Description
Casagrande Piezometer / Standpipe System – Model EPP-10 / EPP-10SP
The EPP-10 porous tube piezometer is a traditional Casagrande-type mechanical instrument designed to measure pore water pressure in soil and rockfill formations.
It consists of a porous carborundum or allundum (Casagrande) tip, wrapped in geotextile cloth to prevent clogging, connected to PVC riser pipes through suitable adaptors and sealed with an end cap.
This system provides a simple, robust, and cost-effective solution for long-term groundwater and pore pressure monitoring in boreholes.
The EPP-10SP standpipe variant is primarily used for groundwater level monitoring. It comprises a PVC slotted pipe covered with geotextile, combined with a series of PVC riser pipes featuring built-in sockets and end caps. Both configurations are corrosion-resistant, easy to install, and require minimal maintenance.
