Permeability Testing Equipment
Permeability Testing Equipment
(OP)
Our company is in search of some user experience tips/hints/help with purchasing, or even making, our own laboratory permeability testing equipment.
What we are really looking for is some type of apparatus that allows us to utilize split spoon sample materials from our borings and compact them into some apparatus for permeability testing. Our struggle is that we are unsure of the amount of material that we actually have (not alot from split spoon samples) for performing a permeability test. This weighs in with the obvious of wanting to have relatively accurate test results and being cost-effective. Has anyone out there performed similar tests and have some ups/downs they can share.
Thanks!

Remolded permeability may not represent the formation permeability. The formation may have anisotropy - for example if the soil is fluvial, sedimentary or marine in origin. In these instances various sublayers create a difference between horizontal and vertical permeability. So, are you interested in vertical flow or horizontal flow? You will not discern such matters in remolded testing.
Remolding also requires some compaction water content - I mean you are not remolding at oven-dry moisture, eh? So, Mitchell, Hooper and Campenella did research on compaction moisture content and remolded permeability. In this research, they found that soil compacted wet of optimum returns a MUCH lower permeability. Like three orders of magnitude!
So, again, what's the end game? You looking for borrow in landfill construction? May be perfect!
