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.

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.
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.

Remember, mortar has a 28 day curing time.
Although it is still curing, the mortar repair and re-pointing are getting gradually lighter.
After we knock out the joints, the replacement material will be placed and shaped to create what is known as ribbon pointing. The idea of ribbon pointing is to effectively ‘flatten’ the wall.
the balance that this will create will be surprising and should come up really well. More to come…
