The proven alternative
Hot foam weed control. Proven, chemical-free, and ready to work.
The science is simple. The results are consistent. Here's why hot foam has become the global standard for herbicide-free grounds management.
Independently tested. Academically validated.
We're not asking you to take our word for it. Take theirs.
Hot foam has been independently validated in academic trials and trusted in the world's most demanding green spaces. Studies from the University of Pisa and the Agricultural University of Athens found it highly effective, with results comparable to glyphosate in controlled testing — and wider research ranks hot foam as the most effective of the non-chemical thermal methods, ahead of flame, steam and hot air. Nothing leaches into the soil, water or air, and no residue is left behind for people, pets or wildlife.
Foam holds the heat where hot water loses it
Peer-reviewed trials show adding foam to hot water lowers the water dose required by at least 2.5-fold — because the foam keeps lethal temperature on the leaf and root for longer than water, steam or hot air alone (Martelloni et al., 2019 & 2021).
Matched glyphosate — without a single chemical
In independent trials, hot foam has matched glyphosate's results, including on some of the most stubborn invasive weeds, with nothing going into the ground.
Nothing left behind
Nothing leaches into the soil, the water or the air, and no residue is left for people, pets or wildlife — just clean ground and a weed population that shrinks season on season.
"Hot foam reduced weed biomass by up to 81%, 88%, 90% and 96% compared to mulching, mowing, pelargonic acid and the untreated control."
"Hot foam and glyphosate resulted in the lowest NDVI and weed biomass."
"Adding foam to hot water made it possible to lower the required dose of water by at least 2.5-fold compared to hot water used alone."
"Hot foam applications represent a new, smart concept in the area of thermal weed control."
Peer-reviewed
Studied by the Agricultural University of Athens, the University of Pisa and others — published in the peer-reviewed literature since 2016.
Benchmarked against glyphosate
Directly compared with glyphosate, hot water, mowing, mulching and pelargonic acid — matching or beating the alternatives on biomass reduction and regrowth.
Proven in the field
Trialled in vineyards, olive groves, public parks and Swedish municipal spaces — the settings that matter for councils, estates and contractors.
Hot foam is a mature, evidence-backed method of thermal weed control — not a novelty, not a workaround, and not an experiment on your site.

The direction of travel is already set
This isn't a future risk. It's already in the contracts.
More than 80 UK local authorities have introduced restrictions or moratoria on glyphosate use on public land, and the number rises each year. Across Europe, national bans on non-professional and municipal use have been in force for years — France prohibited chemical weed control on public green spaces from 2017, and others have followed.
Herbicide-free clauses are now standard in an increasing share of grounds maintenance tenders. The organisations that move first hold the advantage.
How it works
A hot, insulating blanket that reaches the crown of the plant.
Water is heated on board and combined with a biodegradable, plant-based foam. When applied, the foam clings to the leaf and holds thermal energy in place long enough to rupture cell walls and destroy the growing point — including the root crown that hot water and steam alone can miss.
The foam itself breaks down within minutes, leaves no residue and enters the soil as nothing more than water. There is no chemical, no drift, no waiting period.
Why foam works better
Foam holds the heat where hot water alone loses it.
Extended contact time
Foam maintains lethal temperature on the leaf and crown far longer than water alone.
Root-level kill
Independent studies confirm equivalent or superior kill compared to glyphosate.
No off-target damage
The foam sits where it's placed. No drift, no run-off, no collateral.
Zero residue
Plant-based, biodegradable, breaks down in minutes. Water is the only trace.
