Description by Manufacturer

CASAGRANDE FILTER

Application

Simple and economic measurement of groundwater pressures in soil and rock can be carried out using Casagrande type piezometers. Typical application include:

Monitoring of dams, reservoirs & embankments
Slope stability
Groundwater levels for dewatering & drainage
Groundwater sampling
Permeability testing
Contaminated soil monitoring

Geovan Porous Filter Tip is made up of low air entry porous plastic elements which are connected to standpipe tubing and lowered into a predrilled borehole. Alternative types may be driven or pushed into soft soil.

Where Casagrande type piezometers are being installed then the porous element is surrounded by filter sand and a Bentonite seal placed above this response zone.

Water level measurements are normally taken using a water level meter or in the case of artesian pressure a Bourdon pressure gauge is attached to the top.
