Pondmax - Black Waterfall Foam – 330 ml (12 oz)

by OASE

Unwanted water loss and uneven flow are common issues in waterfalls and pond features.

Black Waterfall Foam is designed to fill gaps between rocks and hardscape, helping direct water where you want it while creating a natural-looking finish.

The black colour blends into rock work, making it far less visible than standard expanding foams.

What this is used for

Black Waterfall Foam is used in pond and water feature construction to control water flow and seal gaps.

  • Directing water over waterfalls instead of behind rocks
  • Filling voids between rocks and feature liners
  • Reducing water loss in pond and stream features
  • Improving the appearance of rock work in water features

What to check before you buy

  • Application area: Suitable for use in ponds, waterfalls, and decorative water features.
  • Colour: Black foam is designed to blend with rock work and shaded areas.
  • Cure time: Allow foam to fully cure before running the system.
  • Trimming: Excess foam can be trimmed once cured for a cleaner finish.

Important usage note

This product is used to shape and direct water flow, not as a structural adhesive.
