With the development of the economy, the Thai government has become more stringent in environmental protection. All sewage treatment tanks in the factory are required to be lined with geomembrane tanks to prevent leakage of sewage and damage the environment. In order to ensure the quality of the heavy geomembrane, we have sent samples of different thicknesses to customers. After testing, our geomembrane meets the ASTM GRI GM13 standard. The customer chose our 100% virgin material geomembrane according to their needs. The thickness is 1.5mm and the total area of the project is 30000sqm.
