Common Pond Leak Causes – Why Is My Pond Leaking?
Pond leaks can develop for many reasons. The most common causes we see in Devon and Cornwall include:
- Poor pond liner installation – liners stretched too tight or unsupported can split under pressure.
- Punctured liners – from falling debris, animal damage, or sharp stones beneath the liner.
- Cracked concrete ponds or waterfalls – common in older ponds where concrete perishes with age.
- Leaking pond pipework – brittle hoses and fittings can fail over time.
- Plant growth issues – marginal plants taking root outside the pond can create escape routes for water.
- Evaporation – especially during hot South West summers, though usually less than 2–3 cm a week.

Pond liner Replacement Devon and Cornwall
If your pond liner has reached the end of its life or was poorly installed, a full replacement can transform the pond’s performance and appearance. At Sasaquatics, we provide professional pond liner replacement across Devon, offering both traditional and eco-friendly materials to suit every site.
We carefully remove the old liner, prepare and level the pond base, and install a new heavy-duty rubber, PVC, or EPDM liner with protective underlay to prevent future leaks. For natural and wildlife ponds, we can also use clay sealing or a hybrid system that blends modern waterproofing with natural materials for a more sustainable solution.
Whether you’re in Exeter, Dartmoor, Totnes, or North Devon, our experienced team ensures every liner replacement is watertight, long-lasting, and ready to support healthy pond life for years to come.
Concrete Pond Repair & Sealing
Concrete ponds were popular before flexible liners, but cracks and corrosion are common over time. We can:
- Repair damaged concrete with new render
- Apply fibreglass or G4 polyurethane sealants for long-term waterproofing
- Advise on natural sealing methods (e.g. bentonite clay) for wildlife ponds in Devon and Cornwall
Clay & Natural Pond Repair – South West England Wildlife-Safe Materials
For large wildlife or farm ponds, we use natural materials such as Geosynthetic Clay Liners (GCLs) for installations and bentonite clay for clay and natural pond repair South West projects. This eco-friendly method helps restore water retention while supporting local biodiversity.
This is particularly relevant for wildlife ponds, farm reservoirs, and rewilding projects across Devon and Cornwall.
Pond Pipework & Waterfall Repairs
- Leaking pipes and fittings – replaced with heavy-duty pond hose or solid PVC for longer lifespan.
- Waterfall leaks – cracked concrete or waste build-up diverting water flow can be resolved through resealing and regular maintenance.

Pond Repair & Leak Detection – Frequently Asked Questions
How do I know if my pond is leaking?
If your water level drops more than 2–3 cm per week, even in cool weather, you likely have a leak. Common causes include punctured liners, cracked concrete, or leaking pipework. We can run simple tests to confirm and pinpoint the leak before recommending repair options.
Can you repair both liner and fibreglass ponds?
Yes — we work with rubber, PVC, and EPDM liners, as well as fibreglass and concrete ponds. Depending on the issue, we can patch, reseal, or fully replace the liner to give a long-term, watertight result.
Do you offer natural or wildlife-friendly repair methods?
Absolutely. Where suitable, we use bentonite clay and other natural materials for resealing ponds to maintain wildlife safety and ecological balance — ideal for natural or rewilded ponds.
