Top 5 Signs You Didn’t Know Were Linked To Mould Contamination

  • Posted by: Alex Wilkie

Mould is not always visible – it can be hidden in not so obvious places such as hidden in wall
cavities and ceiling voids, under and behind heavy furniture or in storage areas that are
infrequently used. But there are other signs apart from visible mould that can indicate you have
a mould issue in your home or office and that you might want to consider further investigation.

Concrete Moisture Testing

What is a concrete moisture test?

A concrete moisture test is used to determine how much moisture is present – usually in order to know if flooring can be safely installed without causing issues. Measuring the moisture of a concrete slab can be done in several ways, but currently the only methods approved by Australian standards measure the relative humidity of the slab. The most common method, uses in-situ probes (ASTM F2170). In this method holes (at least 1 / 100m2) are drilled to a specific depth in the slab, a sleeve is installed into the holes to create a small chamber with an open base inside the slab.  This allows the air inside the chamber to equalise to the relative humidity of the slab. The sleeve is left for a minimum of 1 day for the chamber to equalise with the concrete slab. Following the equalising period, the relative humidity is read using a thermohygrometer or relative humidity sensor.

Mould can have a damaging effect on your home and on the people who live there. If you suspect moisture or mould problems in your home, it’s important to have a professional mould inspection as soon as possible.

Mould often occurs in hidden, hard to reach places, and can build up over time through no fault of your own. In addition to causing serious physical damage to buildings and belongings, mould can also affect the air quality and health of your family.

What is an Air Quality Assessment?

Air quality is often one of those hard things to quantify by ourselves. If your house fills with smoke after burning something on the stove, it’s pretty easy to see the problem and fix it by opening a window or two. But most issues with air quality are much more subtle, often going unnoticed for long periods of time. Poor quality air, like air with high levels of pollutants, carbon dioxide or contaminants like mould can have serious health effects. Studies have found poor air quality can lead to increased rates of asthma, decreased cognitive function and intelligence, and significantly lower academic performance in school kids. This video is a great crash course for what how stale air affects the human body.

Best conditions for drying of concrete slabs

There are four main factors which influence the rate at which a concrete slab dries. These are: time, temperature of material, airflow over material and difference in relative humidity between the slab and the air.  All four of these factors should be controlled in order to effectively dry a concrete slab.

Maintaining ideal temperature and humidity levels inside your home is crucial to your health and happiness. Not only does humidity affect your quality of life, it also affects the quality of your air and your general state of health and well-being. The term”relative humidity” is often used in this context, and refers to the ratio of water vapour relative to the air temperature.
