permeability of clay barrier
(OP)
Question - I have to design a 0.5m thick cap on a waste rock dump. Criteria is 10-9. My materials are 10-8 What extra thinned do I need to meet same infiltration rate ?

Now, what's optimum? Bear in mind if the requirement is 95 percent compaction, the optimum moisture content for 95 percent compaction is not the same value as the optimum moisture content for 100 percent compaction. The ASCE journal article talks about that too. Basically, for the lowest possible permeability value you need to compact the sample at about 90 percent saturation.
f-d
p.s., try to avoid using the words, "Infiltration" and "permeability" interchangably. They mean different things!

We have a spec of 10-9 in the clay barrier, but I have 10-8 materials - so how do I convince them that we can construct a cap with the same rate of infiltration from rainfall ?. Do we increase then depth ?
