Most stabilisation specs are a guess.
A blend copied from the last job, dropped onto a site with completely different soil. It might work. It might fail at six months, but either way you find out the expensive way.
3SRM takes the guessing out. The blend is designed around your project, your constraints and your actual soil analysis. Nothing generic, nothing assumed.
What that means on the books:
— Less rework.
— Fewer variations.
— Less chance of a cost overrun blowing the budget.
— Faster sign off & practical completion
We’re on site within a week to start the analysis. The sooner we understand the soil, the sooner the site is stable and moving toward handover.

“Stabilised” is the most misused word on a civil site.
It doesn’t mean you’ve spread something on the ground. It means the surface is protected from erosion right now, to the GD05 standard.
Loose hay on a slope isn’t stabilised. It’s covered. Wind or rain shifts it, and the soil underneath is exposed again.
The test an inspector applies: if it rained hard tonight, would sediment leave this site? If the honest answer is yes, you’re not stabilised, whatever the invoice says.
This is why bonding beats coverage. Stabi-Mulch binds to the soil and holds, so it’s classified as stabilised under GD05 on application.

We used to import what we sprayed.
The quality wasn't there. It didn't bind. It didn't hold. Every imported batch was a gamble.
So we built our own.
Stabi-Mulch is NZ-made, mechanically shredded wooden fibre with 28% natural lignin glue. It holds 13x its weight in water. It's GD05 compliant the second it lands.
No one else in New Zealand has it and no one else can buy it.
It's not a product upgrade. It's in a category of its own.
