Consolidated Undrained Triaxial Test Back Pressure Problem

[Geoaus]

Hi,

I am using an ELE Digital Tritest 50 System (which is unfamiliar to me) to test a CU TXL.

So far I seem unable to get past the consolidation stage, as overnight the back pressure creeps up to just below the cell pressure.

I have ruled out the bladder as a cause for this.

Any ideas?

I assumed you figured this out - but it sounds like you have a leak.
