Moisture Prevention and Mould Prevention

Preventing moisture penetration (and thereby preventing mould growth) in the building envelope is a far better course of action than trying to clean up the damage caused by moisture penetration after the event. Obviously, no one can guard against an unexpected leak from a burst water pipe, or a sudden downpour where water enters the subfloor, but every home owner or property manager can reduce the risk of having moisture contamination in a property by adopting some simple preventative procedures.

Subfloor Moisture Penetration from Garden beds and pathways

Garden beds and pathways that are too close to or higher than an external wall can also lead to moisture build up in the subfloor and also ground water penetration from outside to the subfloor. Try and ensure that garden beds are not hard up against the external wall and if they are, install some kind of barrier between the garden and the wall.

Pathways too close or higher than the base of the external wall can also be an issue as water can either seep (through porous bricks) or flow (via passive vents) under the house.

Passive Vents prevent Water Entering the Subfloor

Fitting passive vents with 'blinkers' will seal them in the event of a sudden downpour and prevent water invading the subfloor. Dampco supplies and installs 'blinkers'. Ventilation is the most important factor in the presence of condensation and therefore mould, followed by heating.

Good Ventilation Helps Prevents Moisture and Mould the Home

All properties require ventilation, internally, in the roof cavity and in the subfloor.

Internal Ventilation for Mould Prevention

Without ventilation, the natural creation of moisture through everyday living - breathing, cooking, heating, cooling - will lead to elevated moisture levels in the property. Check every room of the property and make sure that each one has at least one passive vent in the wall. If not, the property can be exposed to excessive moisture and constant monitoring is required. Any property can have passive vents added to it internally, and in extreme cases, mechanical ventilation systems can be added to forcibly extract moisture from the internal living areas.

Subfloor Ventilation and Moisture Prevention

In the subfloor, the moisture present in the soil will cause long term moisture issues if it is unable to escape from the subfloor via passive vents. In solid brick houses, often just passive vents are not enough to prevent moisture issues and forced air ventilation systems are required. But the more passive vents the better.

Roof Cavity Ventilation is important to Moisture Prevention

Dampco installs both "Eave Vents" and "Whirlygigs" that will very effectively relieve a roof space of moisture build up. These moisture prevention devices help reduce the moisture in the roof cavity and in the long term help prevent mould and damp.

Heating will Eliminate Condensation and assist Mould Prevention

Adding heat to any dwelling will eliminate or reduce the onset of condensation and therefore mould. By raising the core temperature of the dwelling, the internal air will be able to hold more moisture vapour in suspension as it is warm. As the air in the dwelling cools and the dew point is reached, the moisture vapour falls from the internal atmosphere and descends onto the coldest surfaces in the room, forming condensation.

Inspect for Moisture & Damp

  • Thermal imaging cameras detect moisture and danp problems behind walls.
  • Inspection cameras can detect mould and rising damp in areas that may not be accessible.
  • Penetrative and non penetrative moisture metres can detect moisture and damp on wall surfaces and inside wall cavities.

Drying Moisture & Rising Damp

  • Our purpose built trailers are the most powerful drying facilities in Australia.
  • Fast drying is one of the most important equirements for effective mould removal.
  • Large heaters dry out wet sub floor spaces quickly. Our trailer mounted heating units are the fastest drying units in the country.
