Soil erosion and poor vegetation conditions can cause havoc on worksites, developments, mines, quarries, unsealed roads and other areas of large-scale land. Hydromulching has evolved to be one of the most efficient, cost-effective solutions for sustainable land rehabilitation in Australia, with the latest methods offering long-term results that can save councils, government bodies and other land managers countless money.
If you have an issue with poor soil or vegetation conditions or environments, including those in difficult-to-access areas, like steep slopes, you’ll want to read this. Our guide to hydromulching as a cost-effective sustainable land rehabilitation solution will give you all the information you need to take the next step.
Ways Soil Erosion & Vegetation Instability is Costing You Money
Dispersive soil, AKA soils with high clay content and other aggregates, break down easily when exposed to water, and unfortunately is very common in Australia. This breakdown can lead to many long-term issues, including:
-
- Fines and non-compliance penalties if strict erosion and sediment control requirements are not being met.
- Increased costs to rework and rehabilitate the site, including cost of labour, materials and equipment costs.
- Damage to stormwater systems drains, nearby roads, wetlands and waterways, and asset zones, including asset tracks.
- Project delays and operational downtime caused by problems.
So, getting dispersive soils under control with a cost-effective solution, like hydromulching, is highly beneficial to you and your community. Plus, there are a number of other benefits of hydromulching you can appreciate too, including reduced maintenance.
How Hydromulching Works At Repairing Dispersive Soils
How hydromulching works is by combining mulch, seed, fertiliser, glue and water that is sprayed evenly across an area of prepared land.
This helps to create a protective barrier over the soil for short-term erosion control, while providing a long-term soil stabilisation solution by creating even, thriving vegetation. It holds moisture in the soil, supports seed germination and protects against heavy rain or wind disturbance. Unlike traditional seeding, hydromulching provides consistent coverage, even on slopes and uneven ground.
As a result, it helps fix dispersive soils by:
-
- Improving soil structure, locking it in place and preventing erosion before roots can establish.
- Rebuilding stable soil aggregates by incorporating gypsum, biochar and other organic matter into the slurry.
- Enhancing water infiltration, using special additives to reduce water runoff and increase soil moisture retention.
- Increasing germination and growth speed, using custom seed blends and biotic soil amendments for rapid vegetative establishment and growth.
Why Hydromulching is a Cost-Effective Solution to Sustainable Land Rehabilitation in Australia
Reduced soil erosion and maintenance needs.
When hydromulching is applied, it immediately covers the bare ground with a bonded mulching layer, drastically reducing erosion from wind and rain. This helps to prevent costly issues, such as:
-
- Topsoil loss, increasing your costs to regrade and replace soil.
- Sediment runoff, potentially damaging nearby assets or leading to fines.
- Ongoing reworks, such as re-seeding or erosion mat replacement.
As the vegetation establishes, it also helps stabilise the soil, reducing your need for repeat treatments or temporary erosion control methods.
Improved water retention and reduced irrigation requirements.
Think of the mulch in hydromulching like a sponge, retaining water directly at the soil’s surface where the seeds need it most. Long-term, this helps:
-
- Reduce the need for watering, saving on irrigation infrastructure, water usage and labour.
- Increase success rate of vegetation establishment, particularly in drier climates.
That water being locked in the soil helps support germination during its most critical stages of development, even in low-rainfall seasons or remote areas.
Enhanced soil health and long-term vegetation stability.
Hydromulching isn’t a temporary fix. It’s a long-term solution for enhancing the soil’s ability to support vegetation long into the future. As the mulch in the hydromulch mix decomposes, it:
- Adds organic matter to the soil, improving the soil’s fertility and structure.
- Encourages microbial activity and better nutrient cycling.
- Supports deep root systems, making vegetation more self-staining and resilient.
