	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

	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.
