WARRANTY

The treatment, which is covered by a warranty, restores the function of the footing (French) drain. Ferrobacteria will no more create an obstacle to the good performance of the footing drain for the determined duration of the maintenance contract.

We guarantee that the soil treated by us will not be contaminated by a chemical solution or chemicals. Our treatment will thus not alter the quality of underground water. 

Gas

The gas results from the use of our equipment that extracts nitrogen from the air. The gas then obtained is catalyzed to produce a reactant and unstable gas which is injected in the footing drain. Once this gas has lost its active power, it recovers its status as a non-harmful essential element of the air.
