PRODUCT DETAILS
1. Product Overview
The Perfect Balance of Flexibility and Durability. When your project involves complex curves, irregular shapes, or uneven subgrades, rigid liners just won't cut it. Our 0.75mm (30 mil) Smooth LLDPE Geomembrane Liner is engineered to solve this problem. Offering superior conformability compared to HDPE, this liner molds effortlessly to the contours of your pond or canal without stress cracking. It is the ideal choice for Koi ponds, landscape water features, and canal restoration, providing a robust barrier that is easy to install and safe for aquatic life.
2. Key Features
-
Ultimate Conformability: High malleability allows the liner to stretch and fold around tight corners, rocks, and pipe penetrations without the need for excessive cutting or welding.
-
Enhanced Puncture Resistance: At 0.75mm (30 mil), it offers a 50% increase in thickness over standard 0.5mm liners, providing critical protection against root penetration and rocky subgrades.
-
Fish & Plant Safe: Manufactured from virgin LLDPE resins. Free from plasticizers and harmful chemicals, creating a non-toxic environment for Koi, shrimp, and organic aquatic plants.
-
High Elongation (>800%): In the event of ground settling or seismic activity, this liner stretches rather than tears, maintaining its waterproof integrity.
-
UV & Weather Stable: Fortified with carbon black to resist UV degradation, ensuring a long service life even when exposed on pond banks or canal edges.
3. Detailed Application Scenarios
Garden Ponds & Water Features (Landscape)
For residential and commercial landscaping, aesthetics are key. The 0.75mm LLDPE Liner is pliable enough to create natural-looking pond edges and waterfalls. Its flexibility minimizes unsightly folds and wrinkles that can trap sludge and spoil the view.
Canal Lining & Restoration (Civil)
Restoring old, cracked concrete irrigation canals is challenging. Our LLDPE liner acts as a flexible bladder, sitting inside the old canal. Its ability to bridge cracks and adapt to the shifting concrete makes it a superior, cost-effective alternative to re-concreting.
Aquaponics & Biofloc Systems
Safety is paramount in food production. Our LLDPE liner provides a certified safe barrier for grow beds and fish tanks, ensuring no chemical leaching affects your harvest.
Golf Course Lakes
Large decorative lakes often have complicated geometries. LLDPE allows for rapid deployment and fewer field seams, reducing installation time and labor costs.

5. LLDPE vs. HDPE: Which one do you need?
-
Choose 0.75mm LLDPE if: You are building a creative garden pond, lining a cracked canal, or working in cold weather. You need a material that bends easily and handles uneven ground.
-
Choose HDPE if: You are building a massive, flat-bottomed sanitary landfill or a mining heap leach pad where chemical resistance is the only priority and the ground is perfectly compacted.
