Choose Dezhou Sentai Environmental Technology Company Limited's blow molded geomembrane for reliable and durable anti-seepage solutions.
Our blow molded geotextile, manufactured by Dezhou Sentai Environmental Technology Company Limited, is made using carefully selected high-density polyethylene raw materials. To enhance its properties, we incorporate additives such as carbon black, antioxidants, and UV absorbers.
The selected high-density polyethylene raw material is melted using an extruder, resulting in a molten plastic. This molten plastic is then blown into a thin film shape using our state-of-the-art blow molding machine. The blow molding process ensures the formation of a high-quality and uniform thin film.
After the blow molding process, the blown geosynthetic film is gradually cooled to room temperature through a cooling device, facilitating further processing. The cooled geotextile is then pulled through a traction device at a set speed and direction to achieve the desired thickness.
Following the traction process, the geomembrane is cut according to the design specifications, resulting in a specified length and width of geomembrane. We conduct thorough quality inspections on the produced geotextile, ensuring its thickness, strength, toughness, oxidation resistance, and other aspects meet our high standards. Only qualified geomembranes proceed to the next process.
Our blow molded geotextile offers exceptional durability and performance. It provides effective soil stabilization, erosion control, and filtration. With its high-quality and uniform thin film, it ensures reliable and long-lasting protection for various applications.

Geomembrane, an essential geosynthetic material, finds extensive application in geotechnical and civil engineering projects. Its remarkable properties, including excellent anti-seepage, corrosion resistance, deformation adaptability, and frost resistance, make it indispensable in various construction endeavors. In this guide, we will provide a detailed step-by-step installation process and important precautions for geomembranes.
Ensure that the construction site meets the necessary requirements, remove debris and dust, and ensure a flat and solid foundation. Avoid dragging or forcefully pulling the geomembranes during transportation and storage to prevent damage.
Accurately measure the dimensions of the laying area before cutting the geomembrane, and cut it according to the actual needs. Leave a margin of 1.5% during cutting to account for local sinking and stretching, avoiding excessive tightness.
Keep the geomembranes flat and tightly pressed from bottom to top, ensuring a secure fit between membranes and between membranes and the substrate. Ensure a slightly loose laying of the membrane to prevent the formation of bubbles at the bottom. Begin laying from the slope and progress towards the bottom of the field. On the slope, align the direction of the film parallel to the maximum slope line.
Stagger the longitudinal joints of adjacent frames by more than 1 meter and avoid placing them on the same horizontal line. Ensure that the longitudinal joint is at least 1.5 meters away from the foot of the dam or the bend, and place it on a flat surface. The overlap width between membranes should generally be no less than 10 centimeters.
After laying the geotextile membrane, press it with sandbags to prevent wind movement. Make detailed records and numbering for corners and deformed areas on a dedicated form. Avoid sharp objects that may pierce the geomembrane during the laying process.
Use hot melt welding or special adhesive bonding for welding geomembranes. Ensure that the two sides of the PE single film at the joint are flat, wrinkle-free, and overlap with a certain width before welding. Adjust the temperature and speed during welding to ensure a strong and secure weld.
Conduct a quality inspection after completing the laying and splicing of geomembranes. Backfilling operations should only be carried out after ensuring the absence of damages, bubbles, welding leaks, or any other issues.
In summary, the installation of geomembranes must strictly adhere to construction specifications. Each step, from base treatment, cutting, laying, jointing, to final fixation and backfilling, significantly impacts the quality and durability of the project. Additionally, environmental and safety protection measures should be prioritized to ensure smooth construction progress.
