Ponds and water features hold water continuously, so the waterproofing must suit immersion, the substrate and the intended finish. Corners, changes of plane, pipework, pumps and outlets interrupt the main surface and need compatible details. Planning those interfaces before the feature is built makes it easier to install and inspect a continuous system.
When a pond loses water, the membrane is only one possible cause. Fittings, plumbing, movement or an overflow detail may also be involved. Record the water-loss pattern and any past repairs before choosing a remedy. A suitable repair depends on the condition of the retained material and the source of the loss. See Waterseal’s water feature, pond and pool waterproofing service for the full scope.
Plan the details before immersion
Pond waterproofing must work with the prepared substrate, water exposure and final finish. Corners, outlets, pumps and decorative features create interfaces that need membrane continuity. Access for installation and maintenance should be considered before landscaping conceals the construction.
Unexplained water loss may involve fittings, plumbing, movement or the waterproofing itself. Record the water-loss pattern and any earlier repairs so an inspection can focus on the likely pathways. The repair method depends on the findings and compatibility with the retained system.
