Apply Waterfall Foam

What happens here

Use black waterfall foam to fill any significant gaps or crevices between the rocks in your waterfall. This foam's primary purpose is to direct the water flow over the rocks, preventing it from seeping underneath and getting lost. Ensure the foam is applied in layers and allowed to expand, creating a watertight seal that guides the water visually. The black color helps it blend naturally with the rocks and shadows, making it less noticeable.

Goal: Optimize water flow over rocks for visual appeal
