Waterproof And Anti-Seepage HDPE Smooth Geomembrane For Civil
Engineering Projects
Product Introduction
Smooth geomembrane, also known as smooth geomembrane, is a widely
used waterproof barrier geosynthetic material. The material is
based on high molecular polymer, adding carbon black, antioxidant,
anti-aging agent, ultraviolet absorber and color masterbatch and
other auxiliary materials through special formula.
Product Properties
1. Low permeability: Smooth geomembrane has extremely low
permeability, which can effectively prevent the passage of water
and pollutants.
2. Chemical and ultraviolet resistance: Excellent chemical and
ultraviolet resistance make the material resistant to various
chemical substances and prolonged exposure to sunlight.
3. High cost performance: Compared with other similar products,
smooth geomemofilm has a higher cost performance, is the first
choice for civil engineering seepage prevention materials.
4. Strong adaptability: wide temperature adaptability, can be used
in extreme weather conditions.
Product Application
1. Water conservancy and environmental protection: applied to the
anti-seepage reinforcement of river dikes, lake DAMS, tailings
DAMS, etc.
2. Municipal engineering: such as subway, building underground
engineering, planting roof anti-seepage lining.
3. Aquaculture: Suitable for seawater, freshwater fish and shrimp
farms.
4. Garden engineering: It can be used for waterproofing and
moisture-proof of river, reservoir, artificial lake, etc.
5. Salt industry: salt field crystallization tank, halogen tank
cover and other occasions.
6. Transportation infrastructure: waterproof layer of highway,
railway foundation, etc.
7. Petrochemical industry: chemical plants, refineries, oil storage
tank anti-seepage lining, etc.
8. Mining engineering: the bottom lining of washing pool, pile
leaching pool, etc.
