What is Foamstream?

Its patented low-pressure process combines hot water and biodegradable foam, made from natural plant oils and sugars, making it safe for use around people, animals and delicate environments. With the lance sets, it can also be used for chewing gum removal, pressure washing and general sanitation jobs too, making it a highly effective, all-round, green space and urban management system.

Committed to ensuring that they deliver the safest, most environmentally friendly products, Weeding Tech can guarantee to their customers that their foams have been cleared for use as an organic, non-toxic, safe product by the four bodies listed above and also:

• Australian Pesticides and Veterinary

• Medicines Authority


• Health Canada


• Biogrow NZ

How does it work?

The active ingredient in the process is the heat in the hot water. The foam simply acts as an insulating blanket over the top of the hot water, ensuring heat is not lost to the atmosphere. Using their industry-leading machinery, Foamstream is applied to vegetation at low pressure and can be used in all weathers. Once it hits the vegetation and covers it, the foam creates a thermal blanket over the vegetation and the water.

Why is it so effective?

Just like the roof on your house, the foam stops the heat from the hot water escaping to the atmosphere, trapping it and holding it directly on the plant for an extended period of time. The heat penetrates the leaf’s waxy outer layer, travels down the stem, and into the roots – killing or severely damaging the plant, causing it to die. The longer a plant is kept in the kill zone (temperatures above 57˚C) the more effective the heat will be at killing the plant. By providing a layer of insulation on top of the water, Foamstream allows the heat in the hot water to be held within the kill zone for longer than any other alternative thermal method.

What does this mean?

Foamstream provides the most effective way of killing vegetation, meaning fewer treatment cycles are needed per year compared to any other alternative thermal method of weed control. By needing fewer treatment cycles, less labour is needed over the course of the year, reducing overhead costs for customers.

In addition to killing the plant, Foamstream also sterilises surrounding seeds and spores that haven’t yet germinated, helping reduce future weed growth.

By combining the most effective method, the fewest treatment cycles per year and the ability to sterilise seeds and spore, Foamstream offers customers the lowest cost of ownership and operation cost in the alternative herbicide-free space. As Foamstream can also be used for so much more than just weed control, the commercial case for using Foamstream over alternatives comes highly attractive.
