Increase Airflow Under Your House | Rising Damp | Soft Brick Repair

Noticing the presence of mold/ fungus on your walls inside your house, dampness on your cornices and floor coverings such as rugs or carpet? Odds are, whether you are living in an older house or not, if the dampness is located down the bottom of your internal walls or on your floor/ coverings, you are experiencing the effects of rising damp. 

No amount of  additional air movement inside your house will prevent and minimise the effects of rising damp.

From the ground up, you will need to repair soft brick which hold additional moisture, replace and reinstate any defective, soft or missing mortar in between the brick and install a permanent barrier to lower the effects of water rising up the wall and into your floorboards and internal plaster wall linings.

Also, increasing airflow under your house will help to prevent excess amounts of moisture and the consequences encountered. Subfloor ventilation in the way of ‘passive’ air vents or ‘active’ motorised fans can help keep the air moving.

The above photo indicates the process of removing soft brick that is a so commonly experienced from rising damp.

Whilst repointing will help to prevent water ingress into the wall and internal cavity, without replacing soft brick, your wall will still be harbouring moisture. The only way to remove this issue, is to replace the brick. Rendering soft brick can sometimes have a detrimental effect as the mortar used to patch the brick can also harbour moisture if not installed properly.

Efflorescence, subfloor ventilation and rising damp | melbournebrickrepair.com

With salts permeating through this subfloor structure located in Brighton, VIC, it was apparent that there was something very wrong.

subfloor-salt-attack-brighton-melbourne

Efflorescence, aka salt attack is a calcium chloride/ zinc chloride build up caused through moisture in the subfloor or rising damp from subfoundation soil.

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.
