Get Waterproofing QuotesWhat It Covers
- Liners. EPDM, PVC or HDPE liners for new or failed ponds.
- Coatings. Fish-safe coatings for concrete and brick ponds.
- Edges and rocks. Sealing the edge where water wicks or overflows out.
- Pumps and pipes. Sealing penetrations for pumps, filters and returns.
- Water features. Waterfalls, streams and fountains.
Signs of a Leak
- Water level drops. More than normal evaporation, especially if it stops at the same level.
- Wet ground nearby. Soggy soil or plants around one side.
- Cracks. Visible cracks in concrete or plaster ponds.
- Liner damage. Punctures, shrinkage or folds pulled below the waterline.
A leak at the waterfall or filter can look like a pond leak. Testing with the pump off helps find the source.
Liner or Coating?
- Liner. Suits soil ponds, irregular shapes and badly cracked old ponds.
- Coating. Suits sound concrete or brick ponds with minor cracks.
- Fish safety. Any product in contact with fish water must be rated fish-safe and fully cured.

Get Waterproofing QuotesWhat Affects the Quote
- Size and depth. Liner area includes the sides and overlap, not just the surface.
- Liner or coating. Material choice and thickness set much of the cost.
- Fish and plants. Moving and holding fish and plants adds time.
- Rockwork. Removing and replacing rocks and edging adds labour.
How the Work Normally Runs
- Find the leak. Pump off, level checks and inspection of edges and features.
- Drain and relocate. Fish and plants are moved to holding tanks.
- Prepare. Debris, sharp stones and loose plaster are removed; underlay goes under liners.
- Waterproof. Liner fitted or coating applied and cured.
- Refill. The pond is refilled, water treated and fish returned.
Maintenance and Questions to Ask
- Keep edges high. Soil and plants over the liner edge wick water out.
- Check levels. Note water loss in hot weather to spot new leaks early.
- Ask. Is the coating or liner fish-safe, and how long must it cure?
- Ask. Who handles the fish while the pond is drained?
- Ask. What guarantee applies to the liner and the workmanship?
Pond Waterproofing FAQs
How do I know if my pond is leaking or just evaporating?
Switch off the pump and mark the level. If it drops much faster than a bucket of water next to it, there is probably a leak.
Can a pond be fixed without draining it?
Small edge or pipe leaks sometimes can. Liners and coatings need the pond drained.
Are pond coatings safe for koi?
Only products rated fish-safe, applied and cured as the manufacturer specifies.
How long does a pond liner last?
It depends on the material, UV exposure and installation. Ask each contractor for the expected life.
