Geotextile has exceptional drainage isolation, anti-seepage and strengthening properties, and filtration. Moreover, it has features like low weight, high tensile strength, permeability, heat resistance, and anti-freezing due to geotextile cloth and nonwoven geotextile. Geotextile is also used because it is highly resistant to corrosion.
Geomembrane makes use of plastic film, which is a famous anti-seepage material. It has a small specific gravity, robust elongation, malleability, resistance to corrosion, low-heat resistance, and average frost resistance. Both of these materials, geotextile, and geomembrane, can be used alone or in combination to attain strength.
Geomembrane is usually used in engineering-related constructions where seepage-proof material is required for properties like isolation, firm foundations, good drainage material and anti-cracking. Another major difference is that for anti-filtering purposes, geotextile is highly preferred, while geomembrane is utilized for seepage-proofing.
Geotextiles, just as its name implies, is made of nonwoven fabrics and mainly used to the consolidated subsoil. Geomembrane is made of high-density polyethylene, primarily for seepage-proofing. The combination of the two is composite geomembrane, which can be divided into one cloth one membrane and two cloths and one membrane, with the more reliable anti-seepage property. Woven geotextile is heavily used in Malaysia for soil stabilization.
