Yixing Huadong Geotechnical Engineering Materials Co.,Ltd.

    The Na- bentonite waterproof blanket (GEOSYNTHETICE CLAY LINER) also referred to as GCL is a kind of new-type environmentally-friendly composite impermeable material successfully developed by our factory; The product is constructed of two layers of geosynthetic materials with high quality impermeable Na- bentonite filled and sealed between them and then produced through needle punch. This product features good overall stability, high tensile strength and shear strength; The impermeable bentonite sandwiched in the middle between the layers is inorganic material, which can expand after absorbing water to have impermeable gel structure with the ability for permanent waterproof performance. 

Product Application:
    The Na-bentonite waterproof blanket produced by our factory may be divided into GCL-NP type and GCL-OF type based on the different structures and the customer may choose the right type for use according to specific project;

GCL-NP type:
    With non-woven fabrics for the top layer, impermeable N-bentonite for middle layer and woven fabrics for the bottom layer, the GCL-NP type waterproof blanket is mainly used for impermeability treatment for the common base surfaces of artificial lake, artificial river, wastes landfill sites, roof gardens, swimming pools etc;

GCL-OF type:
    With non-woven fabrics for the top layer, impermeable N-bentonite for middle layer and woven fabrics for the bottom layer and finally the needle punch process and application of one HDPE membrane on the non-woven fabrics, the GCL-OF type waterproof blanket is mainly used for impermeability treatment for tunnels, subways, basements, underground walkways, various types of underground structures and waterscapes with sufficient underground source water etc;
