Tailings seepage carries heavy metals and reagents; acidic (phosphogypsum) or alkaline (red mud) slurries attack liners; steep dam slopes slide, sharp tailings puncture, and closure must stay stable for decades.
Tailings Pond Lining: Tailings ponds: base 1.5-2.0mm smooth HDPE, dam slopes equal-thickness double-textured HDPE, 400-600 g/m² filament geotextile plus sand cushion below, composite drainage net above. For acidic/alkaline tailings verify chemical resistance and uprate to ≥1.5mm with higher weld sampling. Closure caps the crest cover and slope liner together with monitoring wells and displacement markers.

| Location | Recommended material | Reason |
|---|---|---|
| Base liner | 1.5-2.0mm smooth HDPE | Chemical resistance, low k |
| Slope liner | 1.5-2.0mm double-textured | Steep faces need friction |
| Cushion | 400-600 g/m² filament geotextile + sand | Sharp tailings protection |
| Drainage | Composite drainage net or gravel blinds | Seepage & groundwater conduction |
| Composite liner | GCL-OF double liner | High-grade containment |
| Closure cover | 1.0-1.5mm HDPE + drainage + vegetation | Long-term stability |
2023Tailings pond remediation: 1.5mm smooth HDPE on the basin, 1.5mm double-textured on dam slopes, 400 g/m² filament geotextile plus sand cushion, crest anchor trenches with berms, and groundwater monitoring wells.
View project details ›HDPE resists alkali far better than PVC; ≥1.5mm, double-textured on slopes, higher inspection rates.
HDPE ≥1.5mm, intercepting ditches around the yard, anchor trenches and berms on slopes.
Crest cap and slope liner built together, cover membrane ≥1.0mm, rainwater-shedding grades, groundwater and displacement monitoring.
