Constant Head Permeability using a permeameter (up to 4 days duration)
(BS1377 : Part 5 : Clause 5 : 1990)
£ 120.00
Extra over days in excess of initial 4 days £ 20.50 per day
Remoulding specimen £ 15.00 (always required)
Notes
This test is suitable only for samples with relatively high permeabilities (coefficients in the range 10-2m/s to 10-5m/s: typically no finer than fine sand / coarse silt). For lower permeabilities, usually when checking that the material is impermeable enough to meet a specification, the Triaxial Permeability is a more appropriate test.
