Discount wholesale Geo Composite - Clay Geosynthetic Barriers – Yingfan Detail:

Product Description

We, Shanghai Yingfan Engineering Material Co., Ltd., is a clay geosynthetic barriers manufacturer in China. This product is also called “geosynthetic clay liner” (GCL), “clay blankets”, “bentonite blankets”, “bentonite mats”, “prefabricated bentonite clay blankets” and “clay geosynthetic barriers”, the latter currently favored by the International Organization for Standardization (ISO).

Clay Geosynthetic Barriers Introduction

It is bentonite geo-synthetic waterproofing barrier that often replaces thick layers of expensive compacted clay.

It is sandwich-made of a non-woven geotextile, a natural sodic bentonite layer and a polypropylene woven sheet.

Due to the hydro-expansive characteristic of bentonite (Bentonite composed predominantly (>70%) of montmorillonite or other expansive clays) and the needle punching method of manufacture which gives the resulting composite material shear strength, a critical feature for installation on slopes, our clay geosynthetic barriers can be used in many erosion control requested civil engineering.

Its performance can meet or exceed GRI-GCL3 and our national standard JG/T193-2006.
