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.

Instead of reinventing the wheel, we have revived an old design and added to it.
Bluestone, also known as Basalt, is an extremely versatile construction material. Traditionally, it has been utilised as a paving material and also extensively in aggregate form contained in modern concrete mixes.
Knowing that Basalt has more to offer than just being used as an aggregate, the STONE BRICK™ Architectural Cladding System will impress even the most avid critic .

Is your house cracking up? Made it through winter and now you want to get the house airtight and weatherproof? You may need crack injection and/ or brick stitching.
Cracking at mitre corners is very common in masonry. Fix it with brick stitching.
First, the mortar material in between the bricks should be removed. This will provide longer serving results for the repair. Next, the joints are lined with the steel reinforcement. These elements are either galvanised or stainless steel.
The stitches are installed as regularly as required.
With the brick stitches in, next is the final tamp point.
Replacement mortar is reinstated, making the repair complete.
Raised Ribbon Pointing replacing older Brick Tuck Pointing on Ballarat Heritage Facade
When comparing traditional ribbon pointing as opposed to brick tuckpointing there are several differentiating factors.
As you can see from the above photo, the heavy oxide mix used on brick tuckpointing (top courses) can actually cause issues if not installed correctly. Mortar, often used in only one colour, is used to smear over the original bedding mortar which is visable where the red coloured mortar has fallen off. This is due to the smear coat method only being several millimetres thick or possibly too brittle to start with. In the instance above, this is definitely the case.
Another issue is that due to oxides’ cementitious effect on the mortar matrix, the mix can often be quite destructive to the 80-100 year old brick. Mortar, as also evident above, is smeared over the brick arris; partially covering the face. In tension, this can snap corners off and even break bricks clean in half–especially old, soft brick.
The biggest comparison, besides appearance, is that the traditional ribbon technique will protect the brick, whilst at the same time, provide depth and definition to the masonry facade. Standard tuckpoint can last quite a while but as opposed to the deeper ribbon pointing, the facade will age better and can last a lot longer.

Some bricks are notoriously hard to replace, we can help.
Replacement of mortar jointing has more than just an aesthetic benefit. Whilst it does improve the general appearance, it also serves to strengthen the overall structure by filling voids caused by differential settlement.
