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.

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.
