1. What are the parking safety supply essentials for my facility?
A: Each model serves a unique purpose. Heavier barriers, like Yodock and Safeguard, work best for traffic control and jobsite protection, while lighter designs are used for parking, pedestrian areas, and events.
2. What materials are Water Barriers made of?
A: Depending on the model, they’re made from rotomolded plastic, blow-molded plastic, or UV-resistant polyethylene, all built for durability in outdoor environments.
A: No. They’re shipped empty to make freight more affordable and are filled on-site with water or sand.
A: Fill capacity varies by model, typically ranging from 50 to 130 gallons once filled.
A: Connection systems vary — some use steel pins or bolts, others have built-in couplers for quick linking. All provide a secure connection for continuous lines and safe site layouts.
A: Regular inspection and cleaning can extend the life of your equipment. For example, repaint worn striping, check bollards for damage, and replace reflectors if visibility decreases.
A: Most models range between 6 to 10 feet long and 32 to 42 inches high, giving flexibility for different applications and space constraints.
8. Are Water Barriers certified for safety?
A: Models like Yodock 2001MB and Safeguard 36 are MASH-tested and approved, meeting safety standards for work zones and controlled traffic areas.
A: Yes. Some models can be ordered in different colors or with logo printing for branding, visibility, or directional guidance.
A: It depends on your setup. MASH-tested models are best for traffic management and long-term sites, while lighter, portable barriers work well for events, parking, and pedestrian control.
