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. Quality Assurance and Testing

We fully recognize that seepage control projects are critical to ecological safety; therefore, we have established a comprehensive quality control system that spans the entire product lifecycle:

Raw Material Control: We utilize only 100% virgin LLDPE resin from globally renowned brands, strictly avoiding the use of any recycled materials.

In-line Monitoring: Our production lines are equipped with fully automated computerized thickness gauges and defect detection systems to ensure uniform and consistent thickness in every roll of geomembrane produced.

Laboratory Testing: In strict compliance with ASTM GRI-GM17 standards, we conduct batch-wise sampling tests to verify tensile strength, elongation at break, tear resistance, puncture resistance, and carbon black content, providing an official Certificate of Analysis (COA) for every batch.

6. Installation and Seam Treatment (Overview)

Professional installation and high-quality welding are the keys to the success of any seepage control project:

Subgrade Preparation: Prior to laying, the subgrade must be thoroughly cleared, ensuring it is level, compacted, and free of sharp stones, tree roots, or other debris that could puncture the geomembrane.

Anchor Trench Construction: Anchor trenches are excavated in accordance with design specifications to securely anchor the edges of the geomembrane, preventing slippage.

Thermal Welding: For large-area seams, we employ dual-track hot wedge welding machines to create double seams featuring an internal air channel for subsequent air pressure testing; for intricate details, corners, and repairs, single-track extrusion welding is utilized.

Quality Acceptance: Upon completion of welding, all seams undergo a 100% airtightness inspection using non-destructive testing methods (such as air pressure tests and vacuum box tests) to ensure a completely leak-proof seal.
