1. Tailings Storage Facilities (TSFs)

Typical TSF lining systems supplied and installed by Geosynthetics Africa include:

• 1.5mm–2.0mm HDPE primary liner

• Nonwoven geotextile protection (300–800 gsm)

• Leak detection geocomposites

• HDPE pipe boots and penetrations

• Anchor trench construction & detailing

• Spark testing / holiday detection QA/QC

Applications within a TSF:

• Basin lining

• Embankment containment

• Decant pond areas

• Finger drains & underdrain systems

• Return water channels

HDPE offers long-term UV stability, chemical resistance, and up to 50-year service in tailings environments.

2. Process Water Dams & Make-Up Water Reservoirs

Mining operations store significant volumes of process water, reagent water, and return water.
HDPE is the preferred containment liner for:

• Process water dams

• Clarified water ponds

• Reagent make-up reservoirs

• Fire water and emergency reservoirs

• Plant runoff containment

Our solutions include:

• 1.0–1.5mm HDPE liners

• Geotextile underlays

• Anchoring and perimeter trenching

• Outlet/inlet structures and fittings

• Full welding & seam QA/QC

3. Pollution Control Dams (PCDs)

PCDs require zero leakage tolerance, especially where hydrocarbons, workshop runoff, or chemically contaminated water may accumulate.

HDPE systems installed by Geosynthetics Africa include:

• 2.0mm HDPE primary liner

• Secondary containment options

• Leak detection layers

• Sumps & inspection points

• Heavy-duty geotextile protection

These systems ensure full environmental compliance for mining operations.

4. Heap Leach Pads

For gold, copper, cobalt, nickel, and rare-earth heap leaching:

• Textured HDPE for slope stability

• Chemical-resistant HDPE for aggressive leach solutions

• Subgrade preparation & geotextile cushioning

• Drainage geocomposites for solution extraction

HDPE liners are compatible with all leach chemistry including cyanide, sulfuric acid, and chloride solutions.

5. Leak Detection, QA/QC & Integrity Testing

To ensure quality and full containment, we provide:

• Electric Leak Location (ELL) surveys

• Spark/holiday detection

• Vacuum box testing

• Destructive seam sampling

• Full documentation and as-built reports
