Roctest - Standpipe Piezometer | CP1 Get latest price

When installed as a piezometer, the filter is located in a sand intake zone at the location where pore-water pressure is to be monitored. A bentonite pellet or chip seal is placed over the sand intake zone and the remaining borehole is backfilled with grout.

A monitoring well installation consists of a filter-element attached to a riser, backfilled with sand to within a few meters of the ground surface. A bentonite seal at the surface prevents runoff water flowing into the monitoring well.

The CP1 consists of a porous plastic filter inside a perforated rigid PVC body.

Water enters the riser until the water pressure inside the filter equals the water pressure in the soil. A water level indicator can be then used to measure the depth of water.

Key Features:

• Excellent long-term realiability
• Simple readings
• Very economical
• Easy installation
