Geomembrane Case Study: HDPE Geomembrane Solution for a Gold Mine in Geita, Tanzania - Case Study

After comparing several geomembrane suppliers, the client ultimately chose EarthShield Geosynthetics for three key reasons:

1. Extensive mining experience – EarthShield has completed multiple geomembrane projects for heap leach pads and tailings ponds in East Africa.
2. Reliable quality – Our HDPE geomembranes are made from 100% virgin resin, offering high UV resistance and a long service life.
3. Fast local delivery – Thanks to our warehouse in Tanzania, materials can be delivered to site within one day, saving significant time and import costs.

EarthShield Geosynthetics provided the following for this project:
Product: 1.5mm HDPE geomembrane (smooth and textured)
Quantity: 65,000 square meters
Application: Heap leach pads, pregnant liquid ponds, process water ponds
Installation: On-site installation was guided by EarthShield technicians. EarthShield also provided online welding training to the client’s local contractor to ensure secure joints and a leak-free installation. During the installation process, our technical team provided online training and on-site weld inspection support.

Zero leakage during leaching operations
Stable performance even under continuous UV exposure
Reduced chemical losses and improved environmental compliance
The project has been operating safely for over 18 months, and the client has placed an order for an additional 130,000 square meters of geomembrane for the expansion phase.

“We are very satisfied with EarthShield’s geomembrane quality and quick delivery service. Their technical support made our project installation smooth and efficient. We highly recommend EarthShield as a trusted geomembrane supplier for mining projects in Africa.”
—Project Manager, Geita Gold Mining Company

1. Reliable anti-leakage performance: High-density polyethylene (HDPE) geomembrane provides an anti-seepage barrier, preventing toxic solutions from seeping into the soil and groundwater. 2. Excellent Chemical Resistance
   EarthShield high-density polyethylene (HDPE) geomembrane is made from 100% virgin polyethylene resin, offering strong resistance to acids, alkalis, and solvents, ensuring long-term chemical stability.
2. UV and Weather Resistance
   Mining projects in Africa (such as Tanzania, Ghana, and South Africa) are exposed to intense sunlight and high temperatures. EarthShield geomembrane is treated with a carbon black additive for UV resistance, ensuring a service life of up to 30 years even in extreme outdoor conditions.
3. Cost-effective and Eco-Friendly Solution: Compared to traditional clay or concrete lining systems, geomembranes offer lower costs, faster installation, and improved sealing performance.
4. High Tensile and Puncture Resistance: Mining sites have uneven surfaces, and EarthShield geomembranes offer excellent puncture and tear resistance, preventing damage to the lining during stone laying, solution flow, or mechanical operations. 6. Easy Installation and Seam Welding: EarthShield provides on-site guidance from professional welding technicians, ensuring efficient welding and secure, leak-free seams.
5. Localized Support and Faster Delivery: EarthShield’s Tanzanian warehouse allows customers to receive geomembranes within 1-3 days, significantly improving project efficiency.
