Hi-Vis Barriers are 10-foot, water-activated containment barriers designed for quick, flexible flood and spill control. When wet, they expand to 3.5 inches tall in about 10 minutes, creating a bright, safe barrier without the need for sand or manual filling. Length and expansion: 10 ft long; expands to 3.5 inches in height within 10 minutes when activated by water. Absorption capacity: each barrier absorbs up to 8 gallons of water using a super absorbent powder that swells and gels as it takes in moisture. Activation method: water-activated—simply get them wet; no sand, pumps, or heavy labor required. Color and safety: durable hi-vis orange enhances visibility on worksites, improving safety around containment zones. Installation versatility: designed to lay flat, stack, or stand vertically to fit straight runs, curves, or irregular contours. Materials and environmental impact: safe, non-toxic, and eco-friendly, with barriers that decompose over time after disposal. Limitations: not suitable for salt water; exposure to salt water triggers a chemical reaction that causes deflation. Documentation: Safety Data Sheet and warranty are provided with the product. These barriers are ideal for rapid containment in settings like construction sites, temporary flood defenses for properties, and spill or stormwater management around facilities. They reduce labor and logistics compared with traditional sandbags, offering quick deployment by a single team. The ability to lay them flat, stack for height adjustments, or stand them upright makes them adaptable to channels, doorways, trenches, and irregular flood paths. Their bright orange color and straightforward activation support safer, more efficient responses to water ingress and contaminated runoff, while their on-site versatility helps keep work areas and drain points protected during cleanup and dewatering efforts.
