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.

Physical Removal of Mould is Key

Current mould remediation guidelines state that physical removal of mould should be the normal course of action, and that use of chemicals to kill mould is NOT recommended.
