Quick and easy to use in 3 steps

1. Activate the bag
Water the bag with tap water (watering can, garden hose) or by immersing it in water for 3 to 7 minutes to weigh it down. The bag reaches its optimal shape when it measures between 12 and 15 cm in height.

2. Place the tarps
The bags come with opaque tarps. For optimal durability, use these tarps to protect the bags from the elements and prolonged UV exposure. When using multiple bags, the tarp ensures a better seal for the barrier. Place the tarp in front of the area to be protected.

3. Position the bags
Place the bags on the tarps. Then, fold them back to completely cover the barrier.
