In order to obtain reliable pore pressure readings, it's essential that the filter elements are completely saturated and that any air is removed from the pore pressure chamber of the CPT cone. For this purpose, we offer two different saturation systems.
The first option is using a saturation kit to saturate the filter rings (whether brass or HDPE) either in the workshop or on-site. Mounting of the tip and filter assembly under oil covering can then be performed by placing a customised stainless steel funnel over the cone body. This is achieved using our cost-effective saturation system.
However for optimum saturation when pore pressure data is crucial, such as when performing Application Class 1 tests, the entire cone with the filter ring can be placed in a saturation chamber to de-air them together. This is achieved using our advanced saturation system.
