Dampproofing the cavity face
A number of buildings being designed these days call for dampproofing on the cavity side of concrete masonry backup walls. In addition to the dampproofing, vents often are added to the top and bottom of the walls. The dampproofing and vents can add quite a bit of cost to the wall system. We have designed many buildings with a 14-inch cavity wall system without dampproofing or vents. To date, we are not aware of any problems with this type of construction. What has prompted this change in design? What are the pros and cons of dampproofing and venting?
Stopping Rainwater Penetration
Walls leak when three conditions exist simultaneously: rainwater is on the wall; openings exist through which the rainwater can pass; forces are present to drive or draw the water inward. If any one of these conditions is eliminated, the wall won't leak.
