Inadequate ventilation can lead to elevated moisture levels in the uncovered underside of your flooring, dampness in the house, and many other structural problems. A sub floor is the crawl space created between the lowest floor and ground of a building. When the space is exposed to high moisture levels, it encourages fungal decay and possible attack by timber-eating insects like termites that are common in damp and moist places.
In October 1993, a study published in the Australian Journal of Public Health on building structural characteristics linked with high indoor air organochlorine termiticides showed that the most common causes for the structural problems are found on the external part of the house and more specifically from the surface and roof water drainage. Technically, all crawl spaces and sub-floors should be viewed as having potential moisture and water problems.
How to Maintain Your Sub Floors Drier
By building and maintaining your sub floors dry along the following lines, you will experience greater success.
Yard drainage- Slope the soils around your house to divert the water away from the house.
Roof drainage- Divert from the house all water coming for your gutters and roof and don't let the roof drainage water to penetrate the soils surrounding the foundation of your home. Your gutter system needs regular cleaning and maintenance for quality functioning.
Hanging tree limbs- If they overhang on your gutters and roof, they can make cleaning and maintenance quite challenging and contribute to more drainage problems.
House construction- During new house construction, the foundation should be sealed carefully. Additionally, install a high quality house perimeter drain system and put separate drainage system for your gutters and downpipes.
To avoid deterioration of your timber floor construction, give good ventilation to the entire sub floor area. The moisture emanating from the ground should be blocked from causing unworthy dampness or deteriorating the building elements further. The law stipulates that, the minimum clearance between the ground surface and the lowest frame of the building should be below 150mm. Also, clearance should comply with any requirement coming from the manufacturer of the materials.
Additional Measures for Keeping Your Sub Floor Dry
Additionally your sub floor will stay dry if you take into account the following measures.
Head room- Large crawl spaces tend to keep drier and allow for extra air circulation besides making maintenance and repair easier.
Venting- Though the benefits of venting your crawl space remains a subject for debate, many of the building codes advocate for some kind of space vents. Air concentration depends majorly on the velocity of wind in any given space hence that must be put into account during construction and management of your sub floor ventilation. People must look into the effects of subfloor-type ventilation and all the preventive measures to help against toxic soil vapors.
Storage- A majority of crawl spaces are too small to be used for any meaningful storage. Also, to store materials and other stuff in will contribute to the reduction of needed air circulation. Such a condition can create an enabling environment for encroachment of rodents and other pests.
