Stabi-Mulch

Stabi-Mulch is New Zealand’s only locally made hydro mulch — a powerful, all-in-one spray-on solution that instantly controls erosion, locks in moisture, and accelerates lush vegetation growth faster than traditional methods.

Trusted by Developers. Approved by Councils. Proven by Results.

How It Works

Stabi-Mulch is applied as a slurry using hydroseeding equipment, delivering a fast, efficient erosion control and revegetation system in one step:

  1. Slurry Application
    A mix of water, NZ-made wooden fibre mulch, grass seed, fertiliser, and a binding agent is sprayed directly onto bare or disturbed soil.
     

  2. Instant Bonding
    Upon contact, the slurry forms a permeable crust that adheres to the soil — locking it in place and protecting it from wind and rain.
     

  3. Erosion Control Begins Immediately
    The mulch layer shields the surface from dust, water runoff, and topsoil loss, stabilising the site from day one.
     

  4. Moisture Retention & Seed Germination
    With the ability to hold 13.78 times its weight in water, Stabi-Mulch keeps the soil damp, creating ideal conditions for seed growth.
     

  5. Fast, Healthy Vegetation
    The result: strong, even grass strike — up to 80% faster than conventional methods — with long-lasting erosion control benefits.

Immediate Erosion Control

Immediate erosion control within 4 hours of application, significantly reducing the risk of sediment run-off and erosion. Meaning cost savings and significantly reduced risk

Faster Grass
Strike

Holding 13 times its weight in water Stabi-Mulch provides an excellent growing environment for the seed, encouraging a fast grass strike and long-term stabilization via vegetation cover. Even just a 40% grass strike can reduce sediment run-off by up to 70& when compared to bare soil. 

No Weed Contamination

Stabi-Mulch is thermally refined, meaning the only seeds introduced to sites are the certified seed blends added to the slurry.

Dust
Control

As soon as Stabi-Mulch is applied there is no risk of dust issues from this site as the mulch creates a strong crust with the surface particles, stopping them from coming air born.

“With Stabi-Mulch™, you’re not just stabilizing soil—you’re stabilizing your timeline, your costs, and your final inspection. Projects that would drag on for weeks or be vulnerable to rain can now be locked in fast—saving you tens of thousands in labour, rework, and payment delays".
