Hydroseeding & hydro mulching have become essential practices for fast & effective revegetation across a range of Australian landscapes. From mine site rehabilitation & roadside erosion control to parklands & new developments, these spray-on techniques offer speed, coverage & cost-efficiency. But even the best seed & mulch mix can fall short if it lacks the ability to retain moisture & hold firmly to the ground; especially in dry, sloped or exposed areas. To address these challenges, Polymer Innovations has developed two advanced polymer solutions: Water$ave Hydro & Water$ave Hydro-Tac. Designed to enhance every stage of the hydroseeding process, these products offer the next step forward in moisture retention, soil stability & mulch adhesion.
The Role of Polymers in Hydroseeding
Traditional hydroseeding mixtures contain seeds, mulch, fertiliser & a tackifier to bind it all together. Previously, organic tackifiers like guar gum or starch have been used to stick the mix to the soil. These natural options break down quickly, especially in high winds, heavy rain, or intense sunlight, leading to reduced seed-to-soil contact & lost productivity. Polyacrylamide-based polymers offer a more robust solution. These synthetic, water-soluble compounds work at the microscopic level to hold soil particles in place, reduce erosion & improve water availability in the root zone. The result is faster germination, better establishment, & less rework over time.
Water$ave Hydro: Moisture Retention with Soil-Stabilising Power
Water$ave Hydro is a specially formulated lineal anionic polyacrylamide. When included in a hydroseeding mix, it enhances water infiltration & retention in the soil, creating an environment where seeds can germinate & establish more reliably. It also flocculates fine particles, forming a light, stabilising film on the soil surface that reduces crusting & runoff.
Water$ave Hydro helps keep the seedbed moist & stable. It's particularly valuable in dry climates or on sites where watering is irregular. It integrates smoothly into hydroseeding applications without disrupting the mix & is safe for all vegetation types; from native grass species to high-performance turf.
Water$ave Hydro-Tac: The Polymer Tackifier That Outperforms
For those working on exposed sites or steep embankments, Water$ave Hydro-Tac is a superior alternative to traditional tackifiers. It forms a fast-drying, durable bond that holds the seed, mulch & soil together; even under wind, rain, or foot traffic.
Unlike guar-based tackifiers that may degrade or fail under stress, Hydro-Tac creates a longer-lasting bond with excellent adhesion properties. It’s ideal for use in large infrastructure projects, mine sites & any application where mulch needs to stay firmly in place until vegetation takes hold. The product is non-toxic, environmentally safe & designed for compatibility with all common hydroseeding components.
Designed for Australian Conditions
Both Water$ave Hydro & Hydro-Tac are developed to meet the harsh conditions of local climates & soil types. From drought-prone regions to areas affected by erosion & heavy use, these polymers are built to deliver results where traditional materials fall short. Contractors, councils & environmental specialists who integrate Water$ave products into their hydroseeding work report improved germination, stronger ground cover & less maintenance across a wide range of projects.
Smarter Hydroseeding Starts Here
In revegetation, success depends on how well your mix stays in place & supports seed growth. With Water$ave Hydro & Hydro-Tac, you're not just applying seed & mulch; you're building a more stable, water-efficient foundation for healthy plant growth.
