Leaking wildlife pond restoration
A failing liner, exposed edges and over-dominant planting were replaced with a deeper, better-shaped pond designed to hold water and mature naturally.
Repairing the cause, not disguising the symptom
The pond was stripped back, deepened, relined and rebuilt around stronger habitat structure.
Project overview
From unreliable and overgrown to settled and wildlife-rich
This Cornwall pond was losing water through a failing liner. Dense irises had taken over much of the available habitat, while shallow levels and visible liner edges left the pond looking unfinished and made long-term management difficult.
The brief was not simply to patch the leak. It was to rebuild the pond with useful depth, dependable water retention, stronger planting zones and a natural connection to the garden.

The leak was only one part of the problem
The existing pond needed a proportionate full rebuild rather than another temporary repair.
- Failed liner and unreliable water level
- Exposed liner edges weakening the natural appearance
- Irises dominating the margins and reducing planting variety
- Insufficient depth and poorly defined planting shelves
Construction approach
Strip back, reshape, retain what works
The pond was dismantled carefully so useful plants and materials could be retained. The profile was then rebuilt around better water depth, stable edges and practical planting zones.
More useful depth
Additional excavation created a more stable volume of water and clearer shelves for aquatic planting.
Protected EPDM liner
Protective underlay and a robust EPDM liner created a dependable water-retaining structure.
Natural slate structure
Around eight tonnes of slate formed planted beds and concealed the pond edge naturally.
Balanced planting
Useful plants were divided and replanted, with lilies and additional species added for shade and habitat.
The result
A pond designed to improve with age
The finished pond holds water reliably, offers more varied habitat and sits more naturally within the garden. As the planting established, lilies spread across the surface and the slate margins softened into the surrounding landscape.
- Dependable new liner system
- Greater depth and more useful planting zones
- Natural slate concealing and protecting the edges
- More varied habitat for amphibians, invertebrates and birds
- A clearer, more manageable long-term structure
Client response
The finished pond became part of daily garden life
“The finished article is a vast improvement. Even the cat has claimed the stepping stone as its favourite lookout!”
