PuriSoil®, a proven, cost-effective technology
 

PuriSoil® is an eco-friendly technology. At the site that has to be cleaned up pipes are inserted in the ground to a depth lower than the contaminated layer of soil. Air is then injected into the soil through the pipes. A specially developed bio-active material (PuriSoil starter) is mixed with the top layer of soil. As the air flows upwards through the soil it carries the contaminants to the surface. In this bio-active zone the pollution is completely and very effectively broken down and converted into CO2 and water. 		  

 

 

 

 

 

 
   

Minimum pain, maximum gain
 

Quick result

Inserting the pipes in the ground takes no time at all and causes scarcely any disruption. The air can be injected at high pressure with a compressor. Consequently, large areas can be cleaned quickly. There is no need for a separate contaminants-removal process since the contaminants are treated and converted to water and CO2 as an integral part of the remediation process in the subsoil. Soil remediation with PuriSoil is quick, ecologically friendly and causes scarcely any damage to the local environment.

Customized solutions

At the start of the project and throughout the remediation process specialists take extensive samples and measurements. They supervise the remediation from the initial soil survey to the handing over of clean ground, all the while remaining in close contact with all parties involved.
