FAQ

Does Foamstream work as well as herbicide?

Yes. Foamstream is the world’s leading herbicide free method for killing weeds and moss. When it comes to treatment cycles and overall efficacy, is the closest thing to herbicide. In the case of moss, we believe that it is more effective. It is the result of a long journey towards developing a state-of-the-art system which kills weeds using a precise combination of very hot water and our patented biodegradable foam (the Foamstream itself).

Is there anywhere where Foamstream can’t be used?

Foamstream can be used anywhere except in the middle of large bodies of water. It is particularly well suited to treating sensitive environments, waterways and SSSIs where the use of traditional chemical herbicides is restricted.

Why is hot foam more effective than hot water?

There are a number of key reasons:  

  • It works better than hot water alone, and costs our customers less  
  • There is no system in the world as effective on moss and algae as hot foam Π Foamstream requires less treatment cycles than any hot water product on the market
  • Unlike hot water, hot foam results in important savings of limited resources of water and diesel and does not require the use of strong decalcifying chemicals

Please refer to our fact-sheet for more info.

Is Foamstream only designed to be used for weeds?

No, it has also been proven to be effective on many different types of vegetation including moss which requires just one treatment cycle.  We also sell optional lances which can be used as an added extra for cleaning and chewing gum removal.  

Can the system be used in any other settings?

Yes absolutely. Our equipment comes with a lance which can be used to clean away chewing gum and tackle all manner of street cleaning requirements. Furthermore Foamstream allows our users to treat the greatest variety of surfaces, far more effectively than any other solution.

Do you have other products in the current range?

We are currently building on our amenities range and there are a number of new products which are in development, including a smaller version of our machinery for use in smaller town and village environments as well as a larger version which can be used in settings such as on motorways, highways or major long stretches of road.  We are also actively exploring new product development in the horticulture and viticulture sectors.

Can I rent or hire the MW-Series?

Yes you can in many of the regions we cover. You can find out whether rental options are available in your area by getting in touch with your local distributor. If you cannot find a local distributor, please contact Weedingtech HQ for more info.

What scientific studies have been done to confirm Foamstream’s safety?

The foam itself is made from 100% biodegradable, organic materials, making it completely safe and sustainable no matter where it’s used. The Chemicals Regulation Directorate (CRD) has confirmed that Foamstream is not considered to have a pesticidal effect in the context of EC Regulation 1107/09. We can also supply a safety data sheet according to EC Regulations 1907/2006 (REACH) and 1272/2008 (CLP) upon request. Foamstream has regional approval from all countries in which we operate and is approved for organic use. Furthermore, multiple scientific studies, from the Clean Region Project, to independent research by experts such as Dr Arndver Schwele at JKI and Dr. David Hanke at Cambridge University, have conclusively proven that water insulated by the addition of foam, delivers greatly improved weed and vegetation control compared to systems which use only hot water.

Does Foamstream work with invasive weeds?

Yes. We’ve seen particular success with Crassula and other invasive species that grow up around water.

How quickly does Foamstream take effect?

The effects of Foamstream are visible within minutes; the cell walls of treated weeds rupture as soon as the foam is applied and the weed discolours noticeably. Watch our Foamstream film to see the process in action.

What is Foamstream made of?

Foamstream is made from natural and sustainable plant oils and sugars derived from potatoes, maize, wheat and rapeseed oil.  All materials used in the manufacturing process are non-GM and from sustainable sources. Although we use less than 0.001% palm oil in Foamstream, it is certified as sustainable through the GreenPalm programme run by the Roundtable for Sustainable Palm Oil (RSPO). We are also launching a premium, palm-free version of Foamstream later this year. Read our environmental policy here.

How does Foamstream work?

Foamstream works by applying heat to the weed in the form of hot water and foam. The foam acts as a thermal blanket, keeping the heat on the weed long enough to kill it. The density of the foam is such that it doesn’t blow away in the wind or wash away with rain. Read more here.

Why is foam necessary?

Any thermal treatment is quite simply about the most effective transfer of heat to the plant.  Thermal burners, hot water systems and steam units all suffer from huge losses of heat and energy and this is ultimately why these systems are ineffective.  The foam is the most effective method for reducing heat and energy loss.  It allows us to retain the vital killing temperature for up to 20 times longer.

How much training is needed for teams working with Foamstream?

No formal regulatory training or certification at all is needed so after a half day practical induction session with our expert trainer, your team will be ready to start using Foamstream and the MW-Series straight away.

How do you apply Foamstream?

Foamstream can only be applied via the power lance on the MW-Series systems. Their high level of precision means surrounding vegetation avoids damage whilst allowing access to previously hard to reach edges and cracks. Read more about the technical specification for the MW-Series in our latest brochure.

How many applications are usually required in a season?

Typically, weeds treated with Foamstream require just two to three treatments per season (or as little as one if you’re treating moss and algae) – that means that it delivers the lowest cost of ownership for users. If you were to take foam out of the equation and use a hot water system instead, you would require between five and seven treatments per season and a minimum of two on moss

Where can I buy Foamstream?

Foamstream is available exclusively from Weedingtech and via our approved global network of distributors. Contact us here for details.

Can I just buy the foam?

Sadly not. Because of the need to heat the Foamstream, the MW-Series is vital to the process.  

What type of weather conditions are needed to use Foamstream?

Foamstream can be used in all-weather types (unless it is unfair to ask someone to go outside). This is a big change from traditional spraying and provides our end users with the certainty of knowing when they are going to treat their weeds, allowing for better business planning and improved time management for weed management operatives.

Can Foamstream be used around water courses?

Yes absolutely.  We’ve worked with water companies across Europe where Foamstream has proved itself to be extremely successful in the most sensitive of environments. Find more information here about the benefits of Foamstream for water companies.

Is Weedingtech looking for new distribution partners?

Yes absolutely. We want to be able to offer our technology to as many people as possible.  We’re successfully working with partners in many territories across the globe already, but give us a call if you would like to find out whether there is an opportunity in your region.
