It is known that piezometric pressures can influence the strength of soil or rock, requiring that critical pore water pressures should be estimated during design of embankment fills and other structures. During construction, piezometers can be installed to monitor the pore water pressures with the dissipation of the pore water pressure over time used as a guide to consolidation rate. Thus, piezometers can be used to control the rate of fill placement during embankment construction over soft soils. Piezometers should be placed prior to construction in the strata/zones that contribute to settlement or shear strength. If the strata or zones are more than 10 feet thick, more than one piezometer should be placed to provide adequate coverage with depth. It is possible to install several standpipe piezometers in the same borehole; however, this requires more complex installation and introduces the possibility of crossflows from inadequate seals. Single piezometer installations are generally recommended.
