Black Waterfall Foam - 12 oz.

Black Waterfall Foam is ideal for use in pond and waterfall construction. It naturally blends with the landscaping of the pond. It is used to fill in cracks and holes between the rocks in a waterfall. When you fill in the cracks and holes it allows the water to flow over the rocks rather than between or behind them. This creates a more even flow of water. It also works very well for locking stones together.
