Bentonite Water Stop Geosynthetic Clay Liner(GCL) 1.Width:4- 6m 2.Weight:6000g/SQM 3.Good leakage performance Product introduction :Geosynthetic Clay Liners Features:A) It has good tightness, waterproof and water isolation performances, bentonite forms dense and non-permeation gel isolation film layer of bentonite under normal water pressure status.B) It has good flexibility and can adapt uneven sedimentation well.C) It has long waterproof capacity; bentonite is natural inorganic mine material and will not have corrosion and aging phenomena.D) Its water absorption thickness increases several times, so it isn't easy to break, it has own repair capacity even under the situation of breakage.Advantages:A) Foreign and domestic advanced production equipments are used, its knitting has disorderly and irregular knitting type, can prevent rolling and dropping of bentonite and is good for uniform absorption.B) Since production equipment is advanced, its produced width can be adjusted within the range of 2m-6m according to users' requirement.C) Due to increase of width, joining area decreases greatly, this can save material for the users and avoid unnecessary waste.D)   Application:Permeation proof projects such as landfill, golf course, man-made and hydropower station.
