Soils - Determination of the Coefficient of Permeability by the Lefranc Method

Standard CAN/BNQ 2501-135
Soils - Determination of the Coefficient of Permeability by the Lefranc Method

This national standard specifies the test method used to determine the coefficient of permeability of the soil around a cavity (a “lantern”) created under the end of a drill casing driven by ramming, a test method particularly suited to soils with a coefficient of permeability greater than 10-7 m/s. Specifically, the standard deals with five main elements:

  • apparatus and installation method;
  • choosing a test method;
  • procedure (constant head test and falling or rising head test);
  • calculating and expressing the results (constant head test and falling or rising head test);
  • test report.
