A Must for Water Gardens, Ponds & Pond Free Waterfall Installations! Waterfall foam helps you fully enjoy the visual and sound effects of splashing, flowing water!

We all know that water rushes to the lowest place; waterfall foam prevents your waterfall and stream from disappearing beneath the rocks and stones in your feature. Black Foam fills gaps and voids, forcing the water to flow over rocks and stones, giving you the full effect you're looking for!

• Seal gaps and fill voids between streambed & waterfall rocks and stones


• Stabilizes rockwork in Koi ponds, water gardens and pondless waterfalls


• Moving water travels over (not under!) rocks and stones for dramatic visual effect!
