anti-permeability ability, flexibility is good, can accept the uneven settlement foundation, and can prevent loss of earth mater
GCL(Bentonite compound waterproof blanket/(mat) ,the width is up to 6 M , the length is 60 M (according to the customer's requirements), the permeability coefficient 1.25-3.54 x 10-9 CM/S, CBR strength against the broken 1.2 KN, punctured strength 0.34 KN,have the good comprehensive properties. GCL we produce is good quality, anti-permeability ability, flexibility is good, can accept the uneven settlement foundation, and can prevent loss of earth material, and have the good healing ability to crack defects.
