Ponds & Water Features

Correctly built water features that stay watertight and easy to maintain

A pond or water feature that leaks, silts up, or needs constant intervention to keep clean usually points back to how it was built rather than bad luck — correct liner installation, pump sizing and edge detailing at the construction stage are what determine whether a water feature is a pleasure or a chore.

Ponds are typically formed using a flexible butyl liner over a carefully shaped and protected excavation, since sharp stones or roots left under the liner are one of the most common causes of a slow, hard-to-trace leak developing months or years after installation — proper underlay and careful excavation at the start avoids this entirely. Getting the shape right matters too: planting shelves at different depths allow marginal plants to be positioned correctly, and a deeper central zone helps maintain more stable water temperature and gives fish, where included, somewhere to retreat to. Pumps and filtration, where the feature includes moving water or is stocked with fish, need sizing correctly to the pond's volume — undersized filtration struggles to keep water clear, while an oversized pump can create currents that stress fish or disturb planting. Edge detailing is often the difference between a pond that looks intentional and one that looks unfinished: liner needs concealing neatly at the water's edge using stone, planting or turf, since visible liner at the perimeter is one of the most common giveaways of a poorly finished installation. Whether it's a full wildlife pond, a smaller formal water feature, or a simple bubbling water feature without open standing water, the same principle applies — get the groundwork and liner installation right, and the feature stays low-maintenance for years.
