Pond Liners – Eco-Friendly Water Solutions
At Rainbow Tarps and Linings, we craft premium pond liners for housing estates and individual property owners that protect South Africa’s aquatic ecosystems while creating local jobs and reducing waste through recycled and virgin liner options. A fully integrated pond liner system includes a pre-liner geosynthetic membrane, a waterproof liner and a UV shield.
Premium Pond Liners for Every Application
Our nylon-reinforced PVC liners combine flexibility with industrial strength:
- ✅ Fish & wildlife safe – non-toxic for koi, ducks and aquatic life.
- ✅ Contour-hugging flexibility – adapts to any pond shape/depth.
- ✅ Eco-conscious options – available in recycled/upcycled PVC.
- ✅ Commercial-grade durability – same quality as mine/farm dam liners.
1. Base Protection: Pre-Liner / Geotextile
Essential for rocky or uneven surfaces, protecting the liner from beneath against punctures or surface damage during periodic cleaning.
- 320 mic PVC mesh: upcycled open-weave protection, cost-effective alternative to bidum.
- 400 mic reinforced PVC: upcycled standard-duty underlayment.
⚠️ Perforated/porous material – cannot be used as a waterproof liner.

3. Edge Protection: UV Shield
Extends liner lifespan and prevents sun damage in fluctuating water-level areas above the water line.
