Super Absorbent Polymer (SAP) / Hydroseeding Water Retainer
Product Features
Powerful water absorption & retention: Absorb hundreds times of its weight water, lock moisture and release slowly during dry period.
Good compatibility for hydroseeding: Granular form mixes evenly in hydroseeding slurry, compatible with hydroseeding binder and wood fiber.
Improve soil structure: Optimize porosity of substrate, prevent crusting, help plant root growth.
Repeated water absorption & release, long service life, cut irrigation frequency.
Seed-safe mild property, no negative impact on seed germination.
Recommended Dosage
5–10 kg per ton of hydroseeding materials
Or 5–15 g/㎡, higher dosage for rocky & arid slopes
Tip: Add into hydroseeder tank together with other materials; initial watering after spraying helps full swelling.
Application
Hydroseeding revegetation for highway, railway & municipal slopes
Soilless greening for mines and quarries
Soil erosion control for river banks & reservoir drawdown zones
Ecological restoration on dry hills and construction spoil yards
Landscape planting & seedling transplanting
Notes
Store sealed and dry; moisture will weaken absorption capacity.
Keep away from strong acid & alkaline additives.
Initial watering after hydroseeding promotes full swelling.
Adjust dosage according to local rainfall and slope condition.
Water retainer is high-performance super absorbent polymer specially for slope hydroseeding and barren land revegetation. Used together with hydroseeding wood fiber, binder, grass & shrub seeds and growing medium. It absorbs and stores water to supply seedlings steadily, reduce water loss from slope surface, improve seed germination rate. Widely used in highway & railway slope, mine restoration, riverbank and spoil yard ecological works.
