What is the effect of the hot water of the WAVE on the plant?
One of nature’s best energy sources is (surface) water, which the WAVE machine efficiently makes use of. By spraying hot water with a temperature of 98 degrees Celsius (no steam) directly onto the plant a large amount of energy is transferred into the plant. This results in the destruction of the cell structure of the plant. The big advantage of using hot water is that it runs down the gaps between the stones and thus easily reaches the roots (water flows downwards by nature) After the treatment(s) the roots of the weed have been exhausted to such an extent that the growth stops, resulting in a paved surface that is weed-free.
Is de WAVE CO2 neutral?
Yes, every WAVE machine is CO2 neutral. The WAVE machines run on diesel, which means they emit CO2 when being operated. Since WAVE B.V. values sustainability and environment very highly, we compensate the CO2 emissions by working together with the organization Treesfortravel, which plants extra trees in order to compensate for the CO2 emissions of all operational WAVE machines. More information on the organization Treesfortravel.
Does the WAVE do damage to streets and other hard surfaces?
No, the WAVE method does not do damage to the surface. The WAVE machine operates with a low pressure of 2.5 bar (comparable to the water pressure on the kitchen tap) and does not apply high pressure injection. Due to the low pressure the sand in the gaps between the paving elements remains in place. This is a big advantage over other methods of weed control, like those operating with brushes. Using the WAVE means less damage and thus lower maintenance expenses for these hard surfaces.
Can the WAVE also be used on semi-hard surfaces?
Yes, the WAVE is perfectly suitable for semi-hard surfaces. Due to its low tyre pressure the WAVE machine does not leave any traces on semi-hard surfaces. The machine can operate accurately along lawns and flowerbeds.
Can the WAVE also be used on the pavement?
Yes, the WAVE machine has a maximum width of 1.25 m (a front tank, width 1.60 or 1.20, easy to adjust)) and is thus perfectly suitable for weed control on the pavement. The pressure of the tyres on the pavement is comparable to that of a big lawnmower. The shiftable.front tank gives the operator extra scope to get to spots that are difficult to reach.
Apart from on weeds, can the WAVE also be used on algae and different kinds of moss?
Yes, the WAVE method is effective with regard to all plants, all kinds of grass, moss and algae since the WAVE destroys their cell structure. That is also the reason why the Wave (in contrast with the chemical methods) does not have the problem of resistent weeds.
Are there any kinds of weeds that are resistent to the WAVE?
No, every plant can be scalded. Thermal weed control has the same effect on all plants. This is in contrast with chemical methods of weed control where plants have shown a growing resistance to the active agent (frequently glyphosate).
Although there are no weeds that are resistent to the WAVE, there are some perennials (dandelion, horsetail, etc.) which make different methods of weed control more difficult. The reason for that is that perennial weeds often have an extensive root system and have built up enough reserves to allow fast regrowth. Despite the fact that these kinds of weeds pose difficulties for all methods of weed control, several treatments with the WAVE are sufficient to exhaust the plant.
How often do you have to use the WAVE?
This depends on the desired result, the weather and the extent of growth at the start of the treatment. Many local councils have agreements on visual quality. There are different levels of visual quality with regard to the amount of weed tolerated in a certain area or community. In most cases three to four times per weed season (March to October) are sufficient.
Do you have to sweep after the WAVE treatment?
No, after having been treated with the WAVE the parts of the weed which are above the ground die within a few days. The plant wilts and no sweeping is required. In case the WAVE is used for the first time in a neglected or poorly maintained area (extent of weed growth), our advice is to have a preliminary run first.
Is the WAVE expensive (compared to other methods of weed control)?
Comparative study has shown that the WAVE method is not the cheapest method of weed control (that is the use of chemicals). However, the same study has shown that the WAVE is the most effective and environmentally-friendly method in weed control. As opposed to other methods of weed control the WAVE can reduce the level of weedgrowth instead of just controlling it. TOOL LINK STUDY KRISTOFFERSON ( see downloads).
Since the WAVE does not do damage to the (semi-) hard surfaces, there will be savings on the maintenance of these surfaces in the long run. Therefore the added value and advantages of the WAVE are not only related to the high quality standard of weed control but also to the environmentally-friendly and sustainable way in which it is carried out.
Can I walk on the pavement directly after the WAVE treatment without getting burns?
Yes, the reason being that the WAVE does not heat up the hard surfaces to such an extent that there is the risk of blisters. Besides, the machine does not spray unless weed is detected. These minimal amounts of water prevent the forming of puddles of hot water on the hard surfaces.
Does the WAVE use tap water?
No, the WAVE machine does not need tap water. The reason for that is that the machine has different water filters so that the machine can also perfectly function with surface water.
Can the WAVE tackle weed in the gutter / right along the wall/ under obstacles?
The WAVE machine has a shiftable front tank, which the operator can control in order to expand the range of the WAVE, if necessary. Besides, the front tank has sprayers on both sides so that weeds along the gutter and under obstacles can be treated. In case these options are not sufficient to achieve the desired result, the operator can decide to treat spots which are not easily accessible manually with the standard hand lance.
Can the WAVE operate along lawns?
Yes, the WAVE can operate along lawns. As long as the front tank is above hard surfaces the grass of the lawn itself is not detected. Therefore the Wave makes a very accurate transition between lawn and hard surface possible.
Can the WAVE also operate among the plants?
No, the WAVE is not suitable for working in the borders. However, that can be done with our mid series.
Can the WAVE also clean artificial grass?
Hot water can be used to get rid of ingrowing weeds. Yet, the pressure of the WAVE machine is too low to break down unwanted layers in the soil.
Can I buy and/or hire the WAVE?
Both options are possible, ask for the options: info@waveweedcontrol.eu or phone: 0031318-469 799.
How does the LCA-analysis work?
Life Cycle Assessment (LCA), also called life cycle analysis, is a standardized international method which has assessed the impact of the WAVE machine on the environment throughout its whole life cycle. The method, which is repeated after some years, is very suitable for a comparative assessment in order to monitor the progress. The disadvantage of the LCA analysis in the Netherlands is that the manufacturers can supply data without screening as a result of which unreliable data are compared with each other.
Does the WAVE always apply the same amount of water onto the plant?
Yes, the WAVE has infrared sensors. These sensors ensure that the WAVE does not release any water unless weeds are detected. When weeds are detected, the adequate amount of water is assessed by the sensors and is – irrespective of speed - controlled by the computer which calculates the speed and measures out the right amount of water.

WAVE. All things considered, the best in weed control
