1. Thickened Canvas Base with Silicone Coating, Superior Waterproof Performance

   The sandbag uses heavy thick canvas as base fabric, added with upgraded silicone coating on inner surface. The compact silicone layer blocks water penetration thoroughly, avoids sand leakage and rainwater seepage, and prevents the bag body from being softened and damaged by long-time water soaking.

2. Classic Drawstring Quick Sealing Design

   Equipped with integrated drawstring opening, users can fill sand rapidly and tighten the rope in one second for tight closure. It prevents sand outflow during stacking and moving, saves construction time for emergency flood control, easy to operate without extra binding tools.

3. Durable Wire Screen Printing, Long-Term Fade Resistant

   Adopts professional wire screen printing technology. The printed flood control text and logos are firmly attached to the fabric surface, resisting sunlight, rain and friction. No fading or peeling even after long-term outdoor storage and repeated use.

4. 30*70cm Standard Reasonable Size

   30cm width *70cm length standard specification holds proper sand capacity. After filling, the sandbag forms stable rectangular barrier blocks, easy to stack layer by layer without sliding, ideal for building continuous flood walls at doorways, entrances and slope edges.

5. High Tear & Weather Resistance for Outdoor Use

   Thick canvas fabric owns strong tensile and tear strength, not easy to crack under heavy sand load. Silicone coating enhances anti-aging ability, adapting to sun, wind and rain outdoor storage all year round for flood emergency standby.

6. Multi-Scene Universal Flood Emergency Tool

   Suitable for municipal flood control engineering batch deployment, community property daily reserve, basement and garage water blocking, factory low-lying area flood prevention, convenient for centralized storage and rapid emergency transportation during rainstorm seasons.

This special flood control sandbag is professionally optimized for long-term outdoor flood prevention standby and sudden rainstorm emergency disposal. The base material selects thickened wear-resistant canvas fabric, which improves the overall tensile strength compared with thin ordinary sandbags and avoids breakage caused by sharp sand particles inside.

The inner layer is coated with upgraded silicone waterproof layer, forming an integrated anti-seepage barrier. It can effectively isolate rainwater and floodwater, stop water infiltration through fabric gaps, and keep internal sand dry without mud leakage to maintain stable weight for flood blocking.

The opening adopts classic drawstring sealing structure integrated with the bag body. After filling sand, just pull the drawstring tightly to lock the bag mouth firmly, which simplifies on-site flood control operation and improves the speed of stacking flood barriers in emergency situations.

All surface identification adopts wire screen printing craft. The printing ink penetrates into the fabric texture instead of simply covering the surface, so it will not fall off or fade after long-term sunlight exposure, damp environment and repeated friction, keeping clear identification for daily safety inspection.

With standard 30*70cm size, single sandbag has moderate loading capacity, easy for one person to carry and stack. It is a necessary standard flood prevention reserve product for cities, communities, factories and various low-lying building facilities.
