Pontec Pond Liner – 0.5mm Thick PVC – 15-Year Guarantee
Thickness matters when choosing a pond liner. Pontec pond liners are made from robust 0.5mm thick PVC – approximately 67% thicker than 0.3mm PVC liners. When comparing prices, check the thickness as well as the liner dimensions.
The flexible black PVC follows the contours of your pond, including shelves and planting areas, making it suitable for a variety of small and large ponds. Designed for a long service life, Pontec liners resist weathering and root growth and can be repaired using suitable PVC pond liner products.
Includes the Pontec quality promise: a 15-year guarantee, subject to the manufacturer's terms and conditions.
- 0.5mm thick PVC – approximately 67% thicker than 0.3mm PVC liners
- Flexible black liner for different pond shapes, shelves and planting areas
- Resistant to weathering and root growth

Choosing your pond liner size
Measure your pond's maximum length, maximum width and maximum depth. Your liner needs to accommodate the full depth and leave sufficient overlap around the edges to secure beneath your chosen pond edging.
Use our pond liner calculator below to help work out the size you need, then select an available sheet size that meets or exceeds both calculated dimensions.
Installation advice
Remove sharp stones, roots and other debris before installation. Use a suitable pond liner underlay beneath the liner to help protect against punctures. Resistance to root growth does not make the liner puncture-proof.
Please note: the dimensions selected are the liner sheet size, not the finished pond size.
You will need the approximate length, width, and depth in metres of your pond.
