Quick Dam Indoor Water Dams provide fast, reliable water containment for home and property protection. These absorbent barriers lay flat until activated, then swell to form a 2.5" high berm in about 5 minutes to stop leaks and spills at the source. Activation and swelling: Lays flat until you activate it with water; swells to 2.5 inches high within approximately 5 minutes to create a protective berm. Absorbent containment: Inner absorbent is completely contained to prevent seepage and keep the surrounding area dry. Visibility and durability: Durable Hi-Vis Orange knit for easy placement and ongoing visibility as it expands. Material and construction: Built for indoor water control applications with a focus on reliability and practical use around equipment and access points. Size, portability, and storage: Compact and lightweight, easy to store between uses and quick to deploy when needed. Not for salt water: Chemical reaction to salt water causes deflation, so use with fresh water only. Ideal for indoor use cases: Condensation buildup, water-based spills, wrapping around leaky pipes or hot water tanks, and preventing water from entering doorways, windows, or other vulnerable areas. In practical terms, these water dams help you contain and control indoor water problems with minimal setup. Use them to quickly cap condensation on exposed lines, divert spills during cleaning, or wrap around leaking equipment to buy time before repairs. The quick deployment, contained absorbent core, and compact storage make them a practical choice for homeowners, renters, and maintenance staff facing episodic leaks or moisture control challenges.
