Water Sandwich is the paper and jute with an inner layer of granular polymers in dry form. The polymer absorbs 100 times its own weight of water, retaining water at binding tension.

Placed at root level, the pads increase farmers’ irrigation efficiency by 40%, while increasing yields between 10 and 25%. With this technology, young plants and trees are significantly more likely to survive the dry times. Costing about mere pennies per plant with lifetime of 5 years, Water Sandwich are low-cost, easy to produce and reliable for farmers in arid regions.
