One of nature’s best energy carriers is (surface) water. The WAVE machine makes efficient use of this. Spraying water at a temperature of 98 degrees (not steam) straight onto the plant means that a large quantity of energy is directed at the plant. This results in the cellular structure of the plant being destroyed. The major advantage of hot water is that it falls through the stones and so reaches the roots as well (water by its nature soaks down). Following the treatment(s) the weed’s roots are so exhausted that growth comes to a halt, with the result of a weed-free road surface.
Yes, the WAVE service and company vehicles are compensated for CO2 emissions. In addition, all active sensor-guided WAVE machines in the Netherlands are CO2-neutral. As WAVE sets great store by operating sustainably and by the environment, we compensate for these CO2 emissions. We do this in cooperation with the organisation Treesforall. This organisation plants more trees to compensate for the CO2 emissions of all operational sensor-guided WAVE machines. For further information on this organisation, which is active in the retention of woodland and the stimulation of local economies, see Treesforall.
No, the WAVE method causes no damage to the subsoil. The WAVE machine operates at a low pressure of 2.5 bar (comparable to the water pressure from a kitchen tap) and does not use high-pressure injection. The low pressure means that the sand in the joints simply remains in place. This is a major advantage by comparison with other weed killing methods, which use brushes for instance. Working with WAVE means less damage and so lower maintenance costs for these paved surfaces.
Yes, WAVE can certainly be used on semi-paved surfaces. As it has a low wheel pressure, the WAVE machine leaves no tracks on a semi-paved surface. Moreover, small stones and grit are not thrown up. This prevents damage to the surroundings and means that the semi-paved surface does not need re-profiling afterwards.
Yes, with its maximum width of 1.25 metres, the WAVE machine is definitely able to control weeds on the pavement (easily adjustable front end of width 1.60 or 1.20 metres). The pressure exerted by the tyres on the pavement is comparable to a large lawnmower. The swivelling front end allows the driver additional options for gaining access to places that are difficult to reach. The machine is able to work accurately along lawns and plant beds.
Yes, the WAVE method works an all types of plant, grass, moss and algae. WAVE destroys the cellular structure of these varieties, simply by the energy in the hot water. For this reason, no weeds are resistant to WAVE; by contrast to chemical methods of weed control.
No, any weed can be cooked, even stubborn weeds. Thermal weed control works the same way on all plants. This is in contrast to chemical weed control methods, where there is increasing evidence that plants become resistant to the active substance (frequently glyphosate).
Even stubborn weeds with a strong root structure, such as dandelions, horsetail, etc are effectively controlled with the WAVE method. For these, several treatments will probably be necessary, as the root structure has built up reserves and reaches deeper into the ground. At every treatment with the hot water of the WAVE machine, the root structure becomes more exhausted until the weed no longer returns.
This depends on the result desired (appearance specified), the weather and the extent of weed growth at the outset. Many local authorities reach firm agreements on the appearance or the extent to which public areas have to be weed-free. There are different levels of appearance with respect to how much weed growth is tolerated in an area or district. In virtually all cases, three to four weed control treatments per season (March to October) are sufficient.
No, following the WAVE weed treatment, the parts of the plant above ground die off after a few days. The plant shrivels and does not need to be swept up. If WAVE is being used for the first time in an overdue or poorly maintained area (degree of weed cover), we advise conducting a preliminary round.
Comparative research reveals that the WAVE method is not the cheapest weed control method (chemical weed control is cheaper). But the same research shows that WAVE is certainly the most effective and environmentally friendly method of controlling weeds. By contrast with other weed control methods, WAVE is able to suppress the weed level instead of merely controlling it. WAVE is certainly a cheap method over the long term, as the weed pressure declines and less weed control then has to be done.
As WAVE does not damage paved or semi-paved surfaces, costs are saved moreover on repair work to these surfaces. WAVE’s added value lies not only in the fact that it provides qualitatively good weed control, but also that this is done in the most environmentally friendly and sustainable way.
Yes you are, as the WAVE machine does not heat the paved surfaces to the extent that there is a danger of burns. Moreover, the machine sprays only if weeds are detected. As the amount of water is minimal, no puddles of hot water are left on the paved surfaces.
No, the WAVE machine does not have to be filled up with tap water. The machine has various water filters that ensure that it operates optimally with surface water as well.
The WAVE machine has a moveable front end. The driver can steer it at will to extend the reach of WAVE. The front end also has sprayers on both sides. Using these sprayers, weeds can easily be controlled along the gutter and under obstacles. If these options are insufficient to achieve the desired result, the driver can opt to treat the inaccessible places manually with the standard hand-held lance.
Yes, WAVE can operate right alongside lawns. As long as the front end goes over the paved surface, the lawn grass will not be detected. For this reason WAVE is able to effect an extremely accurate transition from lawn to paved surface.
No, the self-propelled WAVE machine is not suited to operation in plant borders. But the Mid Series manual machine can certainly do this.
The hot water controls ingrown weeds. The pressure of the WAVE machine is too low to break down disruptive layers in the structure.

The WAVE machine has been analysed using Life Cycle Assessment (LCA). This is a standardised international method that calculates the environmental impact of a machine or method over its entire life cycle. The method is well suited for repetition after a number of years. WAVE can derive a good comparison from it to monitor improvements. The disadvantage of the LCA-analyse in the Netherlands is that manufacturers can supply unscreened data. This means that unreliable data may on occasion be mutually compared. Outcomes from comparative LCA analyses are for this reason not suitable as a commercial argument.
Yes, WAVE works with infrared sensors. These sensors ensure that WAVE sprays water only when weeds are detected. The valves linked to the sensor are activated proportionally independently of the speed. This means that the speed WAVE travels at makes no difference. The software calculates the speed and doses the right quantity of water.
