We know that every situation is unique, so we tailor our solutions to meet your specific needs, ensuring your waterproofing system is working at its best. If you’ve noticed rust-colored “sludge” appearing in your basement or around plumbing fixtures, it could be a sign that iron bacteria are compromising your waterproofing system, and it’s time for a closer look.

What Are Iron Bacteria?

Iron bacteria are microorganisms that feed on the iron found in groundwater, soil, or plumbing systems. As they oxidize the iron, they produce a slimy, gelatinous substance known as biofilm. Over time, this biofilm can accumulate inside drainage systems, including sump pumps and draintile, leading to clogs and reducing the efficiency of water flow. When this happens, your drainage system may struggle to manage water around your foundation, putting your home at risk of water damage.

How Iron Bacteria Affect Waterproofing and Drainage Systems

• Clogging and Reduced Water Flow: Iron bacteria thrive in environments with high iron levels, like iron-rich soil or groundwater. As the bacteria feed on the iron, they produce sticky slime that coats the inside of drainage pipes. This buildup can cause clogs, slowing down or even blocking water flow entirely. The buildup can also obstruct sump pumps, preventing them from efficiently pumping water away from your basement and foundation.

• Compromised Waterproofing Effectiveness: When your drainage system or sump pump becomes clogged, it can no longer direct water away from your foundation effectively. This results in water pooling around the foundation, creating pressure against the walls and increasing the risk of leaks and potential water damage in the basement. This not only undermines the effectiveness of your waterproofing system but also puts the structural integrity of your home at risk.

• Increased Risk of Corrosion: The slimy biofilm created by iron bacteria can do more than just clog your system-it can also cause corrosion of metal components like pipes, sump pump parts, and even rebar in the foundation. As the combination of iron oxide and slime accelerates deterioration, your waterproofing infrastructure becomes weaker, leading to costly repairs and potential long-term damage.

How to Prevent and Address Iron Bacteria in Waterproofing Systems

• Regular Maintenance: Keeping an eye on your drainage system is key to preventing iron bacteria buildup. Regular inspections and cleaning help ensure the system remains free of slime or rust-colored buildup. If you notice any signs of iron bacteria,

flushing the pipes and clearing any blockages can help maintain water flow and keep your waterproofing system working effectively.

• Waterproofing System Modifications: One way to prevent iron bacteria from taking hold is by installing cleanouts in your waterproofing system. These cleanouts make it easier to access your drainage pipes and sump pump, allowing you to jet out any bacteria buildup before it becomes a problem. Additionally, using non-perforated drainage pipes or modifying your system’s design can help reduce the chances of bacteria buildup by preventing water from being trapped in places where bacteria thrive.

• Water Treatment: If your property has high iron content in the groundwater, installing a water filtration or treatment system can help reduce the excess iron available to iron bacteria. By cutting down on the food source, you can make it harder for the bacteria to grow and form biofilm in your drainage system.

Iron bacteria may seem like a small issue, but their impact on your waterproofing system can be significant. By staying on top of regular maintenance, considering system modifications, and water treatment options, you can prevent iron bacteria buildup and ensure that your drainage system stays efficient.
