How can masonry be extended?
- Metal connector plate (or 'wall starter system') bolted to the existing wall and metal wall ties tie in the new wall at appropriate intervals - advantageous as it is quick, easy and best used if the old brickwork is of a different size/colour to the new
- Tooth-in new brick work with the existing brickwork - consider colour matching (may need to try and conceal the join behind a rainwater pipe or set the new wall back from the face of the existing to provide a shadow gap)
