If nothing is finished this will encourage termites. When a sub-floor is inspected and it's apparent that the bottom is discoloured (by wetness) from other components and the presence of mycelia (fungi), this is a visual sign that moisture is discovering its way into the sub-flooring area.
If a sub-ground ventilation system is drawing the humidity (damp air) out, air circulate will journey from the purpose of least resistance. So if a passive is in shut proximity to a fan-compelled sub-floor ventilation system supply air would be drawn by way of the passive vent and out by way of the fan-pressured sub-floor air flow system. Sub-flooring ventilation techniques placement is necessary that's the reason it is very important get professional recommendation from respected folks. I have been putting it off to crawl beneath the home for a while. The moisture problem was so dangerous; I really did not need to find out for some time, particularly with steel frame development.

Thanks once more. Envirofan’s leading edge design principle is to maximise sub-flooring ventilation with out obstructions. In seventy per cent of instances our objective is to minimise the usage of versatile ducting and in-line fan techniques where the trail of air is disrupted.

When timbers attain a moisture content of 20% decay fungi can develop which causes the timbers to rot and might result in complete failure and collapse of the timber flooring.
So source of water identified and rectified – now to the sub-ground air flow. Obviously we needed to discover and fix the supply of the water, then improve sub-flooring air flow. We purchased a double brick home that had some moisture underneath the ground, with a nasty musty scent creating in the bedroom.
