The thickness of geomembrane should be selected based on comprehensive considerations such as specific engineering requirements, soil conditions, geographical environment, usage functions, and economic practicality.

How to choose the thickness of geomembrane?

The thickness selection of geomembranes is a complex process that requires consideration of multiple factors, including specific engineering requirements, soil conditions, geographical environment, usage functions, and economic practicality. The following is a detailed analysis of the thickness selection of geomembranes:
1. Common thickness range
The thickness range of geomembranes is generally between 0.2mm and 3.0mm. Common geomembrane thickness specifications include 0.5mm, 0.75mm, 1.0mm, 1.2mm, 1.5mm, 1.8mm, 2.0mm, etc.
2. Thickness selection in different projects
Aquaculture: Generally, geomembranes with a thickness of 0.3mm to 0.8mm are used, and thicker ones can be selected for special needs. For most aquaculture scenarios, it is recommended to use geomembranes of about 0.5mm, which can meet the anti-seepage requirements and have good economy and practicality.
Landfills: Geomembranes with a thickness of 1.5mm to 2.0mm are usually used to ensure anti-seepage performance and durability.
Artificial lake: Generally, geomembranes with a thickness of 0.5mm to 1.0mm are used, which are selected according to the size and depth of the lake and the anti-seepage requirements.
Reservoir: The thickness is generally between 0.6mm and 1.5mm, depending on the scale of the pool and the anti-seepage requirements.
Biogas pool: The thickness is generally 1.0mm to 2.0mm to meet the pressure and anti-seepage requirements of biogas.
Waste yard, waste residue treatment, tailings pond, etc.: Geomembranes with a thickness of 1.2mm to 3.0mm are usually used to ensure safety and environmental protection.
Roof garden: Generally, geomembranes with a thickness of 1.5mm or 2.0mm are used to withstand the load and waterproofing requirements of the roof.
3. Other factors to consider when selecting
Soil conditions: If the permeability of the soil is high, then a thicker geomembrane needs to be selected to ensure the anti-seepage effect.
Project requirements: If the project requires high waterproof performance, then a thicker geomembrane needs to be selected.
Geographical environment: If the project is in a high altitude, cold, humid environment, etc., it is necessary to select a suitable geomembrane to ensure service life. For example, in cold areas, geomembranes with good antifreeze properties should be selected.
Material properties: Geomembranes of different materials have different physical and chemical properties, such as tensile strength, elongation, aging resistance, etc. When choosing the thickness, these performance factors need to be considered comprehensively.
