Geomembrane for Construction Engineering
Geomembrane is a black plastic film with impermeable and isolated properties, also known as impermeable film. It is mainly made of high molecular polymer such as high density polyethylene (HDPE), so it is also often called HDPE geomembrane or HDPE impermeable film.
Geomembrane has various applications in the field of construction engineering, serving as an essential material for various purposes. Here are the key uses of geomembrane in construction engineering:
Waterproofing: Geomembrane is extensively used for waterproofing in structures such as tunnels, dams, underground projects, and sewage treatment plants. It effectively prevents the penetration of water, chemicals, and other fluids, ensuring the structural integrity and durability of the buildings.
Underground Engineering: In underground construction projects, geomembrane acts as a barrier against groundwater infiltration, protecting the underground structures from moisture damage. For instance, the Shanghai Expo Center commercial building in Pudong New Area, located in a core business district, utilized high-density polyethylene geomembrane to control groundwater seepage, enhancing the reliability and safety of the building.
Containment Structures: Geomembrane is suitable for use in the construction of containment structures, such as reservoirs and ponds. Its excellent impermeability ensures that the stored fluids do not leak into the surrounding environment, safeguarding the safety of the stored water or chemicals.
Environmental Protection: In environmental protection projects, geomembrane is often used to cover landfills, wastewater treatment lagoons, and other facilities to prevent leakage and contamination of the surrounding soil and groundwater.
In summary, geomembrane plays a crucial role in construction engineering, providing waterproofing, containment, and environmental protection solutions for various structures and projects. Its wide range of applications and superior performance make it an indispensable material in modern construction.

Applications:
Underground Structures:
Tunnels: Geomembrane effectively prevents soil and water from infiltrating the tunnel, ensuring the structural integrity and safety of the tunnel.
Dams and Embankments: Its impermeability characteristics prevent water from seeping through the dam body, thus maintaining the stability of the dam.
Underground Facilities: Such as subway stations, underground garages, and underground warehouses. Geomembrane acts as a waterproof barrier, protecting the structures from moisture damage.
Waterproofing Systems:
Roofs: Geomembrane is used as a waterproof layer on roofs, preventing water from infiltrating the building.
Basements: It provides a waterproof barrier for basements, protecting the structure from groundwater infiltration.
Swimming Pools: Geomembrane ensures that water stays within the pool, preventing leakage and ensuring the proper functioning of the pool.
Environmental Protection Facilities:
Landfills: Geomembrane covers the landfill, preventing the leakage of waste and contaminants into the surrounding soil and groundwater.
Wastewater Treatment Plants: It acts as a liner for various wastewater treatment facilities, ensuring the effective treatment of wastewater while preventing leakage.
Other Applications:
Geomembrane is also used in the construction of reservoirs, ponds, and other water storage facilities. Its impermeability ensures that the stored water remains clean and free from contamination.
In summary, geomembrane's applications in construction engineering are diverse and crucial. Its waterproofing, impermeability, and environmental protection properties make it an indispensable material in various projects, ranging from underground structures to environmental protection facilities.
