Hydroganics is an exciting ‘hydrocompost’ solution. It offers a major land revegetation and erosion control alternative for property developers, commercial landscapers, infrastructure contractors, government agencies, and mine owners and contractors. Clients benefit from an affordable, high-quality, compost-based germination media and erosion control solution unlike anything else in the market.
Hydroganics uniquely combines:
- Germination media using NuGrow’s industry leading compost, with up to 20 times the organic material of traditional hydromulch
- Wet application, supporting instant activation of binding agents/tackifiers
- Seed optimisation, embedding seeds directly in the germination media for faster growth
- Instant erosion control and soil protection, supported by a fibre-based matrix.
Hydroganics is available at budget, traditional and premium levels based on client objectives and site requirements, determined in consultation with a Hydroganics representative. This gives maximum flexibility in pricing and delivers a service that is neither ‘over-specified’ nor compromised.
All sites are assessed to inform a tailored solution including seed mixes. Clients then have the option of soil testing and incorporating wetting agents and ameliorants in the single pass application. The Hydroganics team can collaborate with soil scientists, ecologists and seed experts to guide this tailoring process.
Application rates are impressively fast, with the added advantage of easy access around difficult terrain. Once applied, the benefits of the specialised compost come to the fore, featuring slow-release nutrients – particularly nitrogen and phosphorous – and an injection of organic carbon back into the soil. This re-builds soil structure, organic matter and fertility, creating long-term value. Furthermore, when the Hydroganics process is followed, ongoing maintenance for clients is generally minimised.
- Ensuring cost-effective application of the germination media at 3mm to 15mm deep
- Reducing sacrificial seed through an optimised seed density and depth
- Enabling application rates of up to 10,000m² per day
Olsen Avenue road upgrade, Gold Coast
This project targeted long-term batter stabilisation spanning a 2,500m² site with extremely poor soil. Hydroganics delivered a superior, topsoil-free solution to the originally specified use of imported topsoil and double-pass hydromulch. Cover crop and native seeds were injected as the organics were applied at a rate of 100m³/ha. The site quickly stabilised, native species germinated within three weeks. Within 20 months, natives were flourishing with extensive germination up to 3m tall.
Toowoomba Second Range Crossing, Toowoomba
HL Landscapes for Nexus
Hydroganics was used for almost 50ha of some of Australia’s most extreme construction landscape, including 100m-tall batters, at 45° angles, with multiple benches. Traditional revegetation methods weren’t possible for environmental, safety or cost reasons. Despite high temperatures and multiple extreme weather events, immediate erosion control was achieved and growth since has been successful, including where works integrated with rock-fall wire netting and erosion control matting.
Warrill View Road, Rosewood
Our client had originally specified a topsoil/turf and topsoil/bonded fibre matrix hydromulch combination for this 11,000m² site. Hydroganics offered a topsoil-free solution for stabilising and vegetating roadside drains as part of a shoulder widening project. Rapid establishment was needed due to the high risk of storm damage, with our team increasing the tackifier used and heavily watering the area to promote fast germination. Results were outstanding and achieve all client objectives.
Bruce Highway interchange, Tinana
We were brought in to stabilise and vegetate 28,000m² of roadside batters around the interchange upgrade, using Hydroganics at 100m³/ha to deliver a topsoil-free solution. The project featured a combination of fill and cut batters with highly varied properties. Our team used two amelioration regimes to deliver tailored treatment results – both of which quickly stabilised and saw positive growth soon after. Our team’s efficiency saw us safely working in and around live traffic for a fast solution.
