Understanding Microbial Remediation: Mould Prevention and Treatment
Mould growth is more than just an unsightly problem. It can lead to serious health concerns, including allergens, irritants, and potentially toxic substances. Whether you’re dealing with moisture or specific materials, understanding how mould forms and grows is the first step in proper microbial remediation. In this blog, we break down everything you need to know to address and prevent this common issue, protecting both your home and your health.
What is Mould and Why Does It Grow?
Mould thrives when it finds a suitable environment that offers food, water, a stable temperature, and darkness. When airborne mould spores land on moist surfaces, they can begin to multiply. Among all the factors that encourage mould growth, moisture is the most critical one to control.
To effectively prevent mould, managing the moisture content in your environment is key. Let’s take a closer look at how wet is too wet.
How Wet is Too Wet?
Moisture content (MC) is the measure of how much water is present in a material compared to its dry weight. When the MC exceeds certain thresholds, mould has the perfect environment to thrive. Here’s a breakdown of the levels:
- 30% MC – Wet rot begins to form.
- 20% MC – Mould growth accelerates rapidly, particularly species like Stachybotrys chartarum, which can lead to wood-destroying fungi such as “dry rot.”
- 16% MC – This is the lower limit of moisture that supports mould growth. If moisture can be kept below this threshold, mould cannot flourish.
Monitoring moisture levels is critical for preventing mould. But how fast does it grow once conditions are right?
How Fast Does Mould Grow?
Mould can grow and become a major problem in just 48-72 hours! Two of the most common mould types found in buildings—Penicillium and Aspergillus—can colonise in this short time. Once they take hold, their spores can become airborne and inhaled, posing respiratory risks. Although these moulds can grow in low moisture environments, they still need at least 16% moisture content to thrive.
What’s the Best Way to Prevent Mould Growth?
The best way to stop mould in its tracks is to remove moisture quickly. Whether it’s floodwater or condensation, drying materials as fast as possible is key. For large-scale moisture removal, professionals often use equipment like the Dri-Eaz LGR 7000XLi dehumidifiers and the Velo Pro airmover to reduce humidity levels and remove bulk water.
By ensuring a rapid and efficient drying process, you can dramatically reduce the chance of mould growth. However, if you’re ready to dive deeper into understanding microbial remediation, we have a solution for you.
