Today, the method generally used to address land pollutants is to excavate and remove the polluted land, which is then treated or transported to a landfill at another location.
As a rule, these are costly methods that result in a heavy environmental load,
due to long transport distances, among other factors.
It is in such situations that the patented Ecosoil method can become a very simple and economically sound alternative.
The Ecosoil method enables on-site treatment of hazardous substances. This is what makes the method so simple and economical.
It is particularly suitable for the treatment of large areas of polluted land. It is also appropriate for preventive applications.
In such cases, the obstacle strings are laid in crisscross patterns beneath or beside the object to be protected, or which is exposed to emission-related risks.

| A number of horizontal holes are bored in the land to be treated,
with the help of well-known technology known as controlled horizontal boring.
A number of such holes are drilled parallel to each other. Subsequently,
holes are also bored in an opposite direction beneath the initial level, in order to completely cover the land being treated.
The distance between the holes is approximately two meters depending on the degree of contamination. A pipe with slits or perforations is then inserted in the bored holes.
Appropriate biosorbants, such as zeolites and/or polonite, contained in holders joined by a wire, are drawn into the pipe, where they then remain.
The resulting absorption takes place with the help of the moisture of the subsoil,
which is normally sufficient to achieve the desired effect.
If necessary, water may be added to provide moisture to the bored holes.
When the strings of absorbents have been under the land for a period of time sufficient to attain the desired absorption or decontamination effect,
the wire and the connected holders are removed from the bored hole and the used absorbents can be regenerated for use in the decontamination of other areas.
Facts about Ecosoil
- The method is designed for on-site treatment of contaminated land.
The method is appropriate for areas in which there are large amounts of contaminated land.
The treatment process can take a long time (longer than six months) and is suitable for
cases where the excavation and removal of the polluted land is not an option for financial reasons.
- Following a long period in operation, excellent results are achieved, particularly in terms of heavy metals, such as cadmium.
