The Taiga Black Expanding Foam Sealant is a specialist solution for building and maintaining ponds, waterfalls, and water features. Engineered for strength and versatility, it bonds to a wide range of materials—porous and non-porous—including rock, stone, wood, cement, and cloth, making it ideal for sculpting water flow and sealing structural gaps.

Its dense expanding formula excels not only in bonding but also in filling large cracks and cavities, guiding water over rocks rather than letting it seep beneath. Once cured, the foam is water and mildew-resistant, and also offers thermal and acoustic insulation. The black finish ensures a natural, discreet appearance that blends into most pond and landscape designs.

Each can delivers up to 45 litres of foam depending on environmental conditions, providing an efficient and cost-effective solution. A fire-retardant additive adds to the safety profile, while the simple straw applicator system allows for easy, precise use. After application, the foam cures within 24 hours into a durable, solid bond.
