Product Code: EKE 250 The tests for permissivity and transmissivity help in comparing one fabric to another, but gives no indication of the hydraulic behaviour of the composite soil-fabric system. Under steady state and reversing flow conditions, fabric clogging or binding causes a decrease in water flow rate and corresponding increase in hydraulic head loss through the geotextile. When the potential for fabric clogging is significant, clogging resistance of filter fabrics should be evaluated to ensure adequate long term filter performance. As the clogging is highly soil dependent, soil fabric permeability test is suggested to determine the long term flow capability of a geotextile.   Specimen diameter : 100 mmMould for : 10 cm dia x 11.2 cm high compaction of soilHead of water : Upto 37.5 cmEKE 13111 Overhead Tank   EKE 251 Gradient Ratio Test Apparatus The US Army Corps of Engineers established a direct measure of geotextile clogging potential. They defined it as gradient ratio which is the ratio of hydraulic gradient through the geotextile plus 25.4 mm of the soil to that of hydraulic gradient through the adjacent 50.8 mm of the soil.It is determined after 24 hours of flow.Specimen diameter : 100 mmMould for : 10 cm dia x 11.2 cm high compaction of soilHead of water : Upto 37.5 cmEssential AccessoryEKE 13111 Overhead Tank
