Is waterproofing brick really necessary? There currently are contractors at my kid's school, a 2 story brick building built in 1926. The building is being power washed and then waterproofed. I asked the contractor if the product they are using is safe for plants, animals and children, and he said he didn't know, but would find out. The roof has leaked, but no water had ever come through the brick walls. This seems like a waste of our taxpayer dollars not to mention an environment hazard.
Not knowing the condition of the vapor barrier after 83 years , its an excellent Idea to waterproof the brick;
it will help eliminate the possibility of mold growing behind the brick which is great concern for anyone possibly causing respiratory problems or death in public buildings.
I would almost guarantee water has come thru the brick/mortar at some point during the life of the building, it is why flashing and weep holes are used.
You don't know yet if it is an envornmental hazard?, I would hope the architect would spec something friendly
