膨润土防水毯是-种新型土工合成材料,它是由-层粘土或其它低渗透性矿物材料外覆土工织物或防渗漏土工膜,使用抽筋或缝合线的技术成的优质生态景观组合防渗漏装修材料,会按照工作须得,还能够 在防渗毯上粘覆HDPE膜,以适合特有的环境的需用,达成更多自然的回填成效。
Geosynthetic Clay Liners are high performance needle punched environmental reinforced composites which combine two durable geotextile outer layers with a uniform core of natural sodium bentonite clay to form a hydraulic barrier. For diferent projects,it can combine HDPE liner for better waterproof.
膨润土防水涂料毯广泛性用于废料垃圾处理厂的,开采,水渠,大堤,河湖等回填工业。Geosythetic Clay Liners are widely used in waste landfill capping and cutoff walls to contain pollution,mining base seals, canal and dam liners, lakes and other waterproofing projects.
