Wētā Dam Bags - 6 Pack

The Wētā Dam sack is an eco-friendly and 100% biodegradable replacement of the traditional sandbag to control the flow of water.

Comes in a pack of six.

Our bags are made of jute which means they soak the water quicker than some nylon alternatives. They're nice and heavy too - swelling to roughly 20kgs. When activated the sack’s height is approximately 15-18cm.

Directions:

• Pre-soak the Wētā Dam sacks for approximately 5 minutes to activate. Sack will swell to a weight of approximately 20kgs.
• Alternatively, you can place the sacks, partially absorbed or dry, into position. Place a weight on top to secure the sack.
• The dry, or partially dry, sacks will swell upon contact with rain or the breaching water.
• When positioning the Wētā Water Barriers ensure the ends are firmly against the adjoining barrier to avoid leakages.
•  When stacking for height to accommodate the volume of water, ensure the sacks are staggered when placed on top of one another to strengthen your barrier wall.

• Suitable for housing, river banks, streets, basement, underground parking lots, warehouses etc.

Storage after use:

• The Wētā Dams can keep their effectiveness for at least 2 months while remaining wet. 
• To dry out the sacks, keep outside in the shade. For optimal drying allow for 2-3 months. Keep out of direct sunlight. 
• Shelf life- at least 4 years
• The used Wētā Water Barrier can be reused, however, the speed and efficiency is not as productive as the initial use.
