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.

All clay bricks will deteriorate. This is inevitable. And as such, maintenance of your brick house cladding will be ongoing into the future. Stay on top of it and contact melbournebrickrepair.com for further information.

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.

melbourne-brick-repair-subfloor-ventilation

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.

Edwardian Brick: Rising Damp and Silicone Injection | Damp Course Installation Melbourne

As a result of drilling and silicone injection having been previously used on the above Edwardian brick heritage property, located in the Melbourne suburb of Flemington, the failure of the process is evident in that, rising damp has still occurred despite the previous owner’s intent in trying to fix the issue.

rising-damp-repair-fail-melbourne

Salt build-up behind the injected silicone is a very common result of injection which could have been avoided.

Despite the effort in trying to stop the moisture, the buildings previous owner was only trying to do what was right. The fact is that silicone injection seldomly works. It is really only for walls over 2 foot thick. It is certainly not for a heritage double brick structure. Discolouration, as seen above, affects both mortars joint and brick alike; hastening deterioration of both.

Visible deterioration of the mortar joint has occurred above the drill lines from chemical dampproofing.

By using a physical barrier instead, this wouldn’t have occurred. Rising damp is a very hard thing to prevent altogether. In all actuality, every masonry structure will encounter some form of moisture transferral from the clay sub-found material. In the case that physical barriers are installed, the decay of mortar and brick is slowed dramatically. By also increasing airflow under the floor, you are also providing a good natural method of easing rising damp.

From Old to New Again, Try our VIC Bluestone Restoration Service | MelbourneBrickRepair.com

When our client first contacted us, the facade of the circa 1860 cottage located in Western Victoria had never seen a traditional restoration. In over 150 years, weathering and general deterioration of the mortar jointing, also known as pointing, was highly evident.

Before Restoration, the c.1860 Bluestone Cottage in Western VIC was run down with most of the Mortar Jointing missing

Although the stone was in very good condition and with clear indication that it was very well built,  mortar repair and repointing was integral in rejuvenating the old bluestone structure.

The client was extremely happy with their new entrance. The repointing method used was traditional ribbon pointing and it lasts for a very long time.

Here is a before and after of another aspect of the same building. A massive improvement.
