With salts permeating through this subfloor structure located in Brighton, VIC, it was apparent that there was something very wrong.
When viewed from behind the wall, the salt attack was much worse; formations of hygroscopic gel and rust was evident.
Through constant hygroscopic moisture (airborne) contained in the subfloor area, and the lack of ventilation, the damage to the bricks is inevitable.
Ideally, repairs should occur at a time prior to the state of deterioration as indicated.
