Atlantic Water Gardens LF1100 FallsFoam is a professional-grade black expanding foam formulated to seal voids and direct water flow over waterfall rocks instead of beneath them. Its high-density, closed-cell formula resists waterlogging and tolerates light foot traffic, helping maintain visible, natural-looking falls. Model LF1100 — 12 oz can for DIY waterfall and pond installations. Black, low-visibility foam designed to blend with rock and liner. High-density closed-cell composition resists waterlogging and UV degradation. Durable enough to withstand light foot traffic and outdoor exposure. Includes applicator straw for controlled dispensing and precise placement. Foam Cleaner (sold separately) dissolves uncured foam for easy cleanup. Shelf life: 1 year from born-on date; store in a cool, dry place. Use FallsFoam to fill gaps, voids, and seams so water flows over the rock surface rather than underneath. Apply in small amounts, allow the foam to fully cure before trimming, and avoid over-application; cured foam is durable and long-lasting. Product label and SDS are available for download; follow all safety instructions and wear appropriate PPE when applying.
