Cross Permeability

Cross Permeability Test Apparatus:-
Permeability of a geotextile must be substantially greater than that of the protected soil, so that water can pass freely from the soil through the fabric without build up of hydrostatic pressure. A high value of the permeability of the geotextile also infers that partial clogging will not reduce the permeability. The constant head test is carried out using a head of 50 mm of water.
