Material and Craftsmanship

Made with professional 7S*3 high-density strengthened canvas/thickened canvas/silicone canvas materials, offering excellent waterproof and wear-resistant properties. Special waterproofing treatment prevents leakage; reinforced edge stitching increases service life; dense internal stitching ensures filling doesn't leak out. Special non-slip bottom design improves stacking stability. Reinforced bag opening allows for quick sealing and opening. Silk-screen printing technology ensures markings remain clear and durable, resisting fading even under water-soaked conditions.

Color/Style Display

Internationally recognized flood emergency warning color, highly visible and easy to identify. Clear recognition even in night or low-light environments. The eye-catching appearance clearly indicates "Flood Prevention Sandbag" purpose, aiding quick identification and classification in complex environments. Custom printing of unit names, numbers, and other markings available upon request, while maintaining the warning color for safety recognition.

Application Scenarios

River Breach Blocking: In emergencies, 25×70cm sandbags can be quickly stacked in "horizontal-vertical" structure, building temporary 30-meter flood walls hourly, effectively blocking flood spread.

Urban Waterlogging Prevention: 30×70cm sandbags create drainage channels in low-lying urban areas, guiding water toward drainage systems. Each sandbag group can control water direction across 50 square meters.

Underground Passage Sealing: 40×60cm large sandbags rapidly construct water barriers at underground passage entrances, withstanding 1.5-meter water pressure, protecting important underground facilities from flooding.

Embankment Reinforcement: Multiple sandbag sizes used alternately form stable triangular stacking structures, completing 100-meter embankment height increases of 30cm within 2 hours for emergency projects.

Usage Method

Open the sandbag, fill with sand to about 80% capacity leaving space for sealing, seal using drawstring/zipper closure, and stack as needed. Use "one layer horizontal, one layer vertical" alternating pattern to improve wall stability. Arrange bottom layer in triangular layout to enhance foundation stability. For large-scale use, lay a base layer of sandbags first, then gradually narrow upward to construct flood walls, reducing sliding risk from water pressure.

Maintenance Guide

Store in dry, ventilated places, avoiding prolonged humid environments to extend service life. Inspect sandbag integrity before use to ensure no damage; if not seriously damaged after use, clean and dry thoroughly for reuse. Regularly check inventory sandbags and test sealing performance. Under normal conditions, products can reach 3-5 years of service life, ensuring usage needs for one complete flood season in emergency conditions.
