Waterfall Foam


This black polyurethane waterfall foam is ideal for filling joints and gaps between rocks and boulders maximizing the amount of water cascading over the waterfall and rushing down the stream. It sets within an hour and can be readily hidden by sprinkling pea gravel or sand over the foam while it is still slightly damp. It has some flexibility which accomodates the shifting of the rocks and ground structure over the winter.

Comes in a DIY can, or in the "Professional" size can which requires the use of a Foam Gun applicator.
