BioSealing is a new technology for sealing underground leaks, for example in dams, dikes and tunnels. Nutrients are injected into the soil near to a suspected leak, stimulating the growth of soil bacteria. This drastically reduces the permeability of the soil, gradually sealing the leak. BioSealing is a sustainable and cheap alternative to traditional methods, such as grouting or chemical injection, for sealing leaks on site. Deltares supplied the know-how and a number of companies who saw the market potential were prepared to invest in the system and test it.

Laboratorium Utrecht

The BioSealing Joint Industry Project will be performed in the period 2014-2015 to answer the latest research questions relating to the technology. On the basis of laboratory tests and practical cases (e.g. in the Czech Republic), the project will study possible improvements. Once this research has been completed, it will be time for a major market launch for the new technology.

The parties involved in the BioSealing JIP are: Sireg (Italy), Agrana Research and Innovation center (Austria), BioClear (Netherlands), Texplor (Benelux),  Avebe (Netherlands), Züblin Spezialtiefbau (Austria), Volker Staal en Funderingen (VSF) (Netherlands), GEOtest (Czech Republic) and Deltares (Netherlands).
