Product Details

Constructed from high-density, commercial-grade 18oz to 20oz PVC vinyl tarpaulin, these ballast bags are engineered to endure rigorous rental use. The material features exceptional tear resistance, UV protection, and fireproof properties. Utilizing high-frequency hot-welding technology, the seams are permanently fused to create a 100% leak-proof, burst-resistant, and airtight seal. This robust design guarantees that the bags maintain structural integrity and prevent water seepage under maximum weight loads.

Secure Valving: Each water weight is equipped with a tight, double-capped screw inlet or an industrial air/water valve that allows for rapid filling and draining while preventing accidental leaks during operation. Reinforced Handling: Heavy-duty, ergonomic carrying handles are securely welded onto the top surface. This placement permits effortless transport, lifting, and placement on-site even when fully filled with liquid. Versatile Anchor Points: Strong built-in rings or D-rings allow operators to clip multiple bags together or tie them directly to the inflatable's structural anchoring points using standard carabiners or heavy strapping.

By capitalizing on on-site water sources, these bags eliminate the exhausting logistical burden of transporting hundreds of pounds of sand or solid metal weights back and forth from a warehouse. Operators can arrive light, quickly fill the bladders to achieve substantial ballast support, and safely secure the attractions. Once the event concludes, simply open the valves, dump out the water, and collapse the flexible PVC shell flat. This space-saving design ensures clean storage and significantly reduces transport fuel costs.
