Large-scale civil infrastructure projects demand reliable plant establishment, low loss rates and landscapes that perform under pressure.
At the Piarere SH1/SH29 roundabout upgrade, MyNoke supplied over 6,000 tonnes of MyNoke Black Gold vermicast to support planting and turf establishment across the site.
Working in partnership with Evergreen Landcare and alongside Downer, JC Civil Construction, Midgley Developments and Terra Lana Products Ltd, vermicast was blended with existing site soils to improve growing conditions across the project footprint.
Eight months on, the establishment results have been exceptional.
Two Years' Growth in Eight Months
Bryce Alsemgeest, General Manager at Evergreen Landcare, shared:
“Evergreen Landcare have used the MyNoke Black Gold vermicast on our planting site at the Piarere SH1/SH29 roundabout mixed with site soils. The plant growth we’ve seen in eight months is usually what we would see after two years, which is outstanding!”
For civil contractors, councils and project managers, accelerated plant establishment translates into:
- Faster canopy development
- Earlier visual impact for high-profile public infrastructure
- Stronger root systems before seasonal stress
- Reduced plant replacement costs
Bryce continued:
“The growth on the planting was strong and vigorous for the relatively short time they have been in the ground and over the whole site we have had very few plant losses.”
Low mortality across a large-scale site improves programme certainty and reduces maintenance inputs during establishment and defects liability periods.
Improving Soil Performance at Scale
Civil landscape environments often involve compacted subsoils, low organic matter and biologically inactive growing media.
By incorporating over 6,000 tonnes of vermicast into site soils, Evergreen Landcare significantly lifted organic matter levels and biological activity across the planting and turf areas.
Bryce noted:
“MyNoke Black Gold was easy to work with and blended well with the existing site materials. The high levels of organic matter in the vermicast has provided a great media for the planting and turf areas.”
Ease of use was critical. Vermicast integrated seamlessly into bulk soil blending operations, supporting efficient on-site workflows without disrupting construction timelines.
Why Vermicast Makes Sense for Civil Infrastructure Projects
MyNoke vermicast supports:
- Increased soil organic matter
- Enhanced microbial activity
- Improved soil structure and aeration
- Greater moisture-holding capacity
- Stronger, more resilient root development
- Reduced plant losses
On infrastructure projects where landscape performance is publicly visible and contractually accountable, these outcomes matter.
Supplying more than 6,000 tonnes to a single project also demonstrates MyNoke’s ability to operate at true civil scale. Across our operations, MyNoke processes approximately 140,000 tonnes of organic waste per annum into high-quality vermicast, enabling bulk supply for major North Island infrastructure works.
Planning a Civil Tender or Landscape Specification?
If you are:
- Preparing a civil infrastructure tender
- Writing landscape specifications
- Managing council planting programmes
- Delivering subdivision, roading or infrastructure upgrades
Vermicast can be incorporated early in design and specification to improve establishment performance and reduce risk.
