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.

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.
