Product Description
Blow Molded Geomembrane
Blow molded geomembrane, produced by Dezhou Sentai Environmental Technology Company Limited, is a high-density polyethylene (HDPE) anti-seepage material designed to meet various project requirements. The production process involves careful steps to ensure quality and performance:
- Ingredients: High-density polyethylene raw materials with additives for improved antioxidant and UV resistance properties.
- Melting: Raw materials melted through an extruder to form molten plastic.
- Blow Molding: Molten plastic blown into a thin film shape through a blow molding machine head.
- Cooling: Blown film gradually cooled to room temperature for easier processing.
- Traction: Cooled film pulled through a traction device to achieve required thickness.
- Cutting: Geomembrane cut to specified length and width according to design specifications.
- Inspection: Quality inspection conducted on thickness, strength, toughness, and oxidation resistance.
- Packaging: Qualified geomembranes packaged for storage and transportation.
The key to producing high-quality blow molded geomembrane lies in the blow molding process, which directly impacts anti-seepage performance, strength, toughness, and weather resistance. Different production standards result in varying performance and price levels, so selecting the appropriate geomembrane based on specific needs is crucial.

Installation Instructions
Geomembrane Installation Guide
Geomembrane, a crucial geosynthetic material, is widely used in geotechnical and civil engineering projects. Its exceptional anti-seepage, corrosion resistance, deformation adaptability, and frost resistance make it indispensable. Here is a detailed guide on installing geomembranes:
Installation Steps:
Preparation Work:
- Ensure the construction site meets requirements and is debris-free.
- Avoid dragging or hard pulling geomembranes during transportation.
Measurement and Cropping:
- Accurately measure the laying area before cutting the geomembrane.
- Leave a 1.5% margin for local sinking and stretching.
Laying:
- Keep geomembranes flat and tightly pressed during laying.
- Ensure a slightly loose laying to prevent bubbles.
Joint Treatment:
- Stagger longitudinal joints by at least 1 meter from each other.
- Overlap width between membranes should be at least 10 centimeters.
Fixation and Protection:
- Press geotextile membrane with sandbags to prevent movement.
- Avoid sharp objects piercing the geomembrane.
Welding:
- Use hot melt welding or special adhesive bonding for welding.
- Adjust temperature and speed for firm welding.
Inspection and Backfilling:
- Conduct quality inspection after laying and splicing.
- Backfill only after ensuring no damages or leaks.
Notes:
- Ensure cleanliness of the construction site.
- Avoid damaging geomembranes during transportation.
- Take protective measures on cloudy or rainy days.
- Strengthen labor protection measures for employees.
Strictly follow construction specifications for each step from base treatment to backfilling to ensure project quality and durability. Pay attention to environmental and safety protection for smooth construction progress.
