Stephanie,

I haven't heard of a great solution to this issue with brick that works in all instances. It's not only the moisture and erosion of the surface but you can also get salt efflorescence in historic brick as well. Often it takes some scientific analysis to really define the problems with architectural materials. Just using a consolidant without looking deeper at the issue and the options could make things worse.

I'd suggest contacting the architectural conservator at Colonial Williamsburg (757-229-1000 - ask for the architectural conservator's extension) and ask them if they have suggestions. More than likely you'll need an architectural conservator as a consultant.

Cheers!

We have an early 1900s brick building that is deteriorating at a fairly rapid pace. We spoke with our State Preservation Office and they came out and did an assessment on the building. It was concluded that the bricks used to construct the building were under-fired and therefore more susceptible to moisture, which is causing them to is crumble. It was suggested to do a consolidation treatment, but a test run of the product did not yield the results we were hoping for. I was wondering if anyone else has had this issue and if they found a good solution to the problem. Thanks for any help!
