Introduction to Smooth Surface Geotechnical Membrane

Smooth geomembrane, also known as smooth geosynthetic membrane, is a waterproof and barrier-type geosynthetic material made from high molecular polymer as the basic raw material. It uses high-quality primary high-density polyethylene (HDPE) as the impervious base material, adding a certain amount of carbon black, antioxidants, anti-aging agents, ultraviolet absorbers and color masterbatches as additives in the production process. Through highly automated geomembrane equipment and three-layer co-extrusion blow molding technology, it is mass-produced and refined.

Features

The smooth surface geomembrane has the following characteristics:

1. Extremely Low Permeability: Effectively prevents moisture penetration, suitable for projects with high requirements for water resistance.

2. Outstanding chemical resistance: Able to resist the erosion of various chemicals, suitable for complex environments such as environmental protection and municipal engineering.

3. Ultraviolet Resistance : Extends the lifespan of materials in outdoor environments.

4. Wide Temperature Adaptability: Can be used under extreme temperature conditions, ranging from as low as -70°C to as high as 110°C.

5. Environmental Friendliness: High-quality virgin plastic and carbon black particles contain no preservatives, and do not pollute water or soil.

Application

The smooth surface geomembrane is widely used in various fields due to its excellent performance.

1. Hydraulic Engineering: Such as river channel management, reservoir seepage prevention, etc., to improve the waterproof performance and stability of the project.

2. Environmental Engineering Projects: Such as landfills and wastewater treatment plants, which reduce pollution to the environment.

3. Municipal Engineering: Such as the basic imperviousness of roads and bridges.

4. Aquaculture: Used for waterproofing fish ponds, shrimp ponds, and other aquaculture pools.

5. Garden Landscape: Used for waterproofing landscape ponds, artificial lakes, etc.

Advantages

The smooth surface geomembrane has the following advantages compared to traditional waterproof materials:

1. Environmental Friendliness: Does not contain harmful substances and does not pollute the environment.

2. Reusability: Simply replace the surface layer to save resources and reduce waste.

3. Wide Application: Suitable for various types of waterproof projects.

4. Ultraviolet Resistance : Protects materials from damage by ultraviolet rays.

5. Good stability: It is not easy to deform or break under physical forces.

To sum up, the smooth surface geomembrane has become one of the preferred materials for impervious in civil engineering projects due to its excellent performance and wide range of applications.
