What is the thickness of the Geomembrane?

January 24, 2022 | Geomembrane, Insights

Geomembrane is a plastic construction material product, which is waterproof, dense, used for drainage control projects to have an impermeable containment or barrier.

Geomembrane is one sort of geosynthetics product, with excellent Geomembrane properties and a competitive price advantage. It is used in various industries, water management, oil gas, environment, aquaculture, agriculture.

Ocean Global Geomembrane is made of polyethylene resin at the special formula; our products include HDPE Geomembrane, LLDPE Geomembrane, PVC Geomembrane, EDPM Geomembrane, RPP Geomembrane and TRP Geomembrane, all the products use 100% stainless material, no recycled secondary material.

HDPE Geomembrane refers to rich density polyethylene film used in civil anti-seepage projects. The thickness of the HDPE Geomembrane used in anti-seepage and waterproof projects ranks from 0.5mm to 3.0mm. The thickness may be 0.75mm, 1.0mm, 1.25mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm, 3.5mm, etc. apply hot-melt welding equipment for joint processing.

The thickness of the anti-seepage Geomembrane is usually designed during the engineering design. There are many aspects considered in the design: local environment, external factors, water depth, etc. The design thickness of the Geomembrane is also similar to the material and form of the soil. For example, the longer the diameter and angularity of the soil particles of sandy soil, the greater the thickness required.

The thickness of the Geomembrane opted for a different application field is also different. There are many used fields, such as municipal environmental protection field landfills, especially liquid waste, which has fluidity and extravasations and is simple to spread and difficult to control and handle. Now, Geomembrane can be used to solve this problem, generally, 1.5mm or 2mm thick Geomembrane is used in landfills.

Certainly, when Geomembrane is used in different directions in the landfill, the thickness of the Geomembrane is different, as a substrate for anti-seepage, side slope anti-seepage, and closure coverage. The categories of films used in different orientations are different, such as smooth surfaces for substrates and rough surfaces for slopes.

Farming Field

Geomembranes are used in the field of tray agriculture. As water seepage often occurs in diversion ditches, geomembranes can be used now to protect the extravasations of irrigation water and improve efficiency and longevity. Also, there are tray agriculture fish ponds and shrimp ponds. Geomembranes with a thickness of 0.75 mm and 1 mm are used.

Petrochemical Industry

The durability, acid resistance, alkali resistance, and chemical resistance of Geomembrane make it very popular in the petrochemical industry. It can be applied for anti-seepage in chemical sewage plants and oil refining sewage tanks to avoid chemical corrosive liquids and petroleum waste liquids. For diffusion and extravasations, these projects generally use Geomembrane with a thickness of 1.5mm, 2mm, or 2.5mm.

In addition, in the choice of thickness, there are many other aspects, such as landfill topography, soil quality, anti-seepage materials, anti-seepage requirements, and so on. How to select the thickness of Geomembrane in anti-seepage engineering? There is no doubt that the thicker the Geomembrane, but at the same time the cost will expand. The thinner the thickness, despite the cost can be reduced; it cannot meet the needs of the project.

Therefore, choosing a suitable thickness of Geomembrane can not only meet engineering needs but also complete the purpose of reducing costs. The thickness should be chosen and customized according to the engineering requirements of the Geomembrane. The thickness of the Geomembrane is generally not less than 0.5mm.

In the actual operation of the project, it is suggested to entrust the relevant testing center to test the materials to check whether the quality of the Geomembrane produced by the manufacturer is decent and to provide a basis for selecting safe, reliable, and economical materials. The application environment of Geomembrane is buried in the ground all year round, so it is required to have good anti-aging and anti-decomposition ability and can withstand the piercing of plant roots. For Geomembrane working in a complex water environment, it should further have good acid and alkali resistance.
