The humid climate in Sydney is just one factor that can lead to rising damp problems. But there are solutions to this problem!
A sub-floor ventilation system stops this problem at the core. It combines ducting, fans, times and vents to help create adequate ventilation that pulls in fresh air and pushes out old, damp air. A sub-floor ventilation system aids the flow of air underneath your home. This airflow will help eradicate the existence of moisture in your sub-floor area, which will then prevent the build up of mould inside your home.
The essential principle behind sub-floor ventilation systems is to achieve a cross flow of ventilation in this area through the use of a fan. The fan pulls moist air from your sub-floor and pushes it outside. Passive vents also help achieve this cross flow of air. Passive vents are positioned to ensure only fresh air enters your sub-floor area. Without these vents, your sub-floor area will be filled with stagnant and damp air. This then leads to moisture build up.
It is also important to note that sub-floor ventilation obstructions, such as soil piles, walls or sloping earth, will hinder your chances of achieving adequate cross flow ventilation. Sub-floor ventilation systems, especially fans and vents, help move the air around. This keeps your sub-floor area well ventilated, fresh and most importantly, free of damp!
