How a Damp Subfloor Impacts Your Home
What is a subfloor? Also known as a crawlspace, a subfloor is a narrow, unfinished area beneath a building, providing access to plumbing, wiring, and ventilation while allowing limited space for maintenance. A raised floor is suspended on bearers and joists, the space between the timber floor and the earth is the subfloor. The subfloor space facilitates upkeep and repairs without extensive excavation or structural alterations. Sometimes water can collect in the subfloor cavity due to issues such as rainwater ingress or leaking pipes. This may cause the following issues:

Warping Floorboards
A damp subfloor causes moisture absorption in floorboards, leading to warping and structural damage over time.

Water Damaged Structural Timbers
A damp subfloor may cause wood rot in structural timbers, compromising stability and structural integrity over time.

Mould Growth & Dissemination
A damp subfloor fosters mould growth, spreading spores throughout the home, potentially leading to health issues.

Termite Infestation
Rotting wood in the subfloor attracts termites, increasing the risk of infestation and structural damage to the home.
How a Damp Subfloor affects your indoor air quality

1. SUB-FLOOR AREA
A raised floor is supported by bearers and joists. The subfloor is the space between the floor and the earth.

2. water Ingress
Rainwater, leaky pipes, a saturated water table or poor drainage may cause water to collect in the subfloor area.

3. Mould Grows
Moisture may cause mould to grow on the topsoil, structural timbers and the underside of the floorboards.

4. Mould Spreads
Mould spores infiltrate through the cracks in the floorboards and contaminate the living space.

The Solution? Subfloor Ventilation
A subfloor ventilation system is essential for managing airflow in the subfloor beneath your suspended timber flooring. It is comprised of vents, inline exhaust fans, and a ducting system. It facilitates air exchange between the subfloor and the external environment. It regulates moisture levels, this may help prevent mould, wood rot, and structural decay, while enhancing indoor air quality. The inclusion of an inline exhaust fan and a ducting system with strategically placed suction points addresses dead spots, ensuring comprehensive airflow distribution and effective moisture control.
Types of Subfloor Ventilation Systems?
Three methods of ventilation can be deployed:
- Negative pressure ventilation is suitable for most homes. This method extracts air from the subfloor, creating a vacuum to draw in fresh air.
- Positive pressure ventilation pushes outside air into the subfloor, displacing stagnant air. This method can be deployed to dry out wet spots in the subfloor. However, this method must be used with extreme caution because positive pressure can force mould spores into the living space of the home.
- Balanced ventilation ensures that there is equal volume of supply and exhaust air, maintaining optimal airflow without excessive pressure differences.
