Historic Brickwork Paper 6

[AgMechEngr]

I am involved in a project that is repurposing an early 1900s warehouse that will include multiple new openings for windows and doors. Does anyone have Dik's historic brickwork paper that I believe used to be hosted on SRE's website?

Thank you, Dik.

I've seen so much masonry repair done badly that I wrote a little paper about 30 years back to let clients know some of the pitfalls. There were so many buildings in Toronto where they had used sandblasting to clean and removed the fireskin in the process. It started out as a two page Appendix, added to reports and has grown, over the years. Glad to be of help...

The owner of the building has mentioned pressure washing before construction; aggressive techniques are still in fashion.

It depends on the type of brick and mortar, realising that damage to the outer surface is cumulative, once it's done. It doesn't stop at that point. It's very difficult to go back. I've seen a lot of damage caused by improper 'cleaning' and re-pointing... the worst caused by sandblasting and re-pointing using improper mortar. You need to research and contact cleaning agencies that specialise in cleaning historic masonry. To do it properly it's not easy and can be costly.

Can the client live with the 'patina' of 'ancient' brickwork? In some circles, it can be attractive. Is there a local architect that can offer an opinion? Is there an 'out of the way' area that can be used for a 'test'?

I stepped away from the project after discussions with the contractor. They ultimately just wanted a stamp for permits without paying for engineering.

The paper is a great guide and I will continue to reference it. I am looking to move more into historic renovations/preservation projects anyway. It is fascinating stuff.

I found it fascinating stuff. I'd seen a lot of masonry buildings in Toronto deteriorating because the fireskin was abraded off with sandblasting. I was asked to look into a building that needed remediation (due to water damage) and the client wanted to 'clean it up' in the process. The company I was working for at the time was located at King and John and they had sandblasted the face of it and the structure was continuing to deteriorate. It's then I wrote a little 'blurb' to let owners know that any remedial work be done with care. I did a lot of work on historic brick and brown rot deterioration back then... and only occasionally run into issues, now.

You can give the contractor/owner a copy of my article... there's a really good chance of them 'screwing up' another brick building.

@dik: How many of these little papers do you have kicking around? I think it's fascinating. I do a similar thing in my practice and it's both interesting and really good to maintain competence/consistence/quality.

I'm not sure... likely half a dozen or a dozen... It's just a matter of digging them up. I do them for specific tasks to assist the client/ or some other engineer... Most of them started out to be included in appendices to reports.

The historic brickwork started out as a page and a half... and over the decades, it has been transformed. As I get added information, it gets added to the end to be incorporated into the main body of the paper, at some later time.

I have them for SOG construction, dry-rot (aka brown rot), and a few other items... I've posted versions of the SOG and dry-rot papers, here in past. I seem to recall doing them for concrete testing, placing and inspection for remote projects... and a bunch of other stuff.

Dik, I really enjoyed the write up. Thank you so much. I do a lot of work on brick rowhomes and this paper gives excellent commentary on some of the things I've seen.

If it's not too much trouble to direct me, I would be very grateful to read the SOG paper.

Attached... they are all works in progress...
