago, a hole was dug in the floor of our laboratory, this year we made it bigger – why, you may ask? Well, it’s because this Large (1:1 scale) Test Facility proved to be very adaptable for successfully comparing solutions to ageing sewer issues for sewer network owners. Extending it, as part of our current investment in improving existing facilities and construction of our new Heavy Rain Lab,…

Around the world sewer network owners are struggling to address the options for replacement or rehabilitation of ageing pressure sewers. Often the preferred solution is to dig them up and replace them. Rehabilitation solutions using trenchless technology tend to be used only when it is too difficult to excavate, but sewer network owners are interested in using such technology more often. First, they need to fully understand it.

We have evaluated with sewer network owners the suitability of “Flowable Backfill” for use sewer trench backfilling in an IKT-Compare evaluation of this technology. Five products were compared and all were found to flow well into 1:1 scale excavation pits in our large-scale test facility – around pipes and manholes shafts and into every corner of the simulated trenches. However, during the subsequent performance tests it became increasingly clear that…
