【Quick Expansion Steps】
1. Lay the entire L15LH sandbag flat and fully extended on a surface.

3. Gently press the sandbag to distribute the SAP evenly and avoid uneven expansion.
4. Once expanded, stack as shown below for flood protection.


【Frequently Asked Questions】  
Q1. The surface becomes wet after soaking the tech sandbag — any usage advice?
　　Due to the high absorbency of the tech sandbag, water may seep downward after it is removed from water, causing the ground to become wet. This is normal and does not affect performance. To prevent prolonged dampness, place an absorbent pad or waterproof sheet underneath to help with drainage.

Q2. Why does the WB-L15LH long strip tech sandbag expand only on one side?
　　This may happen if the sandbag wasn’t fully laid out or if the SAP inside wasn’t evenly spread before use. When watered in this state, the side without SAP may not expand, while the other side may over-expand and rupture. To ensure proper use, always spread the SAP evenly before use and refer to the “Quick Expansion Steps” above. 

Q3. The ground is slippery after use—how to fix it?
　　If the ground becomes slippery after using the tech sandbag, we recommend spraying saltwater and wiping the surface to reduce slipperiness and ensure safety when walking. The SAP inside is non-toxic and odorless, and safe to touch. If it comes into contact with skin during cleaning, simply rinse off with clean water.

Q4. Can the tech sandbag return to its original state after expansion?
　　Once expanded, the tech sandbag cannot return to its original dry state. No tech sandbag on the market can fully revert to its unused condition after absorbing water. If you wish to reuse it, refer to the “Reusable Usage” in the detail diagram on the left for storage tips until the next rainy season.

Q5. What is the effective lifespan of the sandbag?
　　The lifespan of the sandbag depends on factors like usage frequency and environmental conditions. Under normal circumstances, with proper use and maintenance, it can retain good performance for two to three seasons. Regularly inspect the sandbag for cracks or damage, and replace it promptly to ensure reliable flood protection when needed.


【Precautions For Use】
▲Not edible.
▲For use in freshwater only: Water temperature ≥ 18°C; pH between 5 And 8.
▲Do not soak for more than 2 minutes to avoid over-expansion, which may cause water to leak when stacked under pressure. 
▲After removing the sandbag, lay it completely flat and evenly distribute the internal SAP material to avoid uneven expansion.
