Geotextiles and geomembrane fabric are mostly used in civic technique construction. There are a number of differences between these materials.
Many people though that they are similar because they are geotechnical materials as well as commonly used waterproof materials. Besides that, their name is quite similar too.
In fact, they are different items from various aspects. You will know further about those differences in the explanation below.
Performance and Usage Differences
What type of geosynthetics should a geomembrane fabric or geotextile choose in an earthwork project? Geomembranes are made of high-density polyethylene, which is mainly used to prevent seepage.
Meanwhile, geotextiles are made of non-woven fabrics, which are mainly used to strengthen foundations. Its impermeability depends primarily on the impermeability of the plastic film.
When you use them, usually use them together. They are divided into one fabric, one membrane, and two one-membrane fabrics that have stronger anti-seepage performance.
Geotextile is a kind of permeable geosynthetic material made of synthetic fiber by needling or weaving. It is widely used in highways, railways, water conservancy, large-scale construction, power plant ash dam construction, etc.
Geomembrane fabric is a plastic membrane, and geotextile is a fiber cloth geosynthetic material. A geomembrane is usually used to separate two different areas.
Differences in Nature
Geotextiles are one type of good geotechnical data. The design requirements of the geotextile permeability coefficient are more than 10 times that of the soil.
Therefore, in order to increase the front water table, it is possible to bring smaller-sized soil particles close to the geotextile into the geotextile under the influence of permeability.
This situation has gradually developed far from geotextiles and gradually formed a certain thickness of the upper layer composed of coarse soil particles. The particles in this layer are relatively coarse and the permeability coefficient is large.
However, it cannot prevent the fine movement of soil particles. When the filtering effect of geotextile is fully applied, a natural filter layer will form on the upstream side of the upper layer.
The fine soil particle content of the natural filter layer is more than that of the upper layer, and the water permeability is relatively low. That is why; it can block the movement of fine soil particles of the adjacent natural soil layer.
The Definition Between Two Materials
To know further about geomembrane fabric and its differences from geotextile, we can see it from the definition. Here is the further description that we may need to know.
1. Geomembrane Material
Geomembranes are a type of geosynthetic that is relatively impermeable. According to different raw materials, it can be divided into polymer and asphalt.
In order to meet the needs of different forces and deformations, there is a difference between unstrengthened and strengthened. Polymer membranes are produced in factories, while asphalt membranes are mostly produced in the field.
2. The Liner Part
What are geomembrane fabric liners made of? The polymers used to make this item are thermoplastics (PVC geomembrane), crystalline thermoplastics (HDPE geomembrane), thermoplastic elastomers (such as oxidized polyethylene), and rubber (such as neoprene), etc.
This product manufacturing is extrusion, calendering, or coating. Those processes can create a high-quality geomembrane fabric for various needs.
