Ferrous Iron || Ferrous Iron and bacteria problems

Ferrous iron

Ferrous iron is a natural phenomenon resulting from bacteria activity of soils rich in iron such as sandy soils. In the presence of water and oxygen, a ferruginous bacteria transforms water’s soluble iron to insoluble iron. The result of this transformation produces an orange viscous mud, composed of water, fine particles of soil, insoluble iron and bacterial residues. Orange viscous sludge produced during this reaction, adheres to the interior and exterior of the French drain, thus obstructing the perforations which normally allow the water to move and evacuate through the drain. Once the drainage system is blocked, hydrostatic pressures are created and infiltrations occur, while creating significant damage to the basement of the building. Iron ochre causes are not yet well understood. It is very important to hire a qualified company for the analysis, inspection, cleaning of your French drains. A qualified company can make an appropriate diagnosis using fine technology tools such as colour cameras to inspect your French drains.

Here are the cities where we have seen problems with iron ochre: Blainville, Joliette, L’Assomption, Lachenaie, Laval, Laplaine, Lorraine, Mascouche, Otterburn Park, St-Adèle, St-Amable, St-Colomban, St – Jerome, St-Lazare, Sainte-Marthe-sur-le-Lac, Terrebonne and Vaudreuil-Dorion.
