Colored Sand Surface Superior Weather Resistance Building Stable & Durable Tunnel Linings
 
       Product Description     
 
 
 
    |  Product Name |  HDPE Waterproofing Membrane |  
  |  Material |  HDPE  |  
  |  Color |   White |  
  
      The HDPE waterproofing membrane is manufactured from a white polymer base material—either HDPE or TPO—and features an integrated pressure-sensitive adhesive along with a granular, weather-resistant top layer. It is specifically engineered to enhance installation efficiency and waterproofing reliability in below-ground applications.
 
         Advantages      
 
 
  - White sheet with non-recycled HDPE or TPO(pellets) as raw materials; 
  - Resistant to weather conditions, withstand up to 49 days of UV exposure, rain, dirt and contaminants, etc.
  - Good dimensional stability-- dimensional variation rate does not exceed 0.5%;
  - Resistant against impact and puncture, not easy to be destroyed during construction;
  - Effective overlapping can be realized in the water, free from wet jobsite conditions;
  - High resistance to chemicals such as acid, alkali and salt.
