Piezometers measure the pressure of the water in the compressible layers.  By monitoring this pressure and tracking the dissipation, the project engineers can determine that the settlement is complete, and surcharge removal or additional construction can commence.  When used in conjunction with settlement monitoring plates, a redundant system of site monitoring ensures completion of the settlement waiting period.

Nilex can install pneumatic piezometers concurrently with the wick drain installation to facilitate monitoring without the expense or failure rate of the vibrating wire type or the expense and coordination of subcontracting to another company.
