The hydraulic consolidation system (Rowe Cell system) is used because of its multiple drainage (up to eight
conditions) options as well as the capability to test large diameter samples using water pressure on a flexible
diaphragm. Furthermore, free strain and equal strain can be applied on the top of the sample through a flexible
platen or a rigid one. The FlowTrac II or III flow pumps automate the entire consolidation test using conditions
specified, with typical completion in 24 to 48 hours. The system automatically initializes, back pressure saturates,
and consolidates incrementally without intervention by the user.
