In Australia, the cost of hydromulching varies depending on a few factors. These include:
- Size of your property or planting area
- Seed type you choose based on your soil type and growing conditions
- Seed density
- How prepared your soil is for slurry application — for example, if the ground requires additional topsoil or grading, this will increase your hydromulching costs
It is important to note that larger projects can cost less than smaller projects, causing little difference between residential and commercial projects. Why is that? Well, in terms of fixed costs, hydromulching services still take the same amount of time, expertise and equipment to perform a project of any size. If you have a larger area to cover, it distributes the hydromulching costs so it may work out to be cheaper.
The average cost to hire hydromulching services can vary between $0.06 and $0.20 per square foot of land. The cost sits between $2,000 and $4,000 per acre. However, if you have less than an acre of land, your contractor might charge you by the hour instead. In this case, their professional rate applies and you may pay between $24 and $30 per hour.
