What Is a 0.5mm Dam Liner?
A 0.5mm dam liner is a geomembrane sheet typically made of materials like HDPE (High-Density Polyethylene), PVC, or EPDM. It serves as a waterproof barrier for reservoirs, ponds, and canals, preventing water leakage and protecting the soil.
Key Features:
- 🔹 Material Composition: Often made of HDPE, known for its durability.
- 🔹 Flexibility: Lightweight and easy to handle during installation.
- 🔹 Thickness: At just 0.5mm, it’s among the thinnest available for large-scale use.

Chemical Resistance of 0.5mm Dam Liners
The ability of a dam liner to resist chemical degradation is crucial, especially in reservoirs that might hold chemically treated water.
Chemical Resistance Chart:
| Chemical | Resistance Level | Notes |
|---|---|---|
| Acidic water (pH 3-6) | High | Suitable for agricultural reservoirs. |
| Alkaline water (pH 8-11) | Medium | Moderate resistance; may require thicker liners for long-term use. |
| Hydrocarbons | Low | Not ideal for industrial wastewater. |
Performance Insights:
- Agricultural Reservoirs: Ideal for holding irrigation water mixed with fertilizers.
- Industrial Use: May degrade faster when exposed to harsh chemicals, compared to 1mm or thicker liners.
Pro Tip: Use double-liner systems for chemically active reservoirs.
Cost and Availability
Cost and availability often determine whether a 0.5mm dam liner is the right choice for your project.
Cost Analysis:
| Thickness | Price Range (per m²) | Suitability |
|---|---|---|
| 0.5mm | $2-$4 | Small to medium reservoirs. |
| 1.0mm | $5-$8 | Large reservoirs with higher pressure. |
| 1.5mm | $8-$12 | Industrial and chemical reservoirs. |
Availability:
- Widely available in local hardware stores and online marketplaces.
- Custom orders possible for larger installations.
Tip: Check local suppliers for bulk discounts or installation packages. 💵
Comparison: 0.5mm vs Other Thicknesses
| Feature | 0.5mm Liner | 1.0mm Liner | 1.5mm Liner |
|---|---|---|---|
| Durability | Moderate | High | Very High |
| Installation Ease | Easy | Moderate | Challenging |
| Chemical Resistance | Medium | High | Very High |
| Cost | Low | Medium | High |
When to Choose 0.5mm:
- If cost is a major factor.
- For reservoirs with minimal chemical exposure.
- For temporary installations.
Case Studies
Case Study 1: Agricultural Reservoir in Kenya
- Project: A 10,000m³ irrigation reservoir.
- Solution: 0.5mm HDPE liner.
- Outcome: Lasted 5 years with minimal maintenance; only minor repairs were needed.
Case Study 2: Industrial Cooling Reservoir in South Africa
- Project: A 20,000m³ industrial reservoir.
- Solution: Upgraded from 0.5mm to 1.0mm liner after chemical degradation.
- Lesson: Chemical exposure requires higher thickness.
Statistics on Dam Liner Failures
- Failure Rate: Approximately 15% of 0.5mm liners fail within 3 years due to mechanical stress.
- Primary Causes:
- Punctures during installation (35%).
- Chemical degradation (25%).

FAQs
1. Is 0.5mm thick enough for large reservoirs?
It depends on the reservoir’s use. For small agricultural reservoirs, it is often sufficient. For large reservoirs with chemical exposure, opt for a thicker liner.
2. How long does a 0.5mm dam liner last?
Typically 5-8 years under optimal conditions. Harsh environments may reduce this lifespan.
3. Can 0.5mm liners handle high water pressure?
They can handle moderate pressure but may deform or tear in deeper reservoirs exceeding 3 meters in depth.
