Taian Hongyuan Geosynthetics Co., ltd. specializes in the production of geomembrane composite with non-woven. As a professional geomembrane composite with non-woven manufacturer, it has been engaged in the wholesale of geomembrane composite with non-woven for many years. Today, we will learn from you how to strengthen the waterproof function of geomembrane composite with non-woven.
1. The contact surface of the geomembrane composite with non-woven and the supporting material should be leveled to prevent the film from being punctured and losing its impermeability. Otherwise, a fine-grained cushion should be provided to protect the film from damage.
2. Usually in corners and deformed areas, the joint length should be as short as possible. Except for special requirements, on slopes with a slope greater than 1: 6, within the range of 1.5 meters from the top slope or stress concentration area, as far as possible no welding seam is provided.
3. The connection of the geomembrane composite with non-woven itself. The connection methods of the impermeable film can be summarized into three types, namely the bonding method, the welding method and the vulcanization method, which are selected according to the different raw materials of the impervious film. The impermeability of all joints should be checked to prevent leaks due to poor joint connections.
