  • Hydro-seeding and hydro-mulching


Hydro-seeding is advanced method of quickly applying water, seed and fertiliser to a large area. It is especially useful in uneven and difficult to access areas.

In many cases results are improved through the addition of a tackifier. This helps hold seeds in place during the germination phase. Water$ave Hydro-Tac is a stand-alone tackifier that can be used without the addition of mulch.

As well as reducing seed loss during wind or rain event, Hydro-Tac also reduces evaporation, improves water infiltration and improves the physical properties of soils. Its anionic properties allow small colloidal particles to bind together, reducing loss of top-soil and hard-panning.

Hydro-Tac is an anionic, linear polymer in powdered form. It is soluble in water and can be used with a marking dye.

It is non-toxic and biodegrades over time, with no bio-accumulation in the soil.

Hydro-mulching Solutions

Hydro-mulching is the application of water, seed and fertiliser in combination with a growth medium (eg paper pulp, sugar cane or straw mulch).

It is common to introduce a binding agent into the slurry before application to help stabilise the mulch and retain moisture.

Water$ave Hydro is a blend of superabsorbent and linear polymers designed specifically for Hydro-mulching. The absorbent polymer particles absorb both water and fertiliser, and release them over time, leading to better strike rates and fewer dry or bare spots. The addition of a linear polymer to the blend acts as a binder that helps the mulch bind together and stay in place while the seeds germinate.

It is important to add can revegetate and cover a vast area very quickly and represents a scientifically advanced way to revegetate compared to other conventional methods including direct seeding and drill seeding. It can be used to revegetate areas that are difficult and/or dangerous to access, as well as moderate slopes with the addition of a binder, making the task of providing erosion control for verges or soil stockpiles much easier. Binders form a hard crust and work to bind soil to the seed, preventing erosion, increasing water retention and promoting faster germination of seeds.
