When the base surface of the GCL processing required flatness (maximum depth and the ratio of the minimum diameter pits) basal plane is not more than 1/6, and require smooth transition, with no right angles and other parts. But for comparison rules bump ups and downs pile structure to meet the requirements of surface flatness turning radius can not be less than 40 cm, this time to be on the bottom and side walls connecting the key parts of treatment to ensure the floor and side walls of the bentonite blanket smoothly transition. In addition to the requirements of tight waterproof blanket in the grass surface without any major folds, but also properly handle the rough parts of the surface of the substrate. Because in the sprayed concrete base laid directly bentonite blanket, there is often a lot of tiny floating blanket body parts between the contact surface with the grass roots, not fully dense paste, so that when the bentonite expands, it will first fill these tiny holes, resulting bentonite particles loss of professional waterproof blanket factory, while the water table once again change the professional waterproof blanket, bentonite particles will be taken away, the impact of a permanent blanket of bentonite waterproofing effect. The top layer is a high density polyethylene (HDPE) film is lower for non-woven fabric, impermeable layer of sodium bentonite has a textile. The waterproof excellent results sodium bentonite, with a special acupuncture fixed between high strength geotextile nonwoven fabric and then covered with a layer of high-density sticky polyethylene (HDPE) film. This product has a stronger ability than ordinary water seepage of sodium bentonite waterproof blanket. For applications that require high water seepage areas such as: tunnels, subways, basements, underground passages kinds of underground structures and groundwater resources are abundant water features works deal with seepage leakproof. GCL chosen sodium bentonite particles inflatable water more than 24 times, to form a homogeneous high viscosity and low fluid loss colloidal system, in two layers of geotextile limit the role of the bentonite changed from disorder orderly expansion, sustained swelling bentonite layer itself result is to achieve dense latest professional waterproof blanket, which has a waterproof effect. GCL is a cross between an impermeable liner GCL (site of compacted clay liner liner) and polymer materials ---- between geomembrane. Because sodium bentonite Department of Natural inorganic materials, even after a very long period of time or the surrounding environment changes Special professional waterproof blanket, aging or corrosion will not occur, so Bentonite is a natural inorganic material, harmless, non-toxic, no environmental special effects, with good environmental performance. GCL by the production process can be divided into: acupuncture sodium bentonite waterproof blanket, coating method acupuncture sodium bentonite waterproof blanket and gluing sodium bentonite waterproof blanket.
