Backfill materials around pipline in slope with high seepage
Backfill materials around pipline in slope with high seepage
(OP)
Excavation has been made in big slope with fine grained materials with high groundwater table (seepage)to fix the largte diameter watermain line. Go thing that the slope is highly vegetated and not exposed to mechanical load.
Any recommendation on backfill materials around and above the line. I guess native materials (even if they are highly compressible) would be the best.. since using sand will get eroded and other foreign materials may negatively change the seepage regime in the slope.
Thanks

You can also consider slope breakers (berms perpendicular to the slope) inside the trench and over the finished ground to reduce the runoff velocity and to divert water off the pipeline route and ROW.
Would be nice to hear back of your solution anyhow.
